语言型群组决策的专家权重微调整方案

Slight Adjustment Approach for Experts' Weights of Linguistic Group Decision Making

针对语言型偏好的群组决策问题,提出一种利用专家权重微调整进行决策优选的方法.首先定义了转换函数和逆转换函数.将语言型评价通过转换函数转变为数值型,然后运用专家权重的微调整方案为专家赋权,并依据此权重利用加权和进行方案排序,最后用逆转换函数将结果转换为语言型结论.

To propose an approach of decision-making optimization by making use of expert's weight slight adjustment, aiming at the problem of group decision making of linguistic preference relation. First of all,the linguistic evaluation is transferred into numeric type by transition function;then the experts are given weights according to expert's weight slight adjustment plan, which are used for weighting and projects ranking;finally, the results are transferred into linguistic conclusions by inverse transition function.
