企業經營環境不斷變遷的時代，全球化迫使企業面臨更多的競爭與挑戰。採購是企業活動中最主要的功能之一，尤其採購支出約佔總製造成本60%以上，在全球化經營環境中，企業經營人員與學術研究人員均認為採購部門平時作業面臨最大管理決策便是供應商績效評估與選擇。
供應商評選過程包含許多準則且充滿複雜性，除了傳統財務指標之外，製造業近幾年來對於非財務性指標更加重視並花費時間關注，因此企業對有效供應商管理方法與工具需求更為殷切。本研究目的希望建立客觀供應商評選模式，使用資料包絡法（DEA）分析供應商績效，採用品質、製程能力、無誤訂單與交貨績效為投入項，滿意度為產出項評估個案公司14家原物料供應商相對效率，發現DMU11與DMU13為學習標竿供應商(Benchmarking)。
利用交叉效率指標分析供應商間效率變異程度。供應商效率評估結果發現可將供應商分成3類：A類供應商為特優供應商，效率最佳且效率變異最少；B類優質供應商為效率中等且效率變異不大；C類供應商為待觀察供應商，效率較差且效率變異大，進行供應商數目刪減時應從此類供應商著手。
評估結果提供給管理決策人員做為管理供應商數目參考，以達到有效管理供應商數目，減少企業經營管理成本提升競爭力。

In the era of continuously changing environment of business management, globalization has been forcing enterprises to face the increasing competition and challenge. Procurement is one of the most essential enterprise activities, especially the purchasing’s share which represents approximately over 60% of total manufacture cost. In the globalization of trade, both the business management personnels and the academic research members consider that the supplier evaluation and selection is the most significant managerial decision in the daily work in the procurement department.
The supplier evaluation and selection process includes multi-criteria decision making problems, and hence is full of complexity. Therefore, corporations are keen on the need to have the effective supplier management methods and tools. Besides the traditional financial indicators, the manufacturing industry has been paying more attention to and more concerns on the non-financial indicators for the past few years. In this research we established an objective supplier selection model which applies DEA to analyze the supplier performance. It exploits the cross efficiency index to analyze the efficiency variance among suppliers.
The outcome of the evaluation provides the managerial decision makers the reference to manage the quantity of the supplier so as to reach effective management in the quantity of the suppliers, and to decrease the cost in business management, and to provide competitiveness.
