Track: Production Planning and Control

Abstract

In this work, we consider a joint model production system consisting of a single machine producing a multi-product connected to a multi-warehouse to satisfy changing and characterized customer demand of all the products and throughout the production horizon. The addition of quality control and maintenance to classical production would increase the reliability of the process, quality of the products and reduce the total cost of production due to the reduction in the non-conformal losses. The work will answer some managerial questions about which product to produce and how much each makes. Then the need for a maintenance strategy corresponding to the optimal production plan. Therefore, the production system is imperfect and subject to random failures, which directly affect quality. The system degradation is a function of use (duration) and production rate variation. The process control and product quality is with the aid of a multi-level statistical process control chart tool to simultaneously forecast the production planning with delivery quantities and the maintenance strategy involving corrective and perfect maintenance. The objective is to improve the reliability of the process, reduce the non-conformal products, thereby minimizing the total cost of production and satisfy different customers with varied random demand/Quality throughout the periods.
