1 應用多狀語意直接評估與整合於產品策略導向之供應績效 計畫編號: NSC 95-2221-E-236-015 執行期間: 95/08/01~96/07/31 計畫主持人:王瑞琛 東南技術學院工業管理系 教授 摘要 由於供應績效為涵蓋過去、現在與未來的 持續性動態行為,因此具有不同程度的不確定 性,故以量化的方式進行評估並不十分恰當, 有鑑於此,本研究乃透過語意變數取代數值變 數,以彌補量化的不精確性,同時依據供應行 為的特性,使用合適的語意尺度進行評估,以 提高模式的適用性,再將不同尺度之語意資訊 進行一致化轉換,最後透過熵值最大化之語意 順序加權平均運算子,將資訊直接以語意型態 進行整合,同時將產品策略導入整合模式中, 使評估結果能夠符合企業需求,進而以語意方 式模擬人類的心智決策過程。 關鍵字:供應績效、語意變數、多狀語意資訊、 模糊語意量子、語意順序加權平均運 算子、產品生命週期 Abstract Supply performance has the active continuity behaviors which cover the past, present and future of time horizons. Thus, supply performance possesses distinct uncertainty on individual behavior, which is inadequate to assess with quantification. This study utilizes the linguistic variable instead of numerical variable to offset the inaccuracy on quantification, and employs the fitting linguistic scale in accordance with the characteristic of supply behavior to enhance the applicability. Furthermore, the uniformity is introduced to transform the linguistic information uniformly from the different scales. Finally, the linguistic ordered weighted averaging operator with maximal entropy applies in direct to aggregate the combination of linguistic information and product strategy to ensure the assessment results meeting the enterprise requirements, and then to emulate mental decision making in humans by the linguistic manner. Keywords : Supply performance; linguistic variable; multi-granularity linguistic information; fuzzy linguistic quantifier; linguistic ordered weighted averaging operator; product life cycle 1. 前言 成功實施供應鏈制度的關鍵因素,在於藉 由完善的供應績效評估,以落實供應商管理機 制,因此供應績效的評估成效,攸關供應鏈制 度的成敗,而供應績效的優劣,則透過實際供 應行為呈現。在現今以市場導向與國際競爭的 經營環境下,企業必須迅速針對產品定位 (Aitken, Childerhouse and Towill, 2003) 與市場 反應 (Lee, 2003) 擬定因應策略,進而延伸出相 對應之供應鏈策略,並同步反映於供應績效所 評估屬性之準則中 (Carbonara, Giannoccaro and Pontrandolfo, 2002) 。由於供應績效評估所涉及 的層面與範圍甚廣,無法僅以區區少數的屬性 與行為進行評估,再者,因不同屬性間供應行 為特徵之差異,使得評估過程難以在同一尺度
