Production Efficiency Improvement by Using <i>Tecnomatix</i> Simulation Software and RPWM Line Balancing Technique: A Case Study

Abstract

One of the most used production systems is the assembly line balancing which is used to improve or balance different production line of different industries all over the world. This paper is about improving the productivity of a particular sewing line of a Duffle Trolley (DFT) bag of VIP Industries Bangladesh Private Limited by balancing the line. By balancing the line product can be produced at a high production rate in the shortest time with an optimum productive way which is also cheap and demanded quality. This paper identifies the opportunities for improvement of current sewing line by performing RPWM (Ranked Positional Weight Method) line balancing technique and testing feasibility using Tecnomatix simulation software. In this study, at first-time study of each operation was performed. For each process SMV (standard minute value), the existing line efficiency and production cycle time also labor productivity were calculated. Then using the precedence diagram and RPWM a balanced line layout was found and the line was tested by Tecnomatix software for validity. The final result obtained was an optimized and improved balance line layout for the sewing line. Finally, following this, the company will be able to produce the product at a high production rate through the minimum cost and meet the daily production target.
