基于冲突主体不确定证据融合的灰靶决策方法

研究基于冲突利益主体不完全确定权重信息情景下的群决策方法.把不完全确定的权重信息作为证据,建立了所有证据之间的距离最小测算模型,提出了不完全确定权重数值上、下限范围估计模型;为解决冲突证据的融合问题,提出了基于证据相似性的证据协调加权因子;建立了基于灰靶决策的靶心距分布范围确定模型,以排定方案优劣顺序.最后基于该方法探讨了某棕地开发方案的评价应用.

Grey target decision method based on uncertain evidence aggregation under conflict interest participants

A aggregation method of incomplete weight information on criteria under conflict group is suggested.Firstly,a minimum evidence distance calculation model among all evidence is proposed when the weight of criteria is taken as evidence.Then the upper and lower weight values under the incomplete information are estimated based on the minimum evidence distance.Furthermore,the weight factor of evidence aggregation is defined to solve the problem of conflict evidence aggregation.The extension method on grey target decision is suggested,which estimates the possible target distribution range of each alternative.Finally,the alternative evaluation on brown-field redevelopment is discussed.
