  • Multi-item sustainable manufacturing model for cleaner production system under imprecise demand and random defective rate   Order a copy of this article
    by Saif Sami 
    Abstract: The present study revisits the multi-item economic production quantity model by considering that production process is not perfect with the planned backorder. The present study aims to make the production system as a cleaner production system by considering a reworking process for random defective items which is uniformly distributed. In addition to this, to make the production system cleaner, an investment is made to control the production process. Based on the reworking time, two different inventory models are proposed under the effect of uncertainty in demand. Impreciseness in demand is handled by applying fuzzy set theory. Centroid method is applied to defuzzified the objective function. The global optimal solution is derived by using a nonlinear optimisation technique. Numerical analysis with sensitive analysis is provided to illustrate the proposed model. From analysis it is observed that due to increase in investment, 98% reduction in waste management cost and 11% reduction in total cost is observed. Thus, investment in system improvement is helpful to achieve the task of clean production. The study also highlighted the advantage of outsourcing for a cleaner environment. In the end, sensitivity analyses are also carried out, and based on managerial insights are provided.
    Keywords: cleaner production; rework; random defective rate; multi-item; screening process.

  • Public Procurement Reforms in The United Arab Emirates   Order a copy of this article
    by Karem Aboelazm 
    Abstract: This study deals with several concepts: centralised public procurement, decentralised public procurement, e-public procurement, and sustainable public procurement. It also explains the advantages and disadvantages of centralised and decentralised public procurement, the benefits of e-procurement in the UAE at the central and decentralised level, and its advantages in combating corruption. The study also illustrates the sustainable public procurement framework in the UAE with its three environmental, social, and economic dimensions. The study relied on descriptive and analytical approaches. It reached several results, the most important of which is that the centralised system at the federal level contributes to reducing public spending. The decentralised system contributes to the speed of meeting the needs of local administrations. It also achieved several positive results from applying the centralised and decentralised e-procurement system, which reduces corruption, and public spending on public procurement simplifies procedures and saves time and effort. The study also found that sustainability in public procurement achieves several social, economic, and environmental benefits.

  • The Role of Ethics in Public Sector Procurement Theoretical Study for Enlightenment Underpinnings of Ethics   Order a copy of this article
    by Karem Aboelazm 
    Abstract: This paper sought to present a concept of ethical behaviours in the field of public service in general and in public procurement in particular, as the issue of ethics is considered one that does not end up being addressed by literature or law. The study also attempted to identify ethical values in public procurement by reviewing the public office's most critical moral values. The descriptive approach was used to review the various definitions of ethics and values of public service. The analytical approach was also used to determine the causes and motives for the moral collapse in public procurement and the causes of deviation in this field. Some mechanisms have been found that can be used to overcome this problem, which is considered a significant challenge to public procurement systems in many countries.
    Keywords: ethics; morals; public office; public procurement.

  • Ethics in Outsourcing of Procurement: A Case Study in a Professional Services Firm   Order a copy of this article
    by Marcio Panassol, Gilmar Masiero 
    Abstract: Global economic changes have heightened competitiveness, prompting organisations to prioritise their core competencies while seeking business partners to handle non-core activities. This article presents a case study of a professional services firm that outsourced its procurement function, aiming to assess the need for and implementation of changes in its ethics and compliance program. The case study is organised into three sections: a review of relevant literature on ethics and procurement outsourcing activities, an examination of technical documents from the service firm, and interviews with three executives possessing practical experience in the field. Based on the literature review and empirical field study, it was observed that although there were appropriate changes in the firms governance structure, no substantial modifications were made to the compliance and ethical program. The study underscores the importance of considering compliance and ethical programs when implementing changes, particularly in the context of the firms governance structure.

  • Responses to Economic Challenges the preferences and reputation of market players in public procurement   Order a copy of this article
    by Gyöngyi Vörösmarty, Tunde Tatrai 
    Abstract: Market players respond to economic challenges in public procurement in various ways to improve public procurement efficiency. Securing supply to ensure stable operations requires flexibility and openness. The aim of this paper is to compare practices in the period before the coronavirus pandemic, and after the lockdowns, which was associated with economic challenges. By exploring stakeholders' perceptions of conflict, this paper analyses the changes in attitudes of contracting authorities and tenderers in terms of reputation, trust, and communication. The results show more openness to joint problem-solving and informal relations with suppliers, which requires a reassessment of the phenomena of unethical behaviour, information sharing and cooperation in procurement.

  • Scheduling of Bus Rapid Transit Station Construction Project Using Dependency Structure Matrix in India   Order a copy of this article
    by Electricwala Fatima, Rakesh Kumar 
    Abstract: The bus rapid transit station is critical in determining public transport efficiency. Uncertainties arise due to the urban arterial road layout setup, which leads to scheduling changes and delays in project completion. The secondary data were collected from two BRT stations, including project completion and cause of delay encountered. Conventional planning practices disregarded iterative and inter-disciplinary activities, leading to suboptimal scheduling, rework, and time overrun. The analytical design planning technique (ADePT) has been introduced as a planning methodology that leverages a dependency structure matrix (DSM). The DSM-based scheduling technique incorporates design activity information, iteration design process, sequential activities, and rework risk into the competing internal and cross-stage activities that give optimised schedule sequences. The developed analytical tool fits shorter schedules, overlapped tasks and validation. This study suggests that identifying overlap activities and rework time can lead to the effective use of resources for the timely completion of station construction.

