• A Retailer's Inventory Model for Deteriorating Items under Power Pattern Demand with Shortages Partially Backlogged in both Crisp and Fuzzy Environments  
  by Sourav Kumar Patra, Susanta Kumar Paikray, Rudra Mohan Tripathy 
  Abstract: An inventory predicament can be resolved with numerous techniques, starting from the trial-and-error manner of mathematical and simulation methods. Mathematical methods always serve as powerful tools for minimising total inventory costs. In this paper, we have considered a retailer's inventory problem in order to determine an optimal strategy that minimises the total inventory cost under various constraints. Here, the constraints include constant deterioration, power-pattern demand, permissible shortages, partial backlog, different inventory costs, and inherent imprecision of various expenses concerning the current scenario. Subsequently, we develop the mathematical model of the problem together with its solving policy in a crisp as well as fuzzy environments. Moreover, we provide several numerical illustrations to validate our findings. Finally, we present several managerial insights for inventory managers based on the sensitivity analysis of associated parameters.
  Keywords: inventory optimisation; power demand; deterioration; partial backlogging; triangular fuzzy numbers; signed distance method.

• A conceptual human safety system in an industrial shared workspace with a collaborative robot  
  by Marcos Vido, Athos Pacchini 
  Abstract: By working side-by-side with humans in a production environment, collaborative robots (cobots) can be helpful and versatile and can efficiently support activities in modern factories. A review of the extant literature identified an opportunity to build user-friendly human-robot interfaces and confirmed the need to enhance the perceptions of human safety conditions and requirements during interactions with cobots when performing manufacturing tasks. Therefore, this study seeks to deepen the knowledge regarding the use of cobots, based on introducing novel safety system architecture for human-robot collaboration in a shared workspace. The degree of collaboration is investigated, focusing on the safety requirements when human operators perform tasks involving cooperation between humans and cobots in a combined workstation. As a result, this study extends the previous literature by proposing a conceptual safety system architecture that is especially useful for covering safety requirements during the design stage of a collaborative workstation so as to minimise safety risks to humans, resulting in a dynamic safety framework that allows for the use of advanced robotics in an Industry 4.0 environment.

• Process Capability Indices Cp and Cpk under AR (2) Process  
  by Mahesh Deshpande, Vikas Ghute 
  Abstract: Process capability indices are widely used by quality practitioners to quantify the capability of given manufacturing process. The process capability indices Cp and Cpk are based on the assumptions of independence and normality of the process characteristic. Many authors have reported that if we ignore the autocorrelation present in the process characteristics lead to wrong decisions. In this paper, the effect of the autocorrelation on the capability indices Cp and Cpk is discussed. The second order autoregressive process AR (2) is considered to model the data from an autocorrelated process. To reduce the effect of autocorrelation on the indices and the skip and mixed sampling techniques are implemented to form rational subgroups in the design of these indices. Results based on simulation study confirm that both the techniques improve estimate of capability indices Cp and Cpk significantly.
  Keywords: process capability index; subgroup; autoregressive process; s-skip and mixed sampling.

• Customer Satisfaction Optimization in a Dynamic Closed-Loop Supply Chain under uncertainty  
  by Hanieh Shambayati, Mohsen Shafiei Nikabadi, Mohammad Rahmanimanesh 
  Abstract: Optimising the management of the closed-loop supply chain (CLSC) has attracted considerable attention over the past few years. But most researches in this area have only considered the cost and profit functions. In this research, the optimisation of Multi-product CLSC considering customer satisfaction with dimensions such as quality, service level, lead time, and environmental pollution along with the profit function in different periods is considered. The uncertainty of demand in the form of grey numbers is considered. To optimise this NP-hard problem, a multi-objective meta-heuristic pareto-based enhanced firefly algorithm was used. The purpose of the proposed model is to determine the optimal production quantities of each product and finding the location of the warehouse at each stage and period in the CLSC. Finally, for the validity and analysis of the model, a numerical example has been considered.

• Machine learning based conflict-free trajectory generation  
  by Yungxian HAN 
  Abstract: With the rapid development of the aviation industry, air traffic flow is showing a rapid growth trend, and the mutual influence and interference between aircraft in the airspace are also increasing. In order to ensure the safe and orderly operation of air traffic flow, it is urgent to propose efficient conflict-free trajectory generation methods. The development of artificial intelligence technology provides a new way for the design of conflict-free trajectory generation algorithms. As a consequence, machine learning can be applied to conflict-free trajectory generation. Intelligent agents learn autonomously in their interactions with the environment, thus possessing the ability to make autonomous decisions. Simulation experiments in different scenarios have shown that the algorithm proposed is effective.

• A Game-Theoretic Approach for Analyzing a Competition Between Electric and Hydrogen-Based Vehicles in a Supply Chain to Reduce Carbon Emission Under Government Strategies  
  by Mahnaz Naghsh Nilchi, Morteza Rasti-Barzoki 
  Abstract: In recent decades, climate change and air pollution have become major global challenges due to population growth and increased fossil fuel use. Electric and hydrogen vehicles have emerged as sustainable alternatives, reducing greenhouse gas emissions and improving air quality. Both offer co-benefits in reducing air pollutants from common emission sources. However, the study shows that despite higher demand for electric cars, hydrogen car manufacturers still yield greater profits. The preference for consumers and governments is more towards electric cars due to higher demand and better environmental impact. Nevertheless, the hydrogen car market remains profitable for manufacturers. Governments may play a role through tax and subsidy policies to incentivise consumers towards more sustainable choices, contributing to environmental protection and public health preservation.

• Performance and Reliability Analysis of Pulping system in a Paper Plant  
  by Seema Sharma, Mamta . 
  Abstract: This paper presents the performance and reliability analysis of the pulping system in a repairable paper plant utilising the fuzzy y - method based on trapezoidal fuzzy numbers. The configuration of the pulping system has been modelled by the Petri net model. To deal with imprecision and vagueness in failure/repair data, trapezoidal fuzzy numbers are used to fuzzify the failure and repair data of each component of the pulping system. The fuzzy - method has been utilised to evaluate reliability factors of the pulping system including availability, reliability, failure rate, repair time, mean time between failures and expected number of failures at different spreads. The analysis is beneficial for plant managers to enhance the performance of the pulping system by developing and implementing appropriate maintenance strategies and policies.

• Data-driven distributed control of input-coupled interconnected systems based on Nash optimality  
  by Dawei Zhang, Shouli Gao, Rui Xia, Dongya Zhao 
  Abstract: This paper introduces a data-driven distributed controller for interconnected systems with input coupling of unknown models. The estimation of input coupling terms does not depend on historical data. The complex interconnected systems with input couplings are decomposed into individual subsystems. The proposed strategy not only alleviates computational load, but also optimises the interaction between subsystems, effectively addressing the output oscillations of the system during abrupt reactions of input couplings. The convergence of the control algorithm and the stability of the closed-loop system response are examined, and the efficacy of the proposed control method is validated by comparative simulations.

• Multi-period and multi-workday workforce scheduling for manufacturing workstations with multiple worker  
  by Tarit Rattanamanee, Suebsak Nanthavanij 
  Abstract: This paper discusses the complex workforce scheduling problem where a workday is divided into multiple periods and the planning horizon is extended to cover several workdays, or MPMW-WSP. Additionally, there can be multiple workers at individual manufacturing workstations. The MPMW-WSP focuses on the safe exposure of workers to a given ergonomic hazard that is dominantly present in the workplace. Dominant ergonomic hazard can be either a single-limit hazard or variable-limit hazard. A hybrid solution procedure is employed to solve the problem. It consists of a heuristic method to estimate an initial workforce size and an integer linear programming (ILP) model to determine a minimum number of workers to be rotated among different tasks so that their daily hazard exposures are within the permissible or recommended limit. Numerical examples and computation experiment are also presented.
  Keywords: workforce scheduling; job rotation; ergonomic hazard; hazard exposure; optimisation.

