The performance of production cell for motorcycle engine parts is critical for the competitive capacity of motorcycle products. In order to meet the maximum beneficial result with minimum cost, simulation approach is applied to find the best improvement scheme of the production cell. Performance indicators including rate of comprehensive utilization of equipment and rate of utilization of workers are established. Two different production schemes are analyzed based on work study. Flexsim simulation software was used to simulate and evaluate the schemes. The comparative simulation results show that simulation provides an effective way to find the best improvement scheme by evaluating overall performance of the production cell, instead of partial performance evaluation by traditional work study methods.