  • Considering Continuous Review Policy in a Two-Echelon Inventory System using a Reinforcement Learning Approach   Order a copy of this article
    by Adele Behzad, Mohammadali Pirayesh, Mohammad Ranjbar 
    Abstract: This research focuses on analysing a two-echelon inventory system comprising a central warehouse and several identical retailers. The system utilises a continuous review policy for replenishment across all facilities. The demand at the retailers follows an independent Poisson process, and the lead times are subject to stochastic variability without a pre-defined probability distribution. Additionally, the lead time for the warehouse, sourced from an external supplier, is assumed to remain constant. Unfulfilled demand is lost at the retailers, while it is backlogged at the warehouse. To optimise the ordering points and predetermined order sizes at all echelons, a reinforcement learning algorithm is developed. The proposed algorithm's effectiveness is evaluated through simulation and comparison with existing literature solutions. Moreover, the algorithm is implemented with both ordering points and order sizes as decision variables, demonstrating the efficacy of the Q-learning algorithm in this context.
    Keywords: multi-echelon inventory system; continuous review; lost sales; reinforcement learning.

  • From Inactive to Proactive: Examining Social Sustainability Approaches and Relational Dynamics in Procurement from a Social Capital Perspective   Order a copy of this article
    by Jad E.L. Bizri, Sven-Anders Stegare 
    Abstract: This study investigates how social sustainable procurement is characterised in terms of relational dynamics and its impact on social sustainability outcomes. Adopting qualitative research with a focus on the social capital lens, 21 semi-structured interviews with 30 respondents were conducted in the Swedish hospitality sector. Our findings point towards four distinct social sustainability approaches: inactive, reactive, active, and proactive. These approaches are influenced by the relational dynamics, encompassing dialogue, goal and cultural value congruence, and frequency of interaction. The study highlights the pivotal role of dialogue as a catalyst for transitioning from an inactive to a proactive approach. This research contributes to the development of a theoretical framework rooted in social capital theory, examining how relational dynamics influence the selection of social sustainability strategies. Furthermore, it provides valuable managerial insights, offering a social sustainability-procurement trajectory model that assists managers in assessing their strategic standing and guides them to specific improvements.

  • Payment Methods and Sustainable Inventory Management in Online Business: A Comparative Analysis   Order a copy of this article
    by Manoj Kumar Sharma, Shubham Bhushan, Pragati Bhardwaj 
    Abstract: In the dynamic world of online business, the choice of payment methods plays a crucial role in shaping how inventory is managed. Firstly, cash on delivery are examined for their immediate liquidity benefits, which help in quickly turning over inventory and managing cash flow efficiently. Secondly, advance payments are analysed for their ability to offer upfront capital, thus reducing the need for extensive inventory financing. Finally, credit payments (buy-now-pay-later and EMI options) are assessed for their potential to boost sales volume and consumer purchasing power. In this study employs a demand-sensitive pricing approach and explores investments in preservation technology. The decision-making process incorporates considerations of carbon emission policies and investment of preservation technology. The primary focus is on a comparative analysis of payment schemes in the context of online inventory management. Theoretical insights are validated through numerical examples and sensitivity analyses to derive practical managerial implications.
    Keywords: e-commerce business; price sensitive demand; preservation technology; payment schemes; deterioration; carbon emission.

    by Edward Markwei Martey  
    Abstract: This paper aims to examine the antecedents of acceptance of halal food among non-Muslims in Ghana using the extended theory of planned behaviour. The study employed a judgmental sampling method to collect primary responses from customers of halal food. Questionnaires were designed based on the constructs of TPB and VEN and were distributed to 463 respondents. The gathered data were analysed using partial least squares structural equation modelling to test the hypotheses developed through literature review. The results of the data analysis indicate that only trust in halal food moderated the relationship between personal value and acceptance of halal food. This research incorporated environmental beliefs, personal norms, personal values, and pro-environmental attitude as moderating variables on the constructs of TPB, with a specific focus on non-Muslims in Ghana.

  • Perceived Uncertainty and Purchase Intention in Social Commerce: Analysis of the Moderating Role of Seller's Response Time and Returns Policy   Order a copy of this article
    by Renger Kanani, Goodluck Charles 
    Abstract: Although research on the uncertainty of online businesses has begun to attract scholarly attention, there are few studies on the effect of uncertainty on social commerce purchase intention and measures to mitigate it. To address this gap, this study examined the perceived effect of uncertainty on s-commerce purchase intention and the extent to which the seller's response time and lenient returns policy moderated buyers' perceived uncertainty. Using empirical evidence from 155 social commerce buyers, the study revealed that s-commerce purchase intention is negatively and significantly influenced by the perceived uncertainty of potential buyers. It is also revealed that the purchase intention is negatively and significantly influenced by the delayed response time, and is positively and significantly influenced by the lenient returns policy. In view of these findings, the study demonstrates that an effective response time and lenient returns policy can mitigate the effect of perceived uncertainty on s-commerce purchase intention.