• Improving satisfaction of waiting customers by personalized service  
  by Junxiang Li, Xiaran Gao, Chenglong Li, Xiaojia Ma 
  Abstract: Queuing problem is considerably important in a service field. The customers’ waiting satisfaction in the process of queuing has a large impact on the whole service. A queuing model providing personalised service is constructed to improve the satisfaction of waiting customers. The enterprise's extra service cost, waiting satisfaction and the customer's actual utility after service are analysed to increase the proportion of satisfied customers by using arena, a simulation software. By comparing with other queuing systems, the results show that the proportion of customers seeking personalised service, their willingness to get extra service and their queuing position of providing extra service have an important impact on the proportion of satisfied customers. The research can offer an important reference for contact centres and other service fields.

  by Ashwani Kharola 
  Abstract: This study investigates nonlinear autoregressive neural network (NARNET) and nonlinear autoregressive neural network with exogenous input (NARXNET)-based artificial neural network (ANN) models for multistep prediction of specific enthalpy of steam. Real-time experimental data on specific enthalpy of steam has been collected and used for training of proposed models. The machine learning models have been trained using different training algorithms namely Levenberg-Marquardt (LM), Bayesian-regularisation (BR), scaled-conjugate gradient (SCG), one step secant (OSS) and resilient back-propagation (RB). The prediction performance of these algorithms have been analysed in terms of root mean square error (RMSE), mean absolute error (MAE), mean absolute percentage error (MAPE) and bivariate correlation coefficient (COR) for a maximum step size of 30 multistep predictions. The results highlight superior performance of NARXNET model designed using BR-algorithm compared to prediction models designed using other training algorithms.

• A bearing fault diagnosis and monitoring software system based on lightweight neural networks to resist coloured noise  
  by Wujiu Pan, Yinghao Sun, Shuming Cao, Kuishan Kong, Junyi Wang, Peng Nie 
  Abstract: In actual industrial sites, the application of bearings is becoming increasingly widespread. In order to better monitor the faults of bearings, this article combines the concept of deep learning and designs a bearing fault diagnosis and monitoring software system based on lightweight neural networks to resist coloured noise. This system is developed based on MATLAB App Designer. When testing the system, five different bearing datasets, namely MFPT, Paderborn, IMS, Ottawa, and CWRU, are applied. Considering that the data in actual scenarios contains complex noise, coloured noise signals are added. Compared to traditional fault diagnosis software that requires pre writing data into the program, this software can perform real-time processing on any single column vibration data file. By using lightweight neural network methods to preprocess the data collected by sensors, the SqueezeNet network has a faster speed to extract significant features of vibration. This software system can achieve time-frequency domain image output of signals, with multiple noise reduction methods. It can also calculate the frequency of faults based on bearing model data. Through envelope spectrum images, the location of faults can be monitored and email reminders can be sent to engineers.

• Reliability assessment of a NSP system under constant triangular fuzzy failure rates  
  by S. Malik, Suresh Chandra Malik, Naveen Nandal, A.D. Yadav 
  Abstract: Here, the reliability of a non-series-parallel system (NSP) has been examined considering fuzzy failure rates. There are seven non-identical components in the system, which are arranged into three structures. The two structures operate in parallel and each having three components connected in series; while the third structure has a single component connected with the extreme components of the parallel structures. The expression for reliability of the system is assessed using the path tracing method. The failure rate of the components is assumed as constant triangular fuzzy number and thus they follow the exponential distribution. The a-cut method is used to defuzzify these fuzzy numbers for determining reliability measures. The intervals for fuzzy reliability and MTSF of the system have been computed for both non-identical and identical components. An illustration of RLC system has been described to highlight the application part of the research work.

• Optimizing Multiple Sclerosis Detection: Harnessing Cutting-Edge MRI Image Analysis for Advanced Industrial Diagnosis  
  by Mohammed Obeidat, Hussam Alshraideh, Abedallah A.L. Kader, Rabah Al Abdi, Morad Etier, Nohammad Hamasha 
  Abstract: Human brain disorders are those abnormal changes that occur around or inside brain parts. These disorders include infections, tumours, trauma, degeneration, structural defects, stroke, and autoimmune disorders. The devastating consequences of brain disorders on the lives of humans could be reduced by early diagnosis. The diagnosis of brain disorders consumes higher time and effort by physicians compared to computerised diagnosis techniques. Several computerised diagnosis algorithms have been developed to improve and optimise the diagnostic capabilities of physicians. Magnetic resonance imaging (MRI) is an effective tool used for brain disorders diagnosis. MRI detection of multiple sclerosis (MS) is extremely complicated due to several reasons, including the anatomical variability between patients, lesion location, and the variability in lesion’s shape. This paper reviews several computerised algorithms used in diagnosing brain disorders, to present the most efficient techniques that reduce the physicians’ diagnosis time and effort of MRI images, hence, starting MS treatment at earlier stages.

• The impact of difficulty and expensive financing on energy industry conservation and emission reduction  
  by Zihan Xia 
  Abstract: This article separates the issues of financing difficulties and high financing costs, and studies the impact of financing difficulties and high financing costs on the energy-saving and emission reduction behaviour of enterprises. We find that when the problem of difficult financing for enterprises exists, the approved loan amount positively affects the level of energy conservation and emission reduction through production volume; The level of energy conservation and emission reduction is not related to the loan interest rate. The fixed cost investment in energy conservation and emission reduction is a major factor for enterprises to take energy conservation and emission reduction measures. Even with financing difficulties, because of the existence of carbon taxes and subsidies, companies tend to adopt energy-saving and emission reduction measures. The heterogeneity of enterprise scale only exists when financing difficulties exist. Once financing difficulties are resolved, there is no heterogeneity in the impact of enterprise scale on energy conservation and emission reduction levels. This means that the energy conservation and emission reduction levels of enterprises of different scales are ultimately the same.

• Optimizing Parcel Count in E-commerce Fulfillment with Mixed-Split Order Picking  
  by Wen Zhu, Jingran Zhang, Sanchoy Das 
  Abstract: E-commerce fulfilment warehouses (e-warehouses) store thousands of items and fulfil thousands of online customer orders every day. E-warehouses are operationally different from traditional warehouses. To accelerate fulfilment speed, an e-warehouse splits multi-line orders across multiple picklists. A key research question is how to manage the flow of picked items so that the number of shipped parcels is minimised. This research introduces the e-warehouse order consolidation (WOC) problem. Tote consolidation is a key link between order picking and parcel packing. We identify key modelling elements and formulate the associated constraints and objectives. The WOC mixed integer program is tested on a series of problems, and we illustrate the operational and business value of controlling the tote consolidation process. Order similarity between totes is used to develop two fast heuristics. Two controllable design parameters are investigated, the number of packing stations and the number of totes assigned simultaneously, on parcel packing efficiency.
  Keywords: fulfilment speed; shipping costs; parcel packing.

• Jordan's Future Renewable Energy Stability and Break-even Analysis Under Various Catalysts Using System Dynamics  
  by Samer Abaddi 
  Abstract: The social acceptability of photovoltaic (PV) systems contributes not only to the amount of power generated but also to the CO2 emissions reduction in Jordan. The effect of three catalysts; subsidy proportion, Word of Mouth (WOM) and advertising effectiveness is addressed in this piece of work, in addition to a forecast of the power generated and the CO2 emissions reduction by 2080. System dynamics (SD) is the fundamental approach of this study. Qualitative interviews and energy reports assisted the data collection process and simulation was conducted between 2020 and 2080. Six scenarios are hypothesised to facilitate the comparison between the catalyst's effects with the help of break-even point analysis. Jordan is expected to generate 1.845 Terra Wh (TWh) and 995.9 TWh of energy by 2040 and 2080, respectively. The CO2 emissions reduction is expected to cross 630 million tons by 2080. Advertising effectiveness was found to be the top catalyst that stimulates the power generated in Jordan followed by WOM. The quantitative models foster the policy makers towards investing in social acceptability dimensions toward achieving earlier equivalency of demand and supply. This is the first study in Jordan that develops break-even calculations at various levels of catalysts using SD.

