We investigate the decision - making problem with a finite set of alternatives, in which the decision information takes the form of a fuzzy preference relation. we develop a simple and practical approach to obtaining the priority vector of a fuzzy preference relation. the prominent characteristic of the developed approach is that the priority vector can generally be obtained by a simple formula, which is derived from a quadratic programming model. we utilize the consistency ratio to check the consistency of fuzzy preference relation. if the fuzzy preference relation is of unacceptable consistency, then we can return it to the decision maker to reconsider structuring a new fuzzy preference relation until the fuzzy preference relation with acceptable consistency is obtained. we finally illustrate the priority approach by two numerical examples. the numerical results show that the developed approach is straightforward, effective, and can easily be performed on a computer
研究了決策信息以模糊偏好關系給出的有限方案決策問題，提出了一種簡潔且實用的模糊偏好關系排序方法.該方法首先建立一個二次規劃模型，然後基於該模型推導出求解模糊偏好關系排序向量的一個簡潔公式.基於獲得的排序向量，利用一致性比例對模糊偏好關系進行一致性檢驗.對於一致性較差的模糊偏好關系，則需反饋給決策者重新進行判斷，直至得到一個一致性可接受的模糊偏好關系為止.最後，利用2個算例對該方法進行分析和說明，數值結果表明該方法簡潔、有效，且易於在計算機上操作 -