  • Cost Optimization of Single Server Retrial Queue with Standby Server, Extended Vacation and Delayed Repair   Order a copy of this article
    by Poornima R, Kirupa K 
    Abstract: This paper analyses a steady-state queueing system with repeated attempts, coupled with a standby server during vacation periods. Clients arrive in batches according to a compound Poisson process. If the server is idle upon batch arrival, one client receives immediate service; the rest join the orbit. Otherwise, the entire batch joins the orbit. After each service completion, the server may take a vacation and may extend the vacation with a certain probability. During vacations of the main server, a standby server serves clients. The server is subject to breakdown at a random amount of time, and the repair starts after some delay. After repair, service resumes for interrupted clients. Using the supplementary variable method, the equilibrium condition of the system is derived, and the stochastic decomposition law is verified. The system's probabilities and performance metrics are obtained. The optimal standby rate is determined through cost analysis to minimise expenses for the proposed model.
    Keywords: batch arrival; Bernoulli extended vacation; standby server; random breakdown; delay repair; reserved time.

  • Impact of Inventory Leanness on Financial Performance of Firms with Mediating Effect of Risk-Taking   Order a copy of this article
    by Farah Naz, Amna Bashir, Veera Salman, Anam Tariq 
    Abstract: This study investigates the impact of inventory leanness on the firms’ financial performance along with the mediating role of the risk-taking decision of those firms. This study analysed 244 Pakistani firms from 2010-2020 using Panel Regression Analysis. The statistical findings show that having optimized levels of inventory boosts the financial performance of firms. Moreover, the risk-taking decision of firms partially mediates this impact. Previous contradictory findings and fewer studies examining Pakistani firms in this regard mandate this study to be carried out. The study is limited by a few factors such as a specific country under study leading to a lack of generalisability. Additionally, the impact of inventory leanness on financial performance can be hindered due to uncontrollable or systematic risk factors, making room for future research.
    Keywords: inventory leanness; financial performance; financial leverage; capital intensity; size of firm; return on assets; return on investment; empirical leanness indicator; inventory turnover.

    by Mohanbabu S, Vettriselvan R 
    Abstract: In any industry, logistics and supply chain management will play a major role in defining the strategy and competitive price. This paper aims to review existing literature on supply chain challenges and artificial intelligence involvement in logistics to overcome such challenges. The current study was carried out across various regions of India. Primary data was collected from 150 respondents who are involved in supply chain and port operations. Further, this paper focuses on examining the significance and difference of opinions among industry clusters with respect to functional roles and experience levels. Findings revealed that significance exists between various types of industries, and fuel prices influence operation costs. Finally, a data science-interlinked artificial intelligence neural network model (DSIAI) was constructed to overcome supply chain challenges and concludes that container port issues and operations also affect various industries when their efficiency decreases. The developed model provides useful insights into the logistics industry.

  • Procurement Practices and Public Sector Procurement Performance in Ghana: the Moderating Role of Political Interference   Order a copy of this article
    by Lomatey Toku, Abdul Samed, Francis Andohbaidoo, Joshua Ofori-Amanfo 
    Abstract: Scholars and practitioners have shown keen interest in understanding how procurement practices influence public sector procurement performance. More importantly, there have been inconsistent results on this phenomenon. Political interference has been noted as a potential contributing factor, especially in developing nations such as Ghana, but has not been examined in prior empirical studies. Grounded in the agency theory, we explore two mechanisms that are key in influencing public sector procurement performance: 1) procurement practice; 2) political interference. Data from 308 procurement practitioners from state institutions in Ghana were obtained using questionnaires. Smart PLS version 4 was employed to analyse the data. The outcomes confirm a positive statistically significant relationship between procurement practice and public sector procurement performance. Additionally, political interference negatively moderates the relationship between procurement practice and public sector procurement performance. The contributions to theory and practice are discussed.

    by Jugal Kishor, Swati Sharma 
    Abstract: The rich tapestry has given rise to tangible objects, such as handicrafts, which are expressions of human ability, devotion, and creativity. Many experts in the field have stressed the many advantages of handmade items, praising their beneficial effects on both society and the environment. Focusing on the promotional aspect of Indian handicraft items using different social media platforms is the purpose of this research. Recognition, perception, and product value are the three metrics that the research uses to evaluate the efficacy of social media marketing campaigns targeting handmade items. This empirical study employed a questionnaire administered offline to gather data from 386 samples, which were then analysed using structural equation modelling.

  • Procure-To-Pay(P2P) Processes: an Empirical Exploration of Inefficiencies   Order a copy of this article
    by Jonas Ronellenfitsch, Jana-Rebecca Rehse, Fareed Zandkarimi, Christoph Bode 
    Abstract: In recent years, researchers have increasingly centred their attention on strategic and tactical procurement processes. In contrast to that, procure-to-pay (P2P) processes, which operationally ensure the availability of input resources, have rarely been studied. However, industry managers know that P2P processes can be a constant source of resource consumption and compliance risks. In this research, an exploratory analysis of real-world ERP data using process mining methods shows the nature of P2P inefficiencies as well as hints regarding their origin. Four requestor-related, four item-related, and four supplier-related factors resonating with a newly developed inefficiency indicator are structurally reviewed. This study contributes to the academic discussion on information systems in operations / process management in three ways: Methodically, by introducing and testing a new measure for process inefficiency; empirically, by applying the rather novel technique of process mining to a large-scale real-world dataset; and theoretically, by exploring the character of P2P inefficiency.