• An Enhanced Fractional-order Fuzzy Controller Design for an Integrated Power System using a Counteractive Control Action  
  by Devbrat Gupta, Jitendra Kumar, Vishal Goyal 
  Abstract: This research article reports an efficient control of the Integrated Power System (IPS) using a fractional-order fuzzy proportional and derivative (FOFPD) controller combined with a fractional-order integral and derivative (FOID) controller in order to overcome the sudden variation in microgrid frequency problem. The novelty of the anticipated control strategy lies in the use of FOID control action, which generates the counteractive action to improve the control performance. The controller's gains are optimised by an optimisation algorithm called spider-monkey optimisation (SMO). The objective function is considered as the sum of the integral of the squared deviation of the microgrid frequency (ISFD). The proposed controller's response is then compared with the integer-order counterparts to investigate the effectiveness of the suggested controller. The detailed simulation results demonstrate the robust behaviour of the proposed control scheme and establish its superiority over other investigated control structures.

• PROMETHEE vs. OptQuest for simulation-based multi-objective optimisation approach in flexible manufacturing system  
  by Abdessalem Jerbi, Mohamed Ali ELLEUCH 
  Abstract: Flexible manufacturing system design is a complex problem because of its stochastic nature, especially when there are multiple optimisation objectives to consider. For this reason, various studies have relied on discrete event simulation tools to create and evaluate the flexible manufacturing system's performance using multi-objective optimisation methods. However, the literature lacks comparative studies of these different methods in the flexible manufacturing systems optimisation context. This paper aims to compare the two optimisation methods, PROMETHEE and OptQuest, based on multi-objective efficiency. PROMETHEE is based on ranking simulation results, while OptQuest is an iterative method using a meta-heuristic. This comparison showed that OptQuest is the best-performing method.

  by Vikram Singh, Somesh Kumar Sharma 
  Abstract: High-tech product manufacturers operate in extremely sensitive environments and face challenges in meeting the quality standards of high-tech products. To address these challenges, this study aims analysing the impact of multi-agent technology (MAT) on the quality standards of high-tech manufacturing (HTM). The extensive literature was used to explore eight factors of HTM and forty-five variables of MAT. A hybrid multi-criteria decision-making technique was used to analyse the factors and variables. The HTM Process is a highly prioritised and impactful factor. Process monitoring, automatic customised test plans, adaptive agents, demand forecasting agents, and virtual manufacturing are the top five globally ranked variables. The findings of this article provide ranking order and determine the relationship between factors and variables for the integration of MAT in HTM. This bridging can assist designers in improving the design quality, manufacturers in increasing process quality standards of products, and market experts in selecting the potential market.

• A Systematic Literature Network Analysis Approach to Assess the Topology of Modern-era Supply Chain Risk Management Research  
  by Leslie Dass, Sreerengan V.R. Nair, Georgy Kurien, Dr S. Kumar Chandar 
  Abstract: Over the past decade, there has been a significant increase in research on supply chain risk management (SCRM). This review uses a systematic literature network analysis to provide an overview of the SCRM research landscape, with emphasis on optimisation approaches, mathematical modelling tools, and the identification of seminal studies and relevant keywords used in SCRM research. However, there are few quantitative models that represent the relationship between supply chain surplus, sustainability, and resilience in SCRM literature. The study has limitations since it only sources from a single database, and more clarity is needed on the effectiveness of optimisation in SCRM, which can be further evaluated through case studies and empirical studies.

• Blockchain technology adoption in healthcare: a systematic review and conceptual framework  
  by Ashraf Abdou, Basma Ezzat, Sharif Mazen, Nagy Ramadan 
  Abstract: Recently, blockchain technology has attracted a lot of interest from different researchers and academics due to its unique properties like immutability, interoperability, and confidentiality. However, to date, their adoption in the healthcare sector is still very limited. Few studies applied a systematic literature review (SLR) for blockchain adoption in healthcare. In this research study, the first contribution is to identify the factors that influence the adoption of blockchain by applying the SLR approach, understand how these factors are interrelated, and discuss the main challenges of blockchain adoption. The findings demonstrated that, the unified theory of acceptance and use of technology (UTAUT), the technology acceptance model (TAM) and its extension were the most popular models used for blockchain adoption. Then, we identified the key research gaps and proposed a conceptual framework to address the identified gaps to be a reference and guide for organisations adopting blockchain in healthcare.

• Portable Coconut Tree Climbing Device and its Analysis  
  by Ravi Kumar Mandava  
  Abstract: Coconut tree is one of the useful plant among all other plants. Due to the lack of coconut tree climbers worldwide, many coconut palm growers are not interested in cultivating coconut farming. Based on the above problem, numerous researchers have developed various climbing mechanisms. To overcome this problem a novel coconut tree climbing device (CTCD) was introduced which can climb the coconut tree up to the canopy. To check the deformation behaviour and generated stresses of various parts of the device in the present research work, the authors conducted dynamic analysis, such as modal, harmonic, and transient analysis in ANSYS 2021. Moreover, the dynamic properties of each component will also be tested under vibrational excitation. Therefore, one of the vibrational properties, that is, the natural frequency, is used to analyse the effect of transient loads and avoid the noise and vibration hazards in the components of the coconut tree climbing mechanism.

• SDAPI: A Systematic Approach to Integrating Industry 4.0 and Lean Manufacturing for SME Improvement  
  by Hafsa El-Kaime, Saad Lissane Elha 
  Abstract: Many businesses, particularly small and medium-sized enterprises (SMEs), seek to improve productivity and reduce resource usage. Lean manufacturing (LM) is a popular method for optimising processes by eliminating non-value-added activities and improving efficiency and flexibility. However, in today's rapidly changing technological and market environment, companies must also adopt innovative production management approaches to stay competitive. The Fourth Industrial Revolution and related technologies offer the opportunity to take current manufacturing systems to the next level. While previous research has explored the concept of Lean 4.0, which combines Industry 4.0 and LM, there has been less focus on the relationship between methodological approaches and technological concepts. This research aims to fill this gap by presenting a methodological-technological framework for implementing Industry 4.0 technologies in SMEs in order to achieve the objectives of LM. The proposed methodology, called SDAPI, is developed through a literature reviews, it consists of five steps: specify, detect, analyse, propose, and implement.

This study aims to improve the quality of manufacturing processes from material acquisition to the end of production using multi-agent technology (MAT). The literature review identified five factors and their 31 governing variables, and their impact is analysed through AHP, DEMATEL, and TOPSIS. AHP was used to study and establish priority orders. DEMATEL was used to develop inter-relationship and TOPSIS to validate the global ranking evolved through AHP. Manufacturing Process along with Quality Aspects are evolved most significant factors for controlling quality. Their significance is increased since they were discovered to be the most influential in affecting other factors. The detailed research and discussions in this article may allow industrial organisations to raise quality standards, hence increasing customer support, lowering costs, and improving efficiency.

• A comprehensive approach to UA Facility Layout Design Using Genetic Algorithm  
  by Kamal Deep 
  Abstract: Facility layout panning is a quantum leap for the production industry to realise the low entropy, widely applied to the unequal area facility layout problems (UA-FLPs). This paper aims at the optimisation of UA-facility layout in the flexible bays structure (FBS) to maximise the adjacency requirements of facility types for the production layout. The FBS is a most commonly used structure flexible to allocate the facilities in the bays of unequal areas permitting empty space in the total area of the layout. The proposed mixed integer programming model has been formulated to ensure; minimum side length, confined aspect ratio of facility types, and optimal space utilisation in the total area of facility layout. The genetic algorithm based heuristic has been used to search the discrete solution space in a feasible time span. The optimal results obtained are mapped with the best known numerical instances reported in the literature to approve the efficacy of proposed solution approach.

