OPTIMAL CONTROL OF A DETERIORATING PRODUCTION PROCESS
Abstract:We study the optimal control of a production process subject to a deterministicdrift and to random shocks. The process mean is observable at discrete points of time after producing a batch and, at each such point, a decision is made whether to reset the process mean to some initial value or to continue with the production. The objective is to find the initial setting of the process mean and the resetting time that minimizes the expected average cost per unit time. It is shown that the optimal control policy is of a control limit type. An algorithm for finding the optimal control parameters is presented.
Keywords:Deteriorating production process  Taguchi's loss function  Process control  Quality control  On-line information  Optimal stopping
