Optimal control of a job-shop production system: periodic versus dynamic type

Following recent work of Matsui, Yang and Miya, the authors assume that job shop production systems consist of the sales centre-with order-selection-an d the production centre-with switch-over. This paper studies on the control problem of a job-shop Production system of periodic versus dynamic type. F irst, a stochastic model of semi-dynamic type is proposed, and the two sub- objective functions: the mean accepted price and the mean operating cost, a re given. Next, a cooperative versus non-cooperative problem of sales and p roduction centres is discussed, and the non-monotonicity of optimal selecti on criteria is again found. Finally, a comparison of the alternative period ic, dynamic and semi-dynamic types is given, and the optimal structure is f ound.
