摘要


隨著全球暖化議題延燒,2003年起歐盟與環保先進國家紛紛針對關鍵環境議題宣布各種規範,對於高度出口導向的台灣科技產業,國際環保法規更是直接影響企業經營型態。為避免外銷遭受綠色貿易障礙、同時維持企業形象與品牌價值,各產業面對全球綠色衝擊必須從傳統的供應鏈模式轉化成綠色供應鏈模式,方能維持企業競爭力。其中,「評選最適合之綠色供應商」更是影響企業綠色形象的顯著關鍵,亦影響該產業未來發展。本研究主要在探討台灣平面顯示器產業中,TFT-LCD製造領導廠商A公司之綠色供應商評選的問題。以A公司綠色供應商評選問題為例,藉由文獻探討與深度訪談法,瞭解該企業所採用的評選流程與供應商稽核評比內容,同時考量傳統與環境準則下,進而分析其評選準則層級架構。經由多屬性決策方法(MADM)中的層級分析法(AHP)決定各評選準則相對權重,再採用選擇轉換本質法(ELECTRE III)定義供應商的優先順序。讓決策者利用此方法非完全補償的特性,更有效區別供應商的表現,最終將取得符合企業需求的供應商評選參考排序結果,並透過分析進而了解各供應商待改善構面,作為供應商輔導標的與方向。採用此整合性方法,不僅可將企業複雜決策思維過程模型化,使得評選問題架構更清楚;且具備一致性檢定的過程,提供決策者具體且精確的證據。對於不同策略型產品的供應商配置,可藉由ELECTRE III方法求取方案優勢排序,瞭解供應商於各準則之競爭優劣勢資訊,是一個符合TFT-LCD產業或其他相關產業中長期需求的綠色供應商評選程序,可協助企業在有限的時間與資源下,有效遴選契合企業競爭策略的廠商,發揮企業競爭優勢。

With growing worldwide awareness of environment consciousness, European Union (EU) has released some environmental directives since 2003. The execution of these directives has driven Taiwan’s electronics industry to take some environmental specifications into account when managing their supply chains. To benefit from the green market trend and satisfy the demand of customers, some companies in Taiwan have implemented green supply chain and established green purchasing specifications. One key factor for green supply chain management process is the green supplier selection. This study examines green supplier selection and management where multiple attribute decision making (MADM) methods are adopted to reflect various environmental performance criteria. The green supplier rating system based on AHP method and ELECTRE III method is proposed. To demonstrate the potential application, a real case of selecting polarizer supplier of TFT-LCD manufacturer A is presented. The selection processes of the proposed approach are conducted in three steps. First, we build up the supplier selection criteria by literature review and in-depth interview with the decision makers. Secondly, an AHP decision structure is constructed to evaluate the degree of importance for the selected criteria. And, the criteria weights are derived from the experts’ questionnaires. Finally, we take advantage of ELECTRE III method which has the characteristic of non-compensatory and considers the situations of incomparability and indifference. Therefore, we make the ranking result even truly reflect the decision makers’ opinion. This thesis provides a useful, practical and flexible model for companies to select the profitable green supplier. It can also be used to evaluate the strengths and weaknesses of the suppliers for TFT-LCD or related industries. In practical, decision makers can enhance their supplier management with the evaluation results depending on various managerial considerations. They could choose the appropriate suppliers to keep the manufacturer competence in the market competitive.
