碩士 === 元智大學 === 工業工程與管理學系 === 95 === The purpose of this study is to evaluate three epitaxial silicon wafer suppliers of a schottky diode company in order to provide a way to select the best supplier under the strong demand for silicon and further drive the suppliers to improve their overall operation performance in the supply chain. DEA (Data Envelopment Analysis) is utilized in the research to first select input and output factors based on related literature reviews and then to analyze the effectiveness of resources inputted. AHP (Analytic Hierarchy Process) is used to establish evaluation indices, including 49 items adopted from Dickson(1966) and Choi(1996) and related literature and then to be analyzed by an expert survey, which was conducted in three steps: determination of important indices, calculation of the weights and priority of each dimension and index, and compilation of the subjective opinions of experts to assign the weights and priority of level dimensions and principal factors. The results indicate that DEA is preferred to be used when the suppliers have a close level in quality, cost, delivery time and service due to its objective feature, which can select a supplier with stable managing and cooperative relationship. On the other hand, AHP is suggested for choosing the best supplier when the candidates are all distinguished for their stable managing performance.
