| Summary: | 碩士 === 國立雲林科技大學 === 工業工程與管理研究所碩士班 === 93 === Lead frame industry, like many traditional manufacturing industries, has faced a long time the difficulties of production scheduling and how to quickly responding to due day inquiry. Until now, the planning is usually conducted manually. The difficulties come from the complex shop floor constraints on capacity allocation. Meanwhile, advanced planning and scheduling system (APS) has achieved great breakthrough and accumulated many successful cases in these years. This research is to study how to implement a commercial APS in lead frame industry, from the viewpoint of a production planner. The implementation consists of four steps: (1) to build an APS model to describe the manufacturing environment, including working calendars, equipment, tool, key material, workstation, factory, and manufacturing routes; (2) to summarize the real production constraints; such as the right-left pairing parts constraint in the press operation, the setup constraints in the plating operation, and the economic production quantity constraint, as well as to develop the corresponding dispatching rules; (3) to study the data and workflow integration of APS and enterprise resource planning (ERP) system; (4) to establish key performance indicators and experiment the effectiveness of APS. According to the pilot runs, the planning result shows not only highly feasible but also effective. It can be preliminarily concluded that APS can indeed provide a good scheduling tool for production planners, and provide quick and reliable due day responding mechanism for salespersons.
