摘要

供應商選擇問題為供應鏈採購管理中重要的活動之一，這是因為供應商在增進公司競爭力的環節中扮演著一個很重要的角色。供應商選擇問題為一個由質性與量性因素所組成的多準則決策問題(Multiple Criteria Decision Making, MCDM)。由於經濟與環境變動迅速的緣故，在供應商選擇問題中，有許多的資訊是模糊不清的。模糊理論(Fuzzy Set Theory)提供了一個有效的工具來處理這些不確定因素。在本研究中則整合Fuzzy Technique for Order Preference by Similarity to Ideal Solution (Fuzzy TOPSIS) 法與多目標可能性線性規劃法(Multiple Objective Possibilistic Linear Programming, MOPLP)法，在價格折扣下考慮有形、無形、質性與量性的因素評估各供應商且分配最適訂購量給予各供應商。最後，以互動式方法與二階段法所組成的求解方法，來求解MOPLP法所建構的模糊型訂單分配模型。經由本研究的測試案例以及Ozgen等學者（2008）的案例可得知，使用互動式二階段法所得到求解的效果會比單純二階段法，能夠有較好的求解表現。

Supplier selection is one of the most critical activities of purchasing management in a supply chain . It is because that the suppliers play an important role in achieving corporate competition. Supplier selection is a multiple criteria decision making problem which includes both qualitative and quantitative factors. Due to economic and market are changed rapidly, most of the information is imprecise for supplier selection problem. Fortunately, fuzzy set theory is one of the effectual tools for handing ambiguous. In this study, an integration of the fuzzy technique for order preference by similarity to ideal solution ( Fuzzy TOPSIS) and the multiple objective possibilistic linear programming ( MOPLP) technique is developed to account for tangible, intangible, quantitative and qualitative factors which are used to evaluate and to define the optimum order quantities to each supplier with price discount. Finally, an integrated of an interactive approach and the two phase approach are employed to solve the order allocation model which is composed of MOPLP methodology. According to our test example and the example of Ozgen et al. (2008), it is shown that an interactive two phase approach has good performance than the conventional two phase approach .
