Comparative Study of Seru Production Systems and Traditional Assembly Lines
摘要
The implementation of the Seru production system has meant a significant improvement for several Japanese manufacturing companies. Currently, different types of Seru are identified: Divisional, Rotary and Yatai. In this study, different production metrics were compared between the assembly line and the different types of Seru. For this purpose, a worker allocation model was developed for the divisional Seru and the assembly line. Subsequently, experiments were conducted in a laboratory setup, where different production systems were implemented. Finally, simulations of these experiments were developed over a longer time horizon. From the results, a positive impact of the implementation of the different types of Seru on cycle time, throughput and in-process inventory was observed.
