| Summary: | 碩士 === 中原大學 === 工業與系統工程研究所 === 99 === The demand for electronic product market changes frequently; therefore, equipment manufacturers must be flexible enough to meet market demand and their operation status affects not only the survival of their enterprises themselves but also affects the overall operation of the semiconductor supply chain. Equipment manufacturer usually sets an overall goal for the company operations, and the plant also uses performance indicators for performance evaluation. However, performance indicators sometimes failed to closely coordinate with the overall goal, in such a case, it is not effective to achieve the goal by means of the performance evaluation system.
This study aimed to develop performance evaluation system and to help the company to integrate company objectives with performance indicators. In this project, theory of constraints (TOC) was applied to find the critical problems of the manufacturing plant; furthermore, interviewing with the managers and observing the shop floor of the factory were used to understand the current problems. Four core problems were induced by using current reality tree, and analytic hierarchical process (AHP) was applied to calculate the weightings of key problems and critical to quality (CTQ) factors. Consulting with the company managers, this project integrated alternatives, and developed action plans and guidelines to solve material shortage problems.
The outcomes are first to identify major factors affecting performance indicators, to develop formulas of performance indicators, to find the causes of inefficient workflows, and to propose action plans to the company.
Key word: key performance indicator, theory of constraints, analytic hierarchical process