• Multi-Objective Optimization in Turning AISI 304 Stainless Steel: An Integration of The Taguchi Method, Response Surface Methodology, and NSGA-II  
  by Cong Chi Tran, Thi Tham Nguyen, Van Tuu Nguyen 
  Abstract: This study examined the impact of machining parameters [depth of cut (d), feed rate (f), and spindle speed (s)] on surface roughness and material removal rate in the turning process of AISI 304 stainless steel. Three optimisation methods were used: the Taguchi method, the response surface methodology (RSM), and the non-dominated sorting genetic algorithm II (NSGA-II). The Taguchi method identified the most influential parameter for surface roughness (f > d > s) and for material removal rate (d > f > s). RSM regression models achieved high R2 values of 0.9896 for roughness and 0.9997 for material removal rate. NSGA-II multi-objective optimisation produced 35 Pareto solutions within ranges of cutting parameters, resulting in surface roughness values from 0.239 to 3.301 ?m and material removal rates from 151.53 to 594.99 mm3/s. Confirmation experiments validated the optimal values, with deviations within 10%, confirming the accuracy of the research method for solving the optimisation problem.

• Reliability Analysis of Bleaching System in a Paper Industry  
  by Seema Sharma, Mamta . 
  Abstract: This paper presents a fuzzy technique to examine the reliability of bleaching system in a paper industry using uncertain data. The uncertainties in failure/repair data of every subsystem/component of the bleaching system are quantified using two types of fuzzy numbers, trapezoidal and triangular fuzzy numbers. The basic arrangement of components/subsystems of bleaching system is represented using Petri net model. The fuzzy values of various reliability metrics of bleaching system for different uncertainty levels have been evaluated employing fuzzy - technique. Subsequently, to analyse the failure behaviour of bleaching system and to plan for suitable maintenance policies, these fuzzy values have been defuzzified using centre of area method. The analysis is useful for plant managers to improve the performance of bleaching system by establishing and implementing appropriate maintenance strategies and policies.

• A Hybrid Optimisation Strategy for Large-Scale Vehicle Routing Problems with Time Windows using Solution Initialisation  
  by Yongzhong Wu, Minqi Xu, Mianmian Huang 
  Abstract: This paper investigates a novel hybrid optimisation strategy that integrates a machine learning algorithm with a meta-heuristics to tackle large-scale vehicle routing problems with time windows (VRPTW). Specifically, the K-means clustering algorithm is employed to generate initial routing solutions, subsequently optimised by an artificial bee colony (ABC) algorithm. The new approach is tested on large-scale real-life cases. The computational results show that the new algorithm outperforms a well-established ABC algorithm in terms of both objective value and computation time. In addition, the experiments highlight the importance of considering both the distance between customers and customer time windows in the clustering process to ensure good computational results.

  by Dong Zhang, Yazhen Lan, Shan Hu 
  Abstract: This study addresses the absence of design standards for cognitive training apps catering to seniors with mild cognitive impairment (MCI). Integrating qualitative and quantitative methods, it employs grounded theory (GT) for synthesising user interview data and iteratively refines design criteria through theoretical coding. The fuzzy analytic hierarchy process (FAHP) and criteria importance through intercriteria correlation (CRITIC) objectively establish weights for design evaluation criteria and finalise the weighting values using the combined ideal point assignment method. The VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) is used to evaluate and select design solutions. This comprehensive approach minimises subjectivity and bias in criteria determination and weighting, enhancing the Objectivity and accuracy of cognitive training application evaluations. Usability questionnaires and user testing validate that the integrated approach improves design decisions' objectivity and scientificity, making the application more responsive to user needs.

• Variant-Rich New Energy Vehicle Powertrain Functional Safety Engineering  
  by Roland Mader 
  Abstract: New energy vehicles (NEVs) are a success story that has led to the continuous introduction of manifold vehicle models and variants. Due to the fact that NEV powertrains are controlled by E/E (electrical and/or electronic) systems, faults and failures of these systems can lead to hazards. In order to prevent such hazards, functional safety engineering aims at avoiding or mitigating safety-critical E/E system faults and failures on the system, hardware and software level. Accordingly, numerous functional safety activities need to be executed and many workproducts are required. Variability of NEVs, high requirements as to achieve functional safety, short development cycles and resource constraints impose challenges for automotive companies. Motivated by an industrial case study we identify variation points of NEV powertrains and analyse their dependencies on the functional safety lifecycle. Based on that, we identify organisational and technical measures which support variant-rich new energy vehicle powertrain functional safety engineering.

• Optimal operation of microgrid systems considering user energy storage behavior  
  by Junxiang Li, Chenmin Gong, Deqiang Qu, Xi Wang 
  Abstract: This paper establishes a microgrid system optimisation model based on carbon capture and shared energy storage to promote new energy consumption and better reduce carbon emissions. Considering the user's psychology and demand response, the energy storage behaviour of users is analysed to maximise the benefit of energy storage and achieve a win-win situation for both load aggregators and shared energy storage providers. The pricing and energy supply strategies of microgrid operators are optimised based on carbon capture technology. A case study is conducted on a microgrid system located in a business park in southern China. Through numerical simulation and comparative analysis of multiple scenes, it is verified that carbon capture devices and shared energy storage can significantly reduce the microgrid's carbon emissions and the uncertainty of the system operation and improve users'; demand response capability, which is beneficial to the long-term development of the microgrid system.

• Effects of building parameters on mechanical and surface properties of 3D printed bioplastic (PLA) using TOPSIS: An experimental study  
  by Senthil S. M, Bhuvanesh Kumar M, Rajeshkumar L, Sampada Viraj Dravid 
  Abstract: Additive manufacturing is becoming an emerging technology in manufacturing three dimensional (3D) components in a layer-by-layer printing fashion. The technology enables wide variety of materials to be printed for different applications starting from automotive, aerospace, marine and to the biomedical fields. 3D printing processes are majorly used to print polymeric materials compared to metallic materials. Polylactic acid (PLA) is the most commonly used material by the fused deposition modelling technique, which accounts for multiple applications. The present study investigates the effect of printing parameters such as infill density, wall thickness, printing speed and ironing to identify optimum process parameter combination for better mechanical performance. Based on the design of experiments, 40 samples were printed and measured for mechanical characteristics. Upon the analysis using TOPSIS, at the parameter combination of infill density (99%), wall thickness (3 mm), and printing speed (150 mm/hr), the printed specimens showed higher tensile strength of 10.20 MPa and comparatively good surface finish. Hence the parameter optimisation showed a positive influence on enhancing the mechanical properties of printed components.

• A Study on the Application of Emotional Factors in Medical Products for Paediatric Asthma  
  by Jun Wang, Yazhen Lan, Dong Zhang, Mengqing Liu 
  Abstract: Emotional factors play a pivotal role in enhancing the user experience of medical products for paediatric asthma, mitigating children's negative emotions, and improving treatment adherence. However, a comprehensive framework and assessment criteria for integrating emotional factors into the design of such medical products are lacking. To standardise these criteria, this study integrates emotional design theory, grounded theory, and the fuzzy analytic hierarchy process (FAHP). Firstly, based on the three-level theory of emotional design, an interview outline was constructed to conduct semi-structured interviews with the target users, and the interview content was coded and analysed using the grounded theory to refine the emotional factor design indicators. Subsequently, FAHP assigned weights to these indicators, constructing a comprehensive emotional factor application model. PSSUQ validated product usability, revealing that the proposed model effectively meets users’ emotional needs, thereby standardising emotional factors application criteria and offering theoretical references for designing medical products for paediatric asthma.