  • Investigating the Impact of Logistics Practices on Marketing Performance of Business Enterprises: the Mediating Role of Competitive Strategy   Order a copy of this article
    by Arega Setegn, Gurudutta Japee, Aklilu Desta, Girma Admassie 
    Abstract: This study examines the mediated influence of competitive strategy in the relationship between logistical practices and the marketing performance of business enterprises. To choose sample respondents, purposive, and simple random sampling approaches were employed. The useable and effective questionnaires for this study included 330 responses. The survey findings were examined with SPSS version 26.0 software as well as AMOS 24, a structural equation modelling application. The study found that procurement, manufacturing support, and distribution practices had a positive impact on marketing performance. Furthermore, competitive strategy acts as a statistically significant mediator between procurement practices, manufacturing support, distribution practices, and marketing performance. Even if the findings are encouraged, their effects remain limited. To compete successfully in business and improve marketing performance, companies must ensure efficient and effective raw materials, and implement quality control procedures to ensure consistent product quality and optimise distribution channels to effectively reach their target customers.

  • Enhancing Sustainable Procurement: the Role of E-Procurement Implementation in Local Government Institutions of Ghana   Order a copy of this article
    by Abdul-Razak Imoro, Mustapha T. Seidu, Rebecca A. Boadi 
    Abstract: This study evaluates the extent of e-procurement implementation (EPI) within public procurement processes and examines its relationship with sustainable procurement performance (SPP) among local government organisations. Grounded in institutional theory (IT), this research adopts a descriptive quantitative approach, utilising a cross-sectional survey of 220 local government staff in the upper east region of Ghana. Data were analysed using descriptive statistics and multivariate regression analysis. Findings reveal that while procurement processes such as needs identification, specification of requirements and proposal evaluation are highly automated, others like contracting invoice verification and record-keeping remain predominantly manual. Additionally, EPI shows significant positive impacts on environmental impact, social responsibility, economic contribution, and ethical sourcing, with the strongest effect observed in economic contribution and the weakest in ethical sourcing. This study provides significant information for local government organisations on making informed decisions regarding EPI and highlights the importance of institutional dynamics in enhancing sustainable procurement practices aligned with broader societal goals.

  • Main Benefits of Centralised Government Procurement: an AHP Application with Brazilian Experts   Order a copy of this article
    by Stéfane Nascimento Da Silva, Alexandre Nascimento De Almeida, Celso Vila Nova De Souza Júnior 
    Abstract: Public procurement has gained strategic importance within organisations, leading to a growth in centralization models in contracting. However, the effects of these models are still discussed and evaluated to a limited extent by administrations. The objective of this study is to hierarchize the benefits of centralizing public procurement, contributing to the design and implementation of this model in different contexts. Based on a literature review, the main benefits of centralised procurement were grouped into three thematic axes: 1) economy, 2) innovation, and 3) sustainability. Afterwards, a group of 22 experts ranked the benefits using the Analytic Hierarchy Process (AHP). The findings demonstrated a strong alignment between theoretical predictions and the insights provided by the consulted experts. Overall, the centralisation of procurement was identified as a key driver of enhanced governance, fostering an environment conducive to innovation. This, in turn, contributed to improved economic efficiency and sustainability outcomes.

    by Margaret Theresé Constantaras, Pieter Gerhardus Mostert, Göran Svensson 
    Abstract: This study aimed to uncover the interrelationship between economic satisfaction, trust, commitment, and non-economic satisfaction by also considering the mediating role of trust and commitment between the satisfaction constructs in franchisee-franchisor relationships. A total of 415 South African franchisees completed a self-completion online questionnaire. The research and two rival models showed that economic satisfaction has an unequivocal influence on non-economic satisfaction and that trust and commitment mediate this effect. The findings contribute to our understanding of the interrelationships between the study constructs, specifically in franchise relationships, and offer insights to franchisors about how stronger relationships with franchisees beyond their contractual obligations could be fostered. The study contributes by validating, for the first time in a franchise context, the interrelationship linking economic satisfaction, non-economic satisfaction, trust, and commitment previously conducted in business studies and furthermore confirms the mediating role of trust and commitment on the relationship between economic and non-economic satisfaction.

  • A Green Approach to Inventory Optimisation: Strategic Investments in Preservation and Carbon Regulation Compliance   Order a copy of this article
    by Manoj Kumar Sharma, Khushi ., Shalu Chaudhary, Nimit Jain, Mukesh Kumar 
    Abstract: As the urgency to combat global warming intensifies, reducing carbon emissions and mitigating waste from product deterioration have become critical priorities. This study presents an innovative and sustainable inventory model aimed at minimising waste through strategic investments in preservation and green technologies. By focusing on maximising total system profit, the model integrates a deterministic framework that accounts for price and advertisement-dependent demand, as well as time-variant holding costs, all within the constraints of a carbon cap-and-trade regulation policy. Especially, the model allows for shortages, which are fully backlogged, providing a realistic approach to inventory management. The study's primary objective is to identify the optimal value of the total profit function. We further validate the concavity of the objective function by applying both necessary and sufficient criteria, complemented by graphical representation. At last, we have completed numerical illustrations and sensitivity analysis to assess the model's effectiveness and practical applicability.

