基於市場的日益競爭，客戶需求的多變與劇變，產品生命週期的縮短，以及成本改善之壓力，供應商的選擇問題，已愈來愈受產學界的重視。供應商的選擇屬於企業策略管理層次的考量，其決策過程並非結構化而係屬半結構性或非結構性的問題，因此評量供應商判凖(Criterion)無法完全依據作業性指標(Operational metrics)；另外，目前研究文獻中，既存的供應商選擇模式與方法在尋求最佳解時，多未探討供應商的選擇判凖與企業經營策略的關聯。本研究採用供應商定位矩陣(supplier positioning matrix)，提供給決策團隊與主管，做為地圖式(Map)或透鏡式(Lens)的輔助性工具並配合模糊品質機能展開(Fuzzy QFD)手法，進行系統化的決定部品別(component/assembly-based)供應商應該俱備的供應條件與能力，幫助決策者釐清經營策略與供應商選擇判凖與權重(Weight)的關聯，將市場對產品與服務的需求條件與供應商對供應品與服務的履行能力，作整合性的連結，以選擇出能滿足市場客戶所需條件之潛在供應商。本研究考慮到新(潛在)供應商可資驗證的交易記錄(proven track records)的不完整以及評估者對評估指標認知上的不確定性，因此在供應商評估階段，導入模糊因素評分法(Fuzzy factor rating system)以及模糊構面分析法(Fuzzy dimensional analysis system);至於各供應商履行供應條件的風險問題，本模式另建有提供決策主管能依據其職權以及對各供應商背景條件的瞭解與判斷，選擇出適當的風險係數作為調整決策之用，以符合主管管理職權與決策環境。而敏感性分析的建議則可讓決策主管了解其決策態度與行為對評估結果的影響。最後，本研究以3C產業之實際個案公司，套用本論文模式進行新供應商之選擇問題，從雙方互動過程與結果評估後的檢討中，得到出一些值得推敲的管理蘊涵。

Supplier/Vendor selection decision becomes increasingly important for most manufacturing firms as it helps to increased competitiveness, customer satisfaction and profitability. The supplier/vendor selection is a decision-making problem at the strategic management level that involves a semi-structured process. The majority of the existing approaches obtained their optimal solutions without considering their fits with the strategy of the firm. This study utilizes the supplier positioning matrix, modified from the product-process change matrix, and the fuzzy quality function deployment to link the capability of suppliers with the requirements of the customers to identify the strategy-aligned criteria for vendor selection in a modified re-buy situation. A fuzzy factor rating system and fuzzy dimensional analysis are then used to evaluate the potential vendors based on the type of components required by the customers. In addition, in the proposed model, the final decision-maker is given the authority to synthesize the scores of individual alternatives based on the risks of individual vendors to accommodate the differences among the vendors to the specific environment. An empirical case study is performed to demonstrate the efficacy of the proposed system and to identify the best potential vendor(s) for further negotiation and development. The results of the case study also provide interesting managerial implications.
