Abstract: This paper aims to reduce makespan and total weighted tardiness (TWT) by applying a cellular manufacturing system (CMS) approach based on formulations for the flowshop group-scheduling problem (FSGSP) to the sewing area of a sportswear manufacturing company in Colombia. The main contribution of this paper is the application of recent FSGSP models to a novel case study in the apparel industry. As part of the methodology, two FSGSP models framed in a CMS environment were proposed based on the literature review. In addition, a genetic algorithm (GA) was developed to evaluate this application in terms of makespan and TWT. The results showed that the proposed approach completely reduced the total tardiness penalty costs and 56.23% for makespan compared to the current state. These results seek to promote the application of models and techniques for addressing the lack of productivity, high waste, and customer dissatisfaction in this Colombian industry.
