Abstract: With the advantage of low cost and high innovation level, Open Source Design (OSD) has become an effective way to provide diverse products with high customer satisfaction by open group intelligence. Based on literatures and best practice of the successful OSD communities, this paper classified open source community into three types: open source hardware, public investment, and personality customization. According to the process analysis of these three kinds of communities, various operation mechanisms are investigated and presented respectively. The classification and the operation mechanisms proposed in this paper can help OSD community to make rational decision in their software development process, as well as to improve the outcome and innovation efficiency of the communities.

Abstract: 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.

Abstract: In order to simulate the impact of organizational strategy on production cell, agent model of workers was developed and integrated into the production model. An agent-based human-machine collabrative simulation method for production cells was proposed. Structure and modeling steps of the simulation were studied, the proposed simulation method was applied in a motorcycle engine box production cell, and the system performance under the two different organizational strategies ‘specialized division of labor’ and ‘multi-skill team’ was compared. The results indicate that the agent-based simulation method can simulate the organizational strategy in production cells, and provide a new way to study affecting mechanism of different organizational strategies on prodution cells.