• Reliable Location Models with Transportation Mode Selection (RLM-TMS)  
  by Leena Hamdan, Abdulrahman Alenezi 
  Abstract: In this study, we examined a three-echelon supply chain network consisting of candidate facilities, hubs, and customers. Products are delivered from facilities to customers directly or via hubs, utilising different transportation modes. Full truckload shipments are employed for delivering products from facilities to customers or hubs, while less than truckload shipments are utilised for products from hubs to customers. Considering the susceptibility of facilities to failure, customers are allocated to either a primary facility exclusively or both primary and secondary facilities, with the secondary facility serving customers only during the failure period. The problem is mathematically formulated as a linear integer programming model and subsequently solved using the Lagrange relaxation procedure. The solution was obtained with an average computational time of 96.6 seconds, demonstrating a gap between upper and lower bounds averaging 0.158%.

• Quantifying the Influence of Future Disruptive Scenarios to Priorities of Energy Supply Chains Systems of Liquified Petroleum Gas  
  by Ayedh Almutairi, Fatmah Alfaqeeh, Zachary Collier, James H. Lambert 
  Abstract: The availability of liquified petroleum gas (LPG) is especially critical for commercial and residential users. A risk assessment framework has been established to track risk scenarios and to address the level of disruptions on the priority orders of initiatives under the influences of scenarios. It demonstrated in an LPG facility in the State of Kuwait with 17 emergent conditions, 3 scenarios, 15 initiatives, and 4 evaluation criteria. The shutting down of one centre and the shutting down of two centres were the most disruptive scenarios. The highest ranked initiatives are: Increasing the number of workers for inspection, having random weekly inspections, and having monthly maintenance, respectively. However, these initiatives are the least robust to disruptive scenarios' impact. The initiative, raising customers' awareness of how to safely use LPG cylinders, has the least priority ranking order but is the most robust initiative to the influence of scenarios.

  Abstract: CEED solution is the procedure of dividing up the required demand of power among the possible producing units while taking into account low fuel costs, decreased emissions, and minimal transmission loss. The multiple objective functions are formulated to single CEED constraint to solve using an efficient algorithm. By combining the peculiar preying characteristics of Harris Hawk and the intellectual food storage characteristics of crow, a novel MIHHO Algorithm is designed to handle the CEED constraint. The efficiency of the optimisation strategy is evaluated with six test cases. The minimised results of transmission loss, economic cost and emission cost for the DG system by MIHHO technique is evaluated over the traditional strategies, such as GA, GWO, WOA, CSA and HHOA. From the outcomes, it is evident that the proposed MIHHO algorithm provides better solution as compared over the existing methods.

• A Multimedia based Patterns Retrieval from Database Patterns and Storing  
  by Vilas Baburao Khedekar, Dharmendra Singh Rajput 
  Abstract: In this work, a novel multimedia Pattern retrieval system is introduced that encapsulates three major phases: 1) feature extraction; 2) pattern generation; 3) pattern matching. The SURF features have been extracted from the audio input and text input. In addition, the video input is converted into RGB to greyscale format, and then the SURF features are extracted from it. The pattern generation phase includes three stages: 1) scaling of features; 2) rules generation with Association rule mining algorithm; 3) optimised rule generation. Initially, the extracted feature is scaled within limits 1 to 20, and the rules are generated for the video, audio, and text signals separately using the Association rule mining algorithm. Moreover, the optimised rules are generated from the extracted rules using the improved GOA model. Then, using the map-reduce framework, the correlation between them is validated.

• LOT Streaming Optimisation of Scheduling Problems in Open-Shop Manufacturing Environments  
  by Ammar Al-Bazi, Mahmood Ahmad, Mohammad Shbool, Anees Abu-Monshar, Rami Hikmat Al-Hadeethi, AbdulStattar Al-Alusi 
  Abstract: Scheduling manufacturing operations is vital for companies to thrive under high competition in various manufacturing industries. The production scheduling process allocates resources such as time for each specific operation, detects possible conflicts of allocated resources, controls job release timings on the shop floor, ensures delivery due dates, and thus increases the productivity and efficiency of the workforce. In this paper, a method usually exploited to reduce the production duration, dubbed lot streaming, is adapted and applied to solve scheduling problems in open shop environments. A new integer linear programming (ILP) model is developed to outline the integration of lot streaming scheduling and constraints of partial functionality machines in an open shop environment to minimise the makespan. In such an environment, there are no restrictions on the order in which the machines perform the jobs operations. The developed model is applied and tested on five different hypothetical problems. The experimental results are presented, and the efficiency of the proposed ILP is discussed. It is concluded that considerable reductions in the makespan can be achieved with the inclusion of lot streaming in an open shop production environment.

• Resource Allocation Strategy in Fog Computing  
  by Sharmila Patil (Karpe), Brahmananda S. H 
  Abstract: The idea of fog computing enables the delivery of computational services and resources closer to the endpoints and users, at the network's edge. Due to the large number of devices, determining the best resource allocation in this situation is challenging. Accordingly, a unique resource allocation strategy for fog computing is suggested in this work. The resource allocation of fog computing is made possible by the modeling of a non-linear functionality under the objective function comprising metrics like Service response rate, Execution time, make span, resource consumption, and Reboot rate. The proposed approach also takes consideration for the allocation of resources in urgent scenarios that allow for quick resource distribution. Considering this as the optimization problem, a new optimization model termed as Hybrid Coati Insisted Beluga Whale Optimization (HCIBWO) is introduced in this work. The performance of proposed work is evaluated over the conventional models in terms of different measures.

• Optimisation of Surface Roughness of FDM Fabricated Parts: Application of Definitive Screening Design and Genetic Algorithm Techniques  
  by V. Chowdary Boppana, Fahraz Ali 
  Abstract: This study presents an experimental investigation on the impact of variations in various fused deposition modelling (FDM) process parameters such as layer thickness, build orientation, raster angle, part raster width, raster to raster air gap, number of contours, contour width and part shrinkage factors on the top surface roughness of FDM printed poly-carbonate parts. To meet the study objective, definitive screening design (DSD) and ANOVA techniques were used to develop a predictive model for establishment of a functional relationship between the selected process parameters and part surface roughness. Thereafter, the predictive model was validated and optimised using genetic algorithm (GA) technique. The comparison of optimal and default process parameter settings showed an improvement in surface roughness of 60.9%. The proposed combined DSD-GA approach can assist practitioners in fabrication of various industrial products to uplift the additive manufacturing (AM) sector.

  by Mehari Bezuneh, Bereket Haile, Assefa Tsegaw, Teshome Bogale, Matthias Brossog, Jörg Franke 
  Abstract: Globalisation, market uncertainty, changing customer interests, and shorter product life cycles pose computational challenges to the manufacturing industry. Mass customisation (MC) has emerged as a solution to tackle these challenges by offering customised products while maintaining product cost, quality, volume, variety, and delivery time, which are called competitive factors in the manufacturing industry. However, the effectiveness of the MC strategy depends on how effectively the industry applies different manufacturing systems. Therefore, the main objectives of this research were to identify and determine how the manufacturing system enhances MC capabilities and contributes to the competitiveness of the manufacturing industry. The process involved formulating hypotheses after reviewing existing literature and gathering expert opinions and analyses using the algorithms of the fuzzy Delphi method. Ultimately, this study identified the basic manufacturing systems that can increase MC capabilities, which contributes to improving the competitiveness of the manufacturing industry.

