摘要:

根据直觉模糊多属性决策的特征,引进反应决策者风险态度的风险参数,构造融决策者风险态度、得分函数和精确函数为一体的综合得分函数,并依据综合得分函数得到一种排序直觉模糊数的新方法,再结合直觉模糊加权平均算子提出一种属性值为直觉模糊数的多属性决策方法,并通过算例说明该决策方法的可行性和有效性.

Abstract:

Based on the feature of intuitionistic fuzzy multiattribute decision-making, a mentality parameter is introduced to mirror decision maker's mentality, and a comprehensive score function is proposed, which unified the decision maker's attitude, score function and accuracy function into an index. Besides, a ranking method for intuitionistic fuzzy numbers is proposed based on the comprehensive score function. Furthermore,a multi-attribute decision method based on intuitionistic fuzzy environment is developed in combining with the intuitionistic fuzzy weighted average operator. Finally, a numerical example is given to illustrate the feasibility and effectiveness of the new method.
