针对属性值为模糊变量,属性权重完全未知但已知方案优先序的模糊多属性决策问题给出一种新的决策方法。该方法通过建立一个线性目标规划模型来确定属性的权重,再基于简单加权平均法则来计算各方案的模糊综合属性值,然后根据比较模糊变量大小的期望值方法对方案进行排序。最后给出了应用实例。 A new decision-making method is proposed for fuzzy multi-attribute decision-making with attribute values ​​as fuzzy variables and attribute weights as unknown but known prioritized schemes. This method establishes a linear target programming model to determine the weight of attributes, then calculates the fuzzy comprehensive attribute values ​​of each scheme based on the simple weighted average rule, and then sorts the schemes according to the expected value method of comparing fuzzy variable size. Finally, the application example is given.
