摘要
针对决策准则值为模糊数、准则和决策者权重信息均不完全的群体多准则决策问题,从两两方案之间的优劣程度大小入手,拓展PROMETHEE方法中优先函数,分别建立了单个决策者下的方案准则集成、群体决策者偏好及其总体风险态度集成等模糊规划优化模型,得到训练集中各方案完全排序。通过算例表明该算法可行,其结论具有较高的可信度。
Aiming at group multi-criteria decision making with fuzzy evaluation and incomplete information of criteria＇s weight and decision-maker＇weights, the preference functions within PROMETHEE method is expanded embarking on the degree size between every pairs of alternatives. Fuzzy programming optimizing models are constructed to integrate the multi-criteria under single decision-maker and the group decision-makers ＇ preference and the whole attitude to risk. The ranking of the whole alternatives is obtained. The example reveales that the group multi-criteria decision making method is available and the obtained conclusion is creditable.
