consistency ratio meaning in English
一致性比率
Examples
- 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
研究了决策信息以模糊偏好关系给出的有限方案决策问题,提出了一种简洁且实用的模糊偏好关系排序方法.该方法首先建立一个二次规划模型,然后基于该模型推导出求解模糊偏好关系排序向量的一个简洁公式.基于获得的排序向量,利用一致性比例对模糊偏好关系进行一致性检验.对于一致性较差的模糊偏好关系,则需反馈给决策者重新进行判断,直至得到一个一致性可接受的模糊偏好关系为止.最后,利用2个算例对该方法进行分析和说明,数值结果表明该方法简洁、有效,且易于在计算机上操作
