Abstract
Manufacturing organizations continuously strive to improve their performance to survive in the competitive market. This study aims to improve the performance of a production line by utilizing a discrete event simulation model for manufacturing the rotor part of an electric motor. While previous studies have focused primarily on technical factors, this paper addresses the shortage of research on the impact of physical ergonomics on production line performance. By integrating human movements into other improvement methods, this study proposes four strategies: one-piece flow, elimination of unnecessary human motions, their integration, and switching to a Cellular Manufacturing System (CMS). The results demonstrate that the adoption of the one-piece flow among some workstations increases productivity and utilization of resources by about 21 % and 9 %, respectively. However, the elimination of the unnecessary motions resulted in insignificant improvement due machine’s automatic nature. Lastly, the study found that converting the production line into a CMS resulted in a significant increase in productivity (32 %), maximum resource utilization (17 %), and a decrease in work in process (40 %).

期刊介绍:
The International Journal of Simulation Modelling (IJSIMM) provides a global forum for the publication of all forms of simulation modelling research work in academic institutions, in industry or in consultancy.
The editors of the IJSIMM are searching primarily for original, high-quality, truly insightful, theoretical and application-oriented research papers dealing with simulation modelling, mainly within discrete-event simulation field in production engineering or industrial engineering.
