An Integrated Optimization Model of Control Chart and Preventive Maintenance Policies for Non-normal Data
In this paper, we develop an integrated optimization model for control charts and preventive maintenance policies to reduce the costs associated with operating manufacturing processes. When a signable for an assignable cause is triggered, a search is initiated and the process is then brought back to an in-control state by repair. If an assignable cause is not found, the process produces products in an out-of-control state until the next sampling or warning,which occurs first. The Burr distribution is employed to conduct the economic design of ,(X)charts for non-normal data. Assuming a process with a Weibull distribution time shift and an increasing hazard rate, a generalized economic model for the joint determination of an inspection schedule, the design of the (X) control chart and the preventive maintenance policies are developed. Then the sensitivity analysis to evaluate the effects of nonnormality on the optimal design is done.
