摘要巖體隨機不連續面三維網路模擬技術成熟與否的一個重要標志就是最終的網路模型是否能夠較真實地再現巖體的實際情況，為了使三維網路模型的結果能夠真正地應用於實際工程，就必須對模擬的結果進行必要的檢驗，檢驗的辦法就是將模擬出的模型剖面圖形與原型測量窗口的圖形進行圖形對比，或者將原型的觀測數據與模型的測試數據進行數據對比，當這種檢驗達到精度時，模擬出的模型為有效模型，可以投入工程實際應用。 -

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 -