    Abstract: The proposed research deals with that the seller is offering eco-friendly cosmetics to the consumer. In order to catch the attention of new customers, the seller is selling items at a nearby exhibition and giving away free samples of his main product during the exhibition. The main product and free sample of main product are two inventories, with actual market demand are taken into account. Exhibition, distribution of free samples of the main item and green investment all have a direct effect on product demand. In order to maximise profit of seller with respect to optimum value of selling price, green investment, cycle time and order quantity, the problem is formulated as a mathematical model. The findings indicate the exhibition and distribution of free samples of main product significantly increased sales and total profit. Numerical example and sensitivity analysis validated the model and derived the outcome and finally concluded the article with future scope of study.

  • VR and AR for optimisation of packaging sample processes in the food procurement process   Order a copy of this article
    by Nils Brehme, Nils Thomas Finger 
    Abstract: Despite increasing market challenges, procurement remains in most companies comparatively inefficient and does not leverage widely available technologies to the extent possible. Hence, this research seeks to support the digitalisation of procurement by investigating the potential of two selected technologies, namely Virtual (VR) and Augmented Reality (AR). This is done with a study on enhancing the packaging sample process in the particularly competitive food retail industry in Germany. In the context of increasing cost pressure, retailers are required to optimize and innovate procurement practices. By evaluating VR and AR as supplementary tools to traditional physical assessments, the study examines the technologies’ impact on efficiency and responsiveness. Interviews with industry experts confirm VR’s and AR's applicability across different product categories and emphasize considerable saving potentials for procurement. Considering related potentials and challenges, the technologies are best integrated as complementary solutions to established procurement methods, offering strategic advantages for sourcing operations.

  • The Association between Procurement Process, E-Procurement Deployment and Procurement Performance in an Emerging Economy   Order a copy of this article
    by Lomatey Toku, Abdul Samed, Francis Andohbaidoo 
    Abstract: Electronic procurement is critical in the reduction of procurement irregularities and inefficiencies in organisations and institutions in order to enhance value for money in the procurement process. This research is to examine the relationships between procurement process, e-procurement deployment, and procurement performance using the institutional theory as a lens. The projected model was empirically verified using primary data collected from 309 Ghanaian public organisations obligated to use the Public Procurement Act in their procurement activities. Analysis of statistics was performed using the partial least square based structural equation modelling method. The study outcomes validate that both procurement process and e-procurement deployment have a positive significant relationship with procurement performance. Further, whilst procurement process has a positive effect on e-procurement deployment, e-procurement deployment has a complementary partial mediation role between procurement process and procurement performance. For theoretical contribution, this research extends the institutional theory into the procurement literature. For practice, the findings provide insight for government practitioners and regulatory bodies to institute policies and protocols that encourage e-procurement deployments to enhance the activities of the procurement systems.

  • Optimising Inventory Model for Nonlinear Holding Cost and Nonlinear Price Dependent Split Demand with Advertising Frequency   Order a copy of this article
    by Vanjikkodi Thirumalaisamy 
    Abstract: This paper proposes an inventory model explicitly designed for perishable goods, integrating nonlinear time-dependent holding costs and diverse demand factors such as nonlinear selling prices, stock levels, and advertisement frequency. A partial backlogging approach for orders is incorporated to address shortages resulting from product deterioration. The model is meticulously formulated using partial differential equations and subsequently solved to derive the total profit function. Its primary aim is to optimize the retailer's total profit per unit of time by determining the optimal ordering quantity, optimal cycle time and the optimal selling price. Through graphical representations and numerical sensitivity analyses conducted using MATLAB, the paper demonstrates potential concavity within the model and emphasizes the importance of parameter analysis.

    by Manoj Kumar Sharma, Manisha Prajapati 
    Abstract: In this paper, we developed an inventory model for non- instantaneous deteriorating items with a green technology and advertisement dependent demand. In this model we have consider two types of investment first, preservation technology investment to reduce the deterioration rate of food items and second, green technology investment to reduce the carbon emission which helps to contribute to sustainable development goals 2 and 13. In this study we considered the two policies for regulation of carbon emission i.e., carbon taxation policy and cap-and-trade policy. The shortages and partial backlogging are also allowed in this inventory model. Additionally, we incorporated digital labelling technologies, such as barcode technology, which reduce human error and improve data accuracy, resulting in lower holding costs. These investments enhance both energy and cost efficiency. Finally, we developed numerical examples and theoretical results to validate the model.

  • Optimising Supplier Selection for Complex Defence Projects   Order a copy of this article
    by Elias Saadeh, Nabil Semaan, Moustapha El Hassan, Jihad Daba 
    Abstract: In the context of complex procurement processes, particularly in high-value industries such as military vessels acquisitions, relying on solid decision-making strategies is critical to selecting the most suitable suppliers. Addressing the problems of linguistic variables and uncertainty requires improved multi-criteria decision-making (MCDM) approaches. This paper provides a comparative analysis of the Fuzzy Technique for Order Preference by Similarity to Ideal Solution (FTOPSIS) and Fuzzy Indifference Target-based Attribute Ratio Analysis (FITARA) for group decision-making. Applying the Fuzzy Analytical Hierarchy Process (FAHP) for criteria weight aggregation, the study uncovers essential insights into the appropriate method for each military maritime vessel procurement scenario. Thus, it showcases significant differences in ranking outcomes, with FITARA displaying higher adaptability and the modified FTOPSIS maintaining stability under different settings and optimizing defence acquisitions.

