摘要

The green supply chain management (GSCM) has been paid much attention worldwide, and with increasing government regulation and stronger public awareness in environment conscious, enterprises have become more responsible for their products to reduce pollution and damage to the environment. Among issues of GSCM, green supplier selection is a critical problem as a first step to improve environmental performances since a good supplier helps to supply materials that comply with international regulations. That is, to adopt a comprehensive green supplier selection procedure to choose the appropriate suppliers can keep the manufacturer competence in the market competitive. The purpose of this thesis is to develop a green supplier selection procedure which will take both traditional and environmental criteria into account. We take advantage of ELECTRE III which allows analyzing different types of criteria without converting them into a single scale. It also has the characteristic of non-compensatory and considers the situations of incomparability and indifference, which makes the ranking result even truly reflect the DMs’ opinion. To overcome the limitations of the method, we develop it into a Two-Phase ELECTRE III method, and with the result, suitable green suppliers are recommended to the DMs. In this thesis, we provide a more useful result by making good use of the discrimination threshold, which haven’t been discussed in the previous studies. In the illustrative example, we also obtain the weights provided by the analytic hierarchy process (AHP) method. We compiled a brief summarize of the advantages and disadvantages of ELECTRE III method and AHP method respectively to show that the favorable characteristics of determinations of weights of the AHP method could enhance ELECTRE III method.

隨著環境保護意識的增加，以及國際間針對環境政策訂定各種規範，現代企業更需致力於綠化公司營運的每個層面，綠色供應鏈管理也應運而生，而綠色供應商評選更是其中需要首要考量重要的議題。過去文獻中針對傳統供應商的評選模式已臻成熟，然而較少有同時考慮供應商評選的傳統準則與環境相關準則，因此本研究同時考慮傳統與環境相關準則，並建立一個完整的綠色供應商評選程序，使得評選出的供應商在各方面都有良好表現。本研究利用 ELECTRE III法設計一個綠色供應商評選程序，利用此方法的無補償性質，使決策結果能更真實的反應決策者的觀點。再者，為了使決策過程能更加有效的區別供應商之間的表現，我們將其發展成二階段ELECTRE III法，並利用區別函數的特性進行調整。透過AHP與ELECTRE III兩模式特性上的比較，我們亦可發現AHP法在求取權重上的優勢，因此本研究的數值範例中，我們以AHP法求得權重應用在我們發展的二階段ELECTRE III法中，藉此選出最適合的數個綠色供應商供決策者參考。
