Track: Production Planning and Management

Abstract

The advancement of computerized technology enables us to handle the file size as large as needed and retrieval may take a split of a second as well as the interaction of several files is quite possible. Therefore, the entire manufacturing system may change. Lately, Integrated Process Planning and Scheduling (IPPS) systems are published in abundant and probably successfully implemented for various level of manufacturing scale. It seems that the previous system of Material Requirement Planning (MRP), capacity planning, production scheduling is going to disappear and IPPS system replace them. However, management insist to impose controlling factors such as delivery date and cost on IPPS systems to achieve successful execution. This paper proposes a flexibility manufacturing system and describes the tasks of each unit. The production-order section is negotiating the realistic cost and delivery due date and release jobs to IPPS and report customer inquiries on production order progress. IPSS is working as a processing system on the integration policy that a free resource searches a free operation. The proposed approach has been described with examples as well as the algorithm has been explained.
