Flexibility Evaluation Method of Production Systems Corresponding to Quantitative Fluctuation(<Special Issue>Manufacturing Systems Division Conference 2010)

Abstract

In the drastically changing business environments and high-paced evolution of information technologies, requirements for production become more complex and diversified around the world. Flexibility evaluation methods using life-cycle cost analysis have been developed for typical production volume fluctuations. In this paper, as a next step, the more general evaluation method is demonstrated taking a hint from the frequency characteristics of control systems; by using dynamic programming techniques the flexibility parameters are adjusted to quantitative fluctuation in order to maintain the efficiency in production system. The effect of the method is verified from the application in the production systems developed at DENSO CORPORATION.
