关键重要型多属性消错决策方法

Method for Error-Eliminating Multiple Attribute Decision Making with Key-Important Attributes

针对属性为关键重要型的多属性决策问题,利用消错理论提出一种新型的决策方法.首先,依据消错理论给出错误、错误极限损失值、关键重要型属性等概念;接着,根据多属性决策问题的特征给出判断属性值错误与否的规则;再接着,通过建立错误函数计算属性错误值,并依据错误值确定可行策略集;然后,利用消错离心法对可行策略进行排序与选优.最后,通过将所提出的新型决策方法与其他方法相比较,以说明其科学性和可行性.

A new decision making approach on the base of error-eliminating theory is proposed by focusing on multiple attribute decision making [MADM] problems with key- important attributes. Firstly, the concepts of error, maximum error-loss value, and key- important attribute are given on the base of error-eliminating theory. Secondly, the rules which are used to judge whether an attribute value is error or not is given according to the character of MADM problem. And then, error functions which is used to computed attribute error value are built, and the set of feasible strategies is determined by error values. At last, the alternative strategies are prioritized and selected by the way of error-eliminating centrifugation. A case study shows that the proposed method is feasible and reasonable.