  Abstract: The development of IIoT is the scarcity of spectrum resources. It consumes a significant amount of energy while increases the system's spectrum effectiveness. This paper shows the resource distribution in Non-Orthogonal Multiple Access models for IIoT applications from the view of power efficiency. In this paper, the hybrid optimization is used for reducing the energy consumption of power resources and channel resources. An Integrated Squid Game with Coati Optimization Algorithm (ISG-COA) is developed by integrating Squid Game Optimizer (SGO) and Coati Optimization Algorithm (COA) for resource allocation in IIoT scenarios. The limitation of user service quality criteria is also added to the existing optimization problem in order to prevent the situation where the data transmission quality is substantially impaired as a result of the system's energy-saving measures. The algorithm's average system energy efficiency is higher according to the strategy performance simulation experiment when compared to traditional resource allocation algorithms.

  by Abdulnasser El-Gaddar, Ahmed Azab, Mohammed Fazle Baki 
  Abstract: With increased global competition and higher demand for sustainability in emerging markets, manufacturers are actively exploring new avenues to reduce production costs without compromising product quality. To address this challenge, a novel mixed integer nonlinear model is formulated by incorporating internal quality costs, environmental impact considerations, and the impact of buffer size, to solve the micro-Computer Aided Process Planning problem. Scope covered is limited to milling operations for a part mix involving different materials being machined. Surface roughness is used to evaluate the desired quality level of finish. The internal quality failure cost model, including scrap and rework, is developed based on Taguchi's quadratic loss function. Mathematical programming is employed to validate the results of Genetic Algorithms (GAs). Because of the nonlinear nature of the model, GAs has been used. Considering strict quality cost measures, the model minimizes internal quality-related costs while minimizing the environmental impact.

• Optimizing Vehicle Safety: Fuzzy Logic-Controlled Automatic Braking Systems  
  by Monika Dhiman, Pratima Manhas 
  Abstract: The alarming rise in road accidents underscores the critical need for effective vehicle brake systems. Vehicles lacking such systems are highly susceptible to accidents, resulting in devastating consequences. Human errors during driving, including delayed reaction times and distractions, contribute significantly to these incidents. An automatic braking system serves as a vital solution to maintain vehicle stability, prevent wheel lock, and avert collisions with obstacles. This study aims to achieve several objectives: design an ultrasonic sensor-based obstacle detection model, create a model for an antilock braking system (ABS). Results from the simulations indicate a substantial 22 percentage improvement in braking torque. The stopping time is improved by 30% by using fuzzy controller in place of PI controller. Consequently, this improvement results in notably shorter stopping times and distances compared to standard PID control, signifying promising advancements in vehicle safety.

  Abstract: This research investigated the order acceptance and scheduling problem in CMS with tardiness cost, the deterioration effects of machines, and the cost of ordering and holding raw materials. Received orders have revenue, processing time, due date, tardiness cost, and decisions about acceptance or rejection are made. We have proposed a Linear programming mathematical modeling with objective profit maximization. Due to the NP-hard nature of the problem, A meta-heuristic algorithm based on a genetic algorithm is introduced to solve large dimensions. The proposed model has been tested in 4 modes: CODH, COFH (removal of the deterioration effect of the machine), CODI (the removal of holding and ordering raw), and CSDH (removal of acceptance and scheduling of all orders). The results show the performance of the proposed algorithm. The authors’ findings help managers to make better decisions, improve supply chain actions, enhance competitive advantage, enhance customer satisfaction and attract more customers.

• Chronological White Shark Optimisation_PyramidNet for Tuberculosis Bacilli Segmentation and Infection Level Identification  
  by Gavendra Singh, Faizur Rashid 
  Abstract: The main objective of this research is to identify the infection level or severity of Tuberculosis (TB) by PyramidNet which is trained by Chronological White Shark Optimization (CWSO). TB is usually caused by Mycobacterium TB bacteria, which generally affects the lungs. This also affects other body parts. Most infections of TB show no symptoms, which is known as latent TB Bacteria causing TB are spread while the infected person sneezes or coughs. Weight loss, night sweats, as well as fever are common symptoms of TB. In this work, finding the severity of TB or its infection level is done by DL enabled optimized algorithm. Here, PyramidNet is a DL model, trained by the proposed CWSO for infection level identification. Also, denoising is carried by the median filter in the pre-processing stage and bacilli segmentation is done by SegNet, trained by the proposed CWSO. Moreover, appropriate features extracted are fed for severity identification of TB by PyramidNet. Furthermore, CWSO is the hybridisation of chronological concept along with WSO.

• An Integrated SEM and Entropy Approach to Analyse the Impact of Multi-Agent Technology on the Quality of High-Tech Products  
  by Hritik Kamta, Vikram Singh, Somesh Kumar Sharma 
  Abstract: The current research contributes to the literature by assessing the role of Multi-Agent Technology (MAT) in the manufacturing of High-tech products. For this, a conceptual model of five factors of high-tech manufacturing and twenty-five variables of MAT (explored from literature) has been constructed. The model is tested through Structure Equation Modelling (SEM) to prioritize and determine the interrelationships among the factors and variables. This evolved High-tech manufacturing process is the highest prioritized factor followed by others while production planning, resource agent, and Intelligent Shop Floor Management based on MAS are the top three variables among others. These outcomes of SEM are cross-examined through Entropy for more accuracy. The research concludes that implication of evolved priority orders in manufacturing organisations may automate systems which can increase quality, and productivity, and reduce maintenance efforts. This research contributes to high-tech manufacturing management and researchers to advance their knowledge and advance their manufacturing capabilities through the strategic application of multi-agent technology.

• Cost-Effectiveness Evaluation in Supply Chain Using Network Data Envelopment Analysis  
  by Faranak Hosseinzadeh Saljooghi, Elham Zaker Harofteh 
  Abstract: Economic difficulties such as high inflation , deep recession and austerity are disastrous for any country . Monitoring and analysis of every economic activity is necessary to prevent such a scenario. The cost-effectiveness (CE) analysis yields an optimal evaluation of economic activity, which emphasises using minimum resources. Numerous techniques are employed to assess cost-effectiveness; however, none apply to internal organisational structures regarding the operational performance metrics of a company. Therefore, this paper presents a new method using data envelopment analysis to measure CE in a two-stage network system so that all outputs of the first stage are used as inputs of the second stage to produce final outputs. We have concluded that the units that display cost-effectiveness are cost-efficiency. Finally, an example elaborates applicability and merits of the proposed method.

• Kansei Engineering Modelling of Intelligent Food Packaging for Beef Products Using Artificial Neural Network Optimisation  
  by Sakir Sakir, Bambang Dwi Argo, Yusuf Hendrawan, Sugiono Sugiono 
  Abstract: Prediction is one of tasks in the application of Artificial Neural Network (ANN). The utilization of ANN has recently become widespread for predicting product designs, but most research only used one algorithm to train a small dataset. Therefore, this research aimed to predict the design of Kansei engineering-based Intelligent Food Packaging (IFP) for beef products. The dataset comprised 418 inputs, derived from combinations of 19 Kansei words and 22 categories of packaging design attributes. An ANN model was developed and trained by comparing 11 learning function algorithms. This research addressed the gap in predicting the design of IFP using various ANN training algorithms. The results showed that ANN trained with the Gradient Descent backpropagation algorithm (traingd) provided the highest accuracy. Traingd showed the best fit with the highest R and R2 values as well as the lowest MSE, MAD, and RMSE of 0.9949, 0.98915, 0.0333, 2.1353E-05, and 0.00043656, respectively.

