企業特定區位的優選在公司競爭和評估方面，扮演著一個關鍵性角色。選擇適當的設施地點運作，是公司成功的關鍵。由於在現實環境中，決策問題和不確定性介入的複雜性，使得決策者有時會做出模糊的評斷。本文基於語意變數權重，透過模糊層級分析法提供區位優選之模式。提出的模糊層級分析法(AHP)，呈現一個較容易的三角模糊數排列過程與獲得優勢向量。最後以例題說明了建議的層級分析法的程序。

Facility sites decision play a key role in achieving corporate competition and evaluation, select the suitable facility sites to work, with are crucial to a company' success. Due to the complexity and uncertainty involved in real world decision problems, a decision maker may sometimes feel more confident to provide fuzzy judgments than crisp comparisons. This paper proposes a structured model for evaluating the facility sites selection by analytic hierarchy process (AHP) based on linguistic variable weight. The proposed system has an extent analysis method on AHP was proposed to show an easy procedure of ranking fuzzy numbers to rank aggregate triangular fuzzy numbers, and to obtain a crisp priority vector. Finally, a numerical example illustrates the procedure of the proposed AHP.
