工作機械の組立における生産現場の適応メカニズムの解析

Machine tool assembly is dynamic and complex because of intrinsic uncertainties in its process. Human dependent production system is often used to deal with uncertainties, but it also increases complexity. Significant research about production scheduling has been done, but effectiveness of its application to human dependent production system is not investigated enough. In addition, not only scheduling but also other countermeasures are applied to improve production performance. This paper presents a framework to analyze how machine tool assembly system responds to supervisors' instruction. The framework includes an event driven simulation, and the simulation model is generated by the facts observed at the real machine tool assembly site. The simulation results reveal conditions which enable to improve production performance effectively at machine tool assembly site.