• Handover Mechanism of SDN using Puzzle Spotted Henna Optimisation  
  by Pallavi Sapkale, Vaishali Jadhav, Baban Uttamrao Rindhe, Pandharinath Appasaheb Ghonge, Sanjay Ramkrshnan Sange, Moresh M. Mukhedkar 
  Abstract: In recent years, the vehicular ad hoc network (VANET) has been utilised to facilitate connections between vehicles and everything (V2X) and vehicle-to-vehicle (V2V). The speed of data transfer is impacted by the frequent handoffs between road side units (RSUs). To address such issues, this work develops the puzzle spotted Henna optimisation algorithm (PSHOA) for effectual handover. The satellite, RSU, and software-defined networking (SDN) controllers are presented in the SDN control layer. During the handover procedure, the control layer selects the appropriate candidate RSU using the PSHOA. The vehicle connects to the web server and transmits the data across the pathways when it receives the handover order. The end-to-end delay, handover quality of RSU selection, and throughput metrics are used to assess the performance of the system, in which the ideal values of 0.701 s, 0.922, and 95.08 Mbps are obtained.

  by Senthilnathan Chidambaranathan, Faizan Ahmad, Vijayakumari Rodda, Roopa Chandrika Rajappan, Venkateswaran R., Sangeetha S 
  Abstract: Recently, a rapidly developing neurodegenerative disorder is Parkinson’s disease (PD) which commonly affects the population of elder persons of individuals over 50 years. There’s been no medication for PD still now. Despite that, in the early stages, detecting PD is challenging. Thus, earlier detection is required to maximise the life of patients. In this research, the major intention is to project FedL_WFSA_ResneXt-DNN for identifying PD detection. Two entities are involved such as nodes and servers, whereas the models that exist in FL are training and global models. By acquiring the input image from the given dataset, PD detection takes place inside the local training model and the input image is pre-processed using a weighted median filter. The essential features are extracted and then, PD detection is performed by ResNeXt-DNN and the hyperparameters tuning is conducted utilising the proposed WFSA.

• Using Constraint Programming to Avoid Overlapping Physical Components in System of Systems  
  by Hamza Cherif Bouchaour, Haffaf Hafid 
  Abstract: The term system of systems (SoS) refers to a collection of independent systems that combine their functionalities to create a higher-level system capable of achieving broader objectives. SoS relies on the integration of multiple independent complex systems into a unified entity. This complexity makes them difficult to design, manage, and maintain. The reconfiguration phase represents a pivotal aspect of SoS, given the interdependence among its constituent systems, which renders them susceptible to disruptive events. When a single system experiences disruption, it can trigger a domino effect that impacts other systems. The distinctive feature of this work is that it has been designed with the specific intention of recovering faulty systems. Previous works have often involved reconfiguration by shifting the system to a degraded mode, discarding faulty components, which can result in the inability to fully achieve the objective. This paper introduces a constraint programming method that enables the system to adapt its parameters to new situations and continue operating. Furthermore, the paper includes a case study that describes a SoS composed of intelligent autonomous vehicles (IAVs) and a gantry crane, which was studied in scenarios where a degraded mode of operation was addressed.

• Effect of Classroom Chair Designs to the Comfort of Students: a Case of a Private Higher Education Institution  
  by Matthew Hendric Chua, Alfonso Gabriel Claros, Cedric Jared Niu, James Florence Santos, Miriam Bongo 
  Abstract: As educational institutions strive to provide proper classroom design that can satisfactorily support the overall academic performance of students, several challenges in performance-influencing factors remain evident. Among such factors, the design of the chairs is the most pressing, considering that the other factors already have a standard protocol to be followed to ensure a conducive environment for students. Along this line, this paper seeks to explore the relationship between chair dimensions, anthropometric measures, posture and comfort. In order to validate the hypotheses formulated based on these relationships, a case study is conducted in a private higher education institution in the Philippines. Key results reveal a significant mismatch between chair dimensions and anthropometric measures and students' posture. Furthermore, students' comfort is also affected by chair dimensions and posture. Such results can provide a guideline to university administrators in improving the classroom design with respect to proper chair dimensions.

• MCDM Analysis for Sustainable Development and Green Growth in Manufacturing industries  
  by Gagandeep Singh Sodhi, Chandan Deep Singh, Navdeep Singh Grewal 
  Abstract: Modern production revolves around five key objectives: quality, cost-effectiveness, timely delivery, continuous improvement, and adaptability. Traditionally, companies achieved these goals through various practices. These include integrating design and manufacturing (often called concurrent engineering) for faster development, implementing quality improvement methodologies like Six Sigma to minimise errors, and streamlining changeovers (setup reduction) to increase responsiveness. However, emerging trends suggest a new path: fostering innovation across high-tech production facilities, with a strong focus on environmental responsibility. This approach acknowledges the critical role factories play in a company's success by directly impacting product quality and the resulting competitive edge. Ultimately, this translates into tangible benefits like increased sales due to superior offerings, a loyal customer base built on satisfaction, a larger market share driven by sales and customer loyalty, improved profitability through efficiency, and opportunities for growth and expansion fuelled by healthy profits. To truly outpace competitors, a company's operations need a strategic advantage derived from prioritised goals. This research focuses on identifying high-impact risk factors within the industry to develop a qualitative model based on their severity and potential consequences.

• Chimp Water Wave Optimisation Enabled Random Multimodal Deep Learning for Text summarisation  
  by Rajesh Kumar Cherukuri, Sampath A. K, Manoj L. Bangare, Sanjay Nakharu Prasad Kumar 
  Abstract: Text summarisation is the process of compressing longer documents into a shorter version without losing their overall information contents. However, automatic text summarisation is still a challenging issue due to the unavailability of the corpus. To overcome the issues, a robust summarisation model, named chimp water wave optimisation-based random multimodal deep learning (ChWWO-based RMDL) method is developed for text summarisation. Here, the bidirectional encoder representations from transformers (BERT) tokenisation is accomplished for performing the tokenisation operation. With the tokens, aspect term extraction (ATE) is done to improve the summarisation performance. The RMDL model is employed for the text summarisation process where the developed ChWWO algorithm is utilised for training the RMDL model. However, the devised ChWWO is the integration of the chimp optimisation algorithm (ChOA) and water wave optimisation (WWO). The developed method achieved superior performance with a higher precision of 0.961, recall of 0.971, and F-measure of 0.966, respectively.

• GSDO: Golden Search Dingo Optimisation Enabled CNN Based Long Short Term Memory with Review Vectorisation for Fake News Detection  
  by Steni Mol T. S, Sreeja P. S 
  Abstract: Fake news detection is a significant chore, which not only guarantees that users deliver authentic information, but also assists in maintaining trustworthy ecosystems. Most of the present detection approaches concentrate on identifying signs from contents of news that are commonly not efficient because fake news is oftentimes purposely written to mislead users by imitating actual news. Presently, the detection of fake news is commonly classified as social context-based learning and news content-based learning. Here CNN_LSTM_GSDO, which is an efficient technique, is designed for fake news detection. Initially, input review data is fed to the review vectorisation phase. WordNet2vec and BERT are the two models utilised in the review vectorisation stage. Finally, fake news detection is performed using CNN-based LSTM, which is a transfer learning approach. It is trained by a newly devised GSDO, which is a combination of GSO and DOX.

