| Summary: | 碩士 === 國立臺北大學 === 統計學系 === 99 === Supplier selection method has become a systematic decision making process with consideration of a variety of vendor attributes, as it is getting important to purchasing strategy and company’s competitiveness to get an effective and quick decision making process. In view of this, a global supplier chain management structure is proposed through the different levels of entirety purchase activities. This management structure separates the supplier evaluation of purchasing activity into two stages. The first is advanced suppliers qualification audit of their process compliance, and the second is the supplier quarter delivery score review, such as delivery, quality, and price flexibility.
Based on the audit and quarterly delivery score indices, a two-stage supplier evaluation could be practiced. At the first stage, the DEA-BCC model is applied to measure the technical efficiency of supplier’s process performance. And at the second stage, process performance and quarterly delivery performance are combined to assign the supplier chain into four perspectives, which include high process performance/high quarterly score, high process performance/low quarterly score, low process performance/high quarterly score, and low process performance/low quarterly score.
In addition, a logistic regression model is adopted to investigate the influence factors of supplier performance. The results reveal that supplier location, product quality, price flexibility and cycle time have significant correlation with supplier performance. Based on the conclusion of this research, the cost benefit of this two-stage supplier performance evaluation can be evaluated by quality loss cost and price flexibility. The practical example of this study shows that the group of high process performance/high quarterly score suppliers would be expected to reduce the cost about US$2,571,708,530 comparing to the group of low process performance/low quarterly score suppliers.
