摘要:

针对属性权重信息不完全确定且属性值为区间直觉模糊数的多属性决策问题,建立一个基于加权精确度函数的多目标线性规划模型来获取属性权重信息,然后求得每个方案的加权精确度函数,进而根据方案加权精确度函数对方案进行排序,最后通过算例分析说明该方法是有效和实用的.

Abstract:

With regard to the criteria weights with incomplete certain information and the criteria values in form of interval-valued intuitionistic fuzzy numbers in multi-criteria decision-making, a multi-objective linear programming model is constructed based on weight-accuracy function to obtain the weight information, and then the weight-accuracy function is gotten for each alternative.Furthermore, the weight-accuracy function is used to get the priorities of alternatives.Finally, an example is used to illustrate the feasibility and effectiveness of the proposed approach.