    by Elias Saadeh, Moustapha El Hassan, Nabil Semaan, Jihad Daba 
    Abstract: Procurement management (PM) in the military requires rigorous planning, implementation, and monitoring. The procurement of products and services for military activities is subject to severe standards, including the federal acquisition regulation (FAR) in the USA and defence acquisition laws that assure security and safety. Given the strategic and complicated nature of decision-making in this industry, developing an adaptive project management technique is critical for ensuring optimal value, quality, and supplier support. This article conducts an in-depth investigation of supplier selection methods for public procurement in several nations, with an emphasis on high-value assets in the military and marine sectors. It emphasises the significance of reconciling operational objectives with regulatory limitations and provides a new multi-criteria decision making (MCDM) approach for assessing vendors. The methodology is demonstrated through a case study on vessel supplier selection, which includes engagement with several shipyards and stakeholders. The results show that this technique is effective at limiting risks, improving quality, and maintaining supplier support while providing an explicit and practical process for generating consistent and satisfying results.

    Abstract: Circular economy is the one of the most targeted development in which remanufacturing, recycle and reuse the materials that creates job with minimised resource used. Application of circular economy is increasing day by day for economic growth and healthy business. Government encourages the use of circular economy instead of linear economy by providing subsidies through regulations and taxes. In this paper a fuzzy economic order quantity model in circular economy is presented. Since some parameters are uncertain in nature, they are considered as triangular fuzzy number. Defuzzification is done by using graded mean integration representation method (GMIR). In this paper, ordering quantity and circularity index level are decision variables. The concavity of the average profit function is shown theoretically. The optimality of the parameters is determined analytically. It is further endorsed by numerical example with an intension to validate the proposed model. The CE gives a remarkable gain in profit, which is the focus of any industry that is concerned about environmental conservation. The financial advantage of the company is given due weight age in this model. For this, sensitivity analysis is independently carried out by deploying circular economy in inventory modelling.

  • Keynesian Beauty Contest in Morocco's Public Procurement Reform   Order a copy of this article
    by Nizare RIANE 
    Abstract: This paper examines the recent reform of Morocco's public procurement market through the lens of Keynesian beauty contest theory. The reform introduces a mechanism akin to a guessing-the-average game, where bidders attempt to estimate a reference price, which in turn impacts bidding strategies. We utilize this setup to empirically test key hypotheses within auction theory, specifically the roles of common knowledge and bounded rationality. Our findings indicate potential manipulation risks under the current rules, suggesting that a shift to a median criterion could improve robustness and reduce the likelihood of manipulation. This work contributes to the broader understanding of strategic interactions in procurement and offers a foundation for future research on improving fairness and efficiency in public contract allocation.

  • Untapped Potential in Albania's e-Procurement: Exploring the Consequences of Competition on Savings   Order a copy of this article
    by Edlira Martiri, Etion Kapedani, Teuta Xhindi 
    Abstract: This study focuses in Albania's e-procurement data from 2010 to 2023 which amounts to 5.33 Billion Euros awarded through 35,489 different contracts. To evaluate the effect that competition in public procurement has on savings the gathered data underwent segregation based on the number of offers received per tender. The metrics utilised are the amount of funds contracted; the number of tenders and finally relative savings. This research concludes that the largest amount of funds in Albania's public procurement has been awarded via procedures that attracted only one single bid, with low incurred savings. Simple linear regression is used to measure the effect that competition has on savings of public money, yielding a robust R-Square of 0.9587. This data model demonstrates an increase of 6.24% on savings when the number of bids is increased by one, concluding that Albania needs to embark on enhancing competition in public procurement.

  • Optimal Resource Allocation in Military Hospitals Using Inverse Erlang-B Models   Order a copy of this article
    by Jihad Daba, Moustapha El Hassan, Elias Saadeh 
    Abstract: Effective resource allocation is vital for procurement management, optimising assets use to meet fluctuating demands while minimising operational bottlenecks. This paper advances resource allocation strategies by employing inverse Erlang-B models, specifically applied to military hospitals. Incomplete gamma and Marcum-Q functions are used in novel computational formulations to improve accuracy across various traffic intensities. In contrast, inverse functions offer tight constraints for calculating server requirements under high load. Assuming a 5% rejection rate and an average patient stay of 1.5 days, a case study models daily military hospital ward admissions as an autoregressive process (AR(1)), projecting an average demand of 86 hospital beds, with a minimum of 79 and a maximum of 91 beds per day. The findings demonstrate the effectiveness of inverse Erlang-B models in capacity planning, providing scalable solutions for optimising resource utilisation in healthcare and industrial sectors (Gil et al., 2013; Marinkovic and Stosic, 2023a).

  • Investigating the Impact of Trade Credit Policies considering Deterioration, Quadratic Time-Stock Dependent Demand and Shortages with Partial-Logging   Order a copy of this article
    by Monika Naik, Shivkumar Sharma 
    Abstract: This study examines a warehouse model for deteriorating items with both owned and rented warehouses. It looks at how demand changes over time, stock levels, and allows for payment delays, enabling partial inventory fulfilment when there are shortages in the owned warehouse (OW). The model connects order delays to restocking times and analyses different scenarios based on payment delay options. The goal is to minimize inventory costs by determining the best restocking cycles, order sizes, and depletion points at the OW. The study includes algorithms to calculate these optimal values, helping decide whether renting a warehouse and using payment delays are worthwhile. With numerical illustration, it shows how this approach can optimise supply chain management by offering valuable managerial insights.