• Bottleneck-Based Decomposition Method for Throughput Estimation of Nonhomogeneous Production Lines with Unreliable Machines and Finite Buffers  
  by Hatice Guner, Alper Murat, Ratna Chinnam 
  Abstract: The paper presents a decomposition method for the throughput evaluation of long serial production lines with non-homogeneous machines separated by finite buffers. The machines have very different processing times and exponential failures and repairs. Even though existing analytical methods provide quite accurate results, they may have challenges in terms of both the computational effort and accuracy when the reliability parameters and processing rates are of different magnitude. To enhance the computational efficiency and reduce the complexity of the decomposition of long lines, we strategically aggregate the production line segments depending on the position of bottleneck machines and represent the long production lines with shorter throughput equivalent ones. Besides, we use generalised exponential distribution for the repair time distributions of the pseudo-machines and develop the decomposition equations. The performance of the proposed method is compared with widely used decomposition methods and simulation using extensive experiments on real-world datasets from the body shops of an automotive OEM. The findings indicate that the proposed algorithm provides highly effective solutions for analysing the throughput of long unbalanced lines.

  by Berihun Bizuneh, Belay Abera 
  Abstract: This paper aims to identify, screen, and rank the supply chain risks, and their sources in the apparel industry in Ethiopia. Data were collected from 20 experts and 392 professionals in 13 companies based on pairwise comparisons and a questionnaire-based survey respectively. The fuzzy Delphi method and fuzzy analytic hierarchy process (AHP) were used to screen and rank the supply chain risks respectively. A descriptive statistic based on the mean score was used to rank the risk sources. The results showed that supply, operational, and infrastructural risks were the top three risk categories. The major sub-supply chain risks included supplier uncertainty, technology, security of resources, safety and security, raw material and product quality, delays in production, and transportation risks. All of the identified sources of the risks were rated at least as significant factors by the respondents. Some mitigation strategies mainly focusing on supply chain collaborations were also proposed.

• Chaotic Functions Influenced Spider Monkey Optimisation Algorithm for Optimal Routing and Channel Assignment  
  by Vijay Omprakash Rathi, Raj Thaneeghaivel 
  Abstract: This paper intends to introduce a novel routing and channel assignment in multi-channel MANET. Here, the optimal routing is performed by selecting the cluster head under certain constraints like delay, distance, QoS, RSSI, and security. For this, chaotic functions influenced spider monkey optimisation (CFISMO) algorithm is used. The assignment of channels as the scheduling policy is introduced through senders while it has packets to transmit. In this work, the channel assignment will be initiated via a machine learning model that predicts the availability of the channels, which is based on the paths (channels) generated under the selected cluster head. Here, an optimised neural network (NN) will be used. Thus, the final output shows the paths (channels) to be assigned for data transmission. In the end, the performance of the adopted routing approach is evaluated over other traditional schemes based on various metrics like distance, PDR, delay, energy, alive nodes, QoS, security, and trust, respectively.

• Self Adaptive Meta Heuristic Model for Floor Planning in Very Large Scale Integration  
  by Bhavya A. B, Vinay Kumar S. B 
  Abstract: The process of designing very large scale integrated (VLSI) circuits includes a stage known as floor planning. Floor planning is done to ascertain the relative location of the various modules inside each sub-circuit after the complex circuit is divided into smaller sub-circuits during the partitioning stage. The objectives of this process are to minimise the total chip area covered by the circuit, the amount of dead space in the layout, and the interlinking wire length (WL) among modules. Estimating the placements and forms of the modules is what it is all about. The integrated circuit (IC), which has small feature sizes, a high clock frequency, and high packing density, can dissipate a lot of heat. This work proposes a self-adaptive cat swarm optimisation (SA-CSO) to resolve the floor plan issues. The non-slicing floorplans are regarded by the algorithm as having hard modules with continuous outline restraint. Thus, the area of layout gets reduced.

• Residual Preload Prediction Software System Design for Casing Tail Nozzle Bolting System based on Elastic Interaction Stiffness Theory  
  by Wujiu Pan, Xi Li, Hengyang Xu, Yuanbin Chen, Junyi Wang, Jianwen Bao, Xianjun Zeng 
  Abstract: Bolt connection structure is widely used in aerospace parts connection, due to the influence of elastic interaction, the preload of bolt connection will change, so it is necessary to establish a prediction model for the residual preload of the bolt group. Based on the spring-node model and the elastic interaction theory, this paper designs a software system for predicting the residual preload force of the casing tail nozzle bolting system. The system is developed based on MATLAB, which reads the data entered by the user and solves for single-bolt single-step, single-bolt multi-step, and double-bolt for different preloading methods. Predicts the distribution of residual preload of a bolt group under any initial preload and tightening sequence according to different preload sequences. The software can display initial data, prediction result graphs and prediction data and export them, which greatly improves the efficiency and accuracy of preload prediction.

• Optimised NN-Based Flood Prediction on River Morphological Changes in the Ganga River  
  by Chandan Raj, Vivekanand Singh 
  Abstract: Floods have become a geo-environmental hazard, which has turned out to be a disaster as it has a destructive effect on the economy and society. Nowadays, several flood prediction systems have evolved that consider the previous flood events, from which the upcoming flood events can be predicted. This work develops a new flood prediction model on river morphological changes, particularly in the Ganga River. The suggested design is divided into two main parts: 1) feature extraction; 2) classification. At first, the input is given for the feature extraction phase, where the vegetation index features and water index features are extracted. After this, the extracted vegetation and water index features are classified, where an optimised deep neural network (DNN) is deployed. Furthermore, the DNN weights are adjusted using the self-improved lion algorithm (SI-LA) to increase the created approachs accuracy.

• Product Mix Optimisation Model for the Coconut Oil Industry  
  by Ivan Gunawan, Lusia Permata Sari Hartanti, Bernadeth T.N. Klau, Nor Chofifah 
  Abstract: Coconut can produce numerous derivatives and by-products. A coconut oil industry with five production processes: expeller-pressing, refinery, extraction, hydrogenation, and pelletizing can produce up to 11 products. A product mix problem often arises in the determination of the quantity of each product to be produced. As such, product mix decisions can significantly affect profit generation. This research aims to develop a mathematical model based on Linear Programming (LP) to maximize profits. The optimization model developed in this study estimates that the industry can increase profits by 43.9% by applying the best product mix decision. A sensitivity analysis shows that changes in capacity affect the model. Three production flow scenarios were tested in the LP model. Scenario 1 (adding Refinery 2, using it like Refinery 1 plus using Refinery 2 to produce refined bleached deodorized hydrogenized coconut oil super) can increase the industry's profit by 28%.

• Streamlining Internal Logistics in the Automotive Industry: a Simulation-Based Optimisation Framework within Lean Production  
  by Yongzhong Wu, Qianyu Zhang, Yuxiang Wu 
  Abstract: Lean production principles have been extensively adopted in the automotive industry, primarily targeting the minimisation of inventory levels and cycle times. However, as the industry confronts fierce competition and evolving demands, internal logistics costs within factories have emerged as a significant portion of total operational expenses. The complexity of internal logistics is further compounded by the involvement of multiple resources and intricate processes. This paper introduces a simulation-based optimisation approach designed to streamline internal logistics, focusing on minimising resource utilisation across various processes while adhering to constraints on work-in-progress (WIP) levels and cycle times. The proposed methodology was successfully implemented in a component supplier within the automotive sector, yielding an 814% improvement in resource utilisation and a 12% reduction in annual logistics costs. These findings underscore the potential of simulation optimisation to enhance operational efficiency and lower internal logistics costs in complex lean production environments.

• Construction of Prediction Model for Individual Investors’ Psychology and Behavior Based on Cognitive Neuroscience  
  by Guangdong Liu, Sang Fu, Shiyong Liu 
  Abstract: Traditional forecasting models cannot extract the trend information of retail investors' multi-scale psychological and behavioural data, and the predictions are not accurate. To solve this problem, a Markov-based individual investor psychology and behaviour prediction model is proposed. Using the wavelet multi-scale analysis method , the multi-scale data of individual investor's psychology and behaviour are extracted. A long-term-memory analysis is performed on multi-scale data of individual investors’ psychology and behaviour using the correlation analysis method, and the trend information is extracted. On this basis, a Markov prediction model is established, and a modified investment preference model is introduced to improve the accuracy of the prediction. Using the individual similarity degree, the nearest neighbour set of the target individual is established, and a multi-order predictive Markov fusion model for multiple individuals is formed to achieve accurate prediction. The experimental results show that the proposed model achieves better nonlinear fitting and higher prediction accuracy.
