Improvement of Flexibility by Production Ordering Interval in Make-to-Stock Environment
Katsuhiko TAKAHASHI, Nobuto NAKAMURA
This paper studies the flexibility of production management. Especially, the effects of production ordering intervals upon the flexibility are analyzed for multi-stage production inventory systems in make-to-stock environment. After the introduction, the literature on the flexibility of production management is reviewed. A mathematical model of a production system and its management system is developed. In the model, a multi-stage production inventory system with autocorrelated product demand fluctuation is formulated. Also, the production ordering interval is considered in the production management system. As performance criteria of flexibility, the amplifications of production quantity and inventory level are analyzed, and the relationship between the prduction ordering interval and the flexibility of production management system is clarified.