  • Optimising Resource Allocation Through the Blocked Agent Retried Model in Military Manufacturing   Order a copy of this article
    by Jihad Daba, Moustapha El Hassan, Elias Saadeh 
    Abstract: Modern procurement management relies heavily on efficient resource allocation, which is crucial to maximising military, healthcare, and industrial performance. The practical utility of traditional queueing models is limited because they frequently overlook the dynamic retrial behaviours of blocked agents. To overcome these constraints, this paper presents the Extended Erlang-B (EEB) model, which incorporates a retrial dispatching mechanism. A new iterative approach was implemented to validate the EEB, and after 22 rounds, it converged to a steady-state traffic intensity of 15.8 Erlangs. Retrial techniques have been demonstrated to boost the utilisation of resources by 60% in practical situations. Dimensioning tables provide actionable insights for designing scalable systems for different retrial probabilities. The EEB model is pivotal for modern industrial and military applications, offering superior flexibility, accuracy, and robustness in resource allocation. Compared to traditional models, it effectively addresses dynamic operational demands across diverse domains, enhancing system performance and adaptability.

  • Fuzzy Production Inventory Model for Deteriorating Items Defuzzified by Signed Distance Method   Order a copy of this article
    by S.K. Indrajitsingha, S.K. Sahu, P.K. Jena, Padmanava Samanta 
    Abstract: The research analyses a production inventory model of deteriorating items with shortages under partial backlogging in a crisp and fuzzy environment. Uncertainties play a vital role in developing a real-life inventory model. Since the system parameters such as demand, deterioration, holding cost, etc. are uncertain, so they are considered triangular fuzzy numbers. The model is developed both in a crisp and fuzzy approach. The signed distance method is used for defuzzification. The concavity test of the total profit function is shown graphically using the Mathematica 11.1 software. The objective of this model is to maximise the profit. A comparison of results in both cases is carried out to decide which method gives a more accurate outcome. The numerical example, managerial implications and sensitivity analysis are presented for the proposed model.

  • An Integrated Inventory Model for Time-Varying Demand: Balancing Trade Credit, Pricing, and Sustainability Under Carbon Tax Policies   Order a copy of this article
    by Manoj Kumar Sharma, Sakshi Pant, Paras Jhaldiyal, Neha Rani 
    Abstract: This study proposes an integrated inventory model for perishable items with time-varying demand, where demand depends on dynamic pricing and trade credit incentives. The framework addresses delayed deterioration - spoilage initiating after a predefined latency period, typical in products like seasonal produce or pharmaceuticals. To reconcile profitability and sustainability, the model integrates preservation technology investments to curb post-latency decay and carbon tax mechanisms penalising waste-driven emissions. It balances the trade-off between extended credit terms (boosting demand but increasing opportunity costs) and preservation costs (reducing waste but raising expenses). A profit-maximising function is formulated, validated numerically, and analysed for parameter sensitivity. Results demonstrate that synchronising pricing, credit periods, and preservation investments optimises profitability while ensuring regulatory compliance. The study provides actionable insights for designing inventory systems that harmonise financial efficiency with environmental stewardship under carbon taxation.

    by ShivamKrishn Agrawal, Pooja Gupta, Vijay Kumar Jain 
    Abstract: Indias rapid digital transformation has triggered a surge in digital arrest scams, with victims losing 120.30 crore in early 2024 (PMF IAS, 2025). This study employs interpretive structural modelling (ISM) and MICMAC analysis to identify 14 systemic drivers including organised crime networks, weak legal frameworks, rapid digitalisation, and psychological manipulation through expert consultations with cybersecurity and media professionals. The ISM model reveals hierarchical interdependencies: foundational enablers (e.g., jurisdictional challenges, anonymity tools) facilitate mid-tier vulnerabilities like low digital literacy and manipulative tactics, culminating in fear-driven victimisation and social stigma. MICMAC analysis classifies variables into independent drivers (systemic corruption, inadequate enforcement) and dependent outcomes, highlighting multi-level intervention needs. Policy imperatives include modernising cyber laws, expanding digital literacy campaigns, fostering cross-border law enforcement collaboration, and strengthening public-private partnerships to dismantle transnational cybercrime networks. By addressing systemic vulnerabilities and societal resilience gaps, this research provides a structural roadmap for safeguarding India s evolving digital ecosystem.

    by Anisha Mishra, Waleed M. Alahdal, Najib H. S. Farhan, Shayuti Mohamed Adnan 
    Abstract: This study explored the effect of environmental, social and governance (ESG) performance on the financial performance of Indian firms, with audit committee independence serving as a moderating variable. Utilizing quantitative methods and secondary data, the study analysed 91 Indian firms from 2018 to 2022. The research drew upon legitimacy, and agency theories, employing random and fixed effect panel data modelling for analysis. The findings indicate that ESG performance and its components have no impact on FP (measured by ROA), while ESG performance and individual performance of Environmental and Governance has a negative and significant impact on the financial performance (measured by Tobin’s Q), whereas the social performance has no impact on TQ. Moreover, the independent audit committee does not moderate the relationship between ESGP and its components and firm performance. Overall, this study is novel within the Indian context. It enhances the understanding that ESG performance has a negative or negligible impact on financial performance. This relationship is so strong that even an independent audit committee cannot moderate it.

