Abstract

<p>This paper introduces the P3D-QAP method, which extends the prioritization and machine assignment functions of pseudo periodical priority dispatching (P3D) to post-replenishment production dealing with parallel substitute machines, upper and lower limits of inventories, and no-setup-periods (i.e., operation shifts), in addition to asymmetric setup time. Here, in the past, the P3D method has been used in semiconductor assembly production systems where several hundred product mixes are produced by simultaneously using multi-type shared resources. In an evaluation using the actual production data of an automobile parts manufacturer, P3D-QAP is compared with the extended service disciplines of EDD and a goal-chasing method, as well as the company's basic rule and results. Performance measures include three points of view: due date, resource utilization, and makespan aspects. The P3D-QAP method analyzes and much improves the main issues of due date and makespan measures, while resource utilization is maintained at a high level. These effects are believed to be due to the extended mechanism and consideration of the supply-demand dynamics in the production process.</p>
