直觉模糊多属性的意见集中排序法

研究了属性权重信息不完全确定,属性值为直觉模糊集的多属性决策问题。首先根据直觉模糊数的得分函数和精确函数对决策矩阵中的评价值比较大小,进而按属性集中的每个属性对方案排成线性序;然后通过计算赋权模糊优先矩阵确定方案的优属度,建立规划模型确定属性的权重;再利用加权算术算子对方案集结,得到专家对方案的排序,从而得到一种新的意见集中排序的决策方法。数值实例说明该方法的有效性和实用性,可为解决直觉模糊多属性决策提供新方法

Attitudes Concentrated Order for Multiattribute Desion Making in Intuitionistic Fuzzy Set

This paper discusses an intuitionsitic fuzzy multi-attribute decision-making problem, whose weights of attribute are not entirely sure. First, we compare the size of intuitionistic fuzzy value which belongs to the decision matrix on the basis of score function and accuracy function of intuitionistic fuzzy numbers, and arrange programs in the sequence according to every property. Then we determine the weights of the attribute by calculating the weighted fuzzy preference matrix and membership degree of project. We get the ranking results of the decision makers by using arithmetic weighted method of generating. A new method of attitudes concentrated order is obtained in this paper. A numerical example is examined to show that the method proposed in this paper is effective and practical, and thus, we give a new method for solving the multiple attribute decision making problems with intuitionistic fuzzy sets.