  • Three decades of research on earnings management - a bibliometric literature review   Order a copy of this article
    by Charlotte Haugland Sundkvist, Dag Øivind Madsen, Ziaul Haque Munim, Tonny Stenheim 
    Abstract: This study uses a bibliometric approach to analyse the evolution of research on earnings management, an influential topic in accounting research that emerged during the 1980s. We extracted data from the Scopus and Web of Science databases, covering the period from 1987 to 2021. The extracted bibliography data were analysed using the Biblioshiny tool in RStudio software. We performed two types of analyses: 1) citation-based bibliometric analysis of influential journals, authors, articles, and countries; 2) longitudinal mapping of the evolution of earning management research. Themes related to IFRS, corporate governance, and variations across institutional/regulatory environments are identified through bibliographic coupling. Further, we identify and discuss several directions for future research on earnings management.
    Keywords: earnings management; financial accounting; scientometrics; Biblioshiny; literature review.

    by Manigandan Raman, Geetha Krishnan, Naga Venkata Raghuram Jeedigunta, Pulidindi Venugopal 
    Abstract: This study aims to investigate the impact of lean manufacturing practices (LMP) on environmental performance (EP) in the food processing industry in South India, with the moderating role of innovation culture (IC). This study assesses how lean manufacturing practices implementation, emphasising waste reduction and process optimisation, influences the environmental footprint of food processing operations. The study conceptual model is based on diffusion innovation theory. The data was collected from owners and managers. The data was collected through a structured questionnaire survey of 265 food processing industries located in south India. the descriptive analysis through SPSS and hypothesis testing through SmartPLS. additionally, this study performed process macro analysis and IPMA analysis. The results indicate that lean manufacturing practices positively influence environmental performance. Innovation culture positively moderates the relationship between lean manufacturing practices on environmental performance. Findings aim to provide insights into the interplay between LPM, IC and EP, providing valuable implications for practitioners, policymakers, and academics striving to enhance sustainability practices in the dynamic landscape of South India's food processing industry.
    Keywords: lean manufacturing practices; innovation culture; environmental performance; PLS-SEM.

  • Procurement and predictions: analysing crude palm oil markets in India using GARCH approach   Order a copy of this article
    by R. Supriya, Rajesh Mamilla 
    Abstract: This research investigates volatility and price discovery in India's crude palm oil (CPO) spot and futures markets, using the GARCH (1, 1) model to analyse data from the multi commodity exchange (MCX) from April 2018 to March 2022, a period impacted by COVID-19. The study reveals a strong, long-term interconnection between the spot and futures markets, characterised by error correction mechanisms. A significant finding is the R_FUTURE variable's major influence on market volatility through its impact on conditional variance. These results are vital for stakeholders like market participants, policymakers, and researchers, offering insights into the commodity market dynamics in India during a global crisis, and aiding in informed decision-making and policy development in commodity markets.
    Keywords: volatility transmission; long-term relationship; price discovery; GARCH model; crude palm oil; CPO; spot and futures; India.

  • Competition, savings, and accountability: a study of Albania's public procurement of services   Order a copy of this article
    by Edlira Martiri, Etion Kapedani 
    Abstract: This study examines the evolution of competition in Albania's public procurement of services sector from 2010 to 2022, utilising quantitative analysis of data from the Public Procurement Agency. Key indicators, such as average bids per tender, funding allocations, contract numbers, disqualified bids, and single vs. multiple bid contracts have been assessed. The research reveals a concerning 45% decline in bid competition over the study period, despite increased funding and contracts, posing challenges to cost-effectiveness. The prevalence of single-bid contracts exacerbates this issue. Importantly, the study highlights a direct link between competition levels and cost savings in services procurement. To enhance transparency and efficiency, future research should investigate the factors contributing to this decline, aiding policymakers in fostering a fair and sustainable procurement ecosystem, promoting economic growth and equity.
    Keywords: public procurement; competition trends; services procurement; Albania; Western Balkans; transparency; integrity; savings; sustainable growth; economic development; bid competition; policy impact; procurement legislation; resource allocation; accountability.

  • Enhancing high-tech exports: harnessing logistics efficiency and sustainable development goals through a moderated mediation approach   Order a copy of this article
    by Mahmoud Ramadan Barakat, Ahmed Hussein Ali 
    Abstract: Drawing on transaction cost theory and knowledge-based view, this research aims to investigate the impact of logistics performance on high-tech industries' exports (HTEX) through SDG-9.B. In addition, it tests the moderating effect of SDG-9.5 on the indirect association between logistics performance and HTEX through SDG-9.B. Data were collected from the World Bank, covering 168 countries from 2007 to 2018. Using a mediation and moderated mediation analysis techniques, results revealed that the logistics performance index (LPI) as a proxy of logistics performance could positively affect medium and high-tech industries manufacturing (MHTI) as a proxy for SDG-9.B; MHTI significantly mediates the relationship between LPI and HTEX. Furthermore, research and development as a proxy for SDG-9.5 can significantly moderate the indirect relationship between the LPI and HTEX through MHTI. This research will help extend global supply chain literature, through focusing on LPI and exports while using international data.
    Keywords: logistics performance index; LPI; Sustainable Development Goal 9; medium and high-tech industries; high-tech industry exports; panel data.
