基于效用值的直觉梯形模糊数多属性决策方法

Multiple Attribute Decision Making Method Based on Utility Values of Intuitionistic Trapezoidal Fuzzy Numbers

定义了直觉梯形模糊数的隶属函数、非隶属函数的效用值以及总效用值和精确效用值,给出一种利用总效用值和精确效用值对直觉梯形模糊数进行排序的方法,提出了基于效用值的直觉梯形模糊数多属性决策方法,并通过实例说明决策方法的可行性.

The concepts of utility values of membership function,non-membership function and total utility values and exact utility values of intuitionistic trapezoidal fuzzy numbers were defined,and then the ranking method for intuitionistic trapezoidal fuzzy numbers based on total utility values and exact utility values was put forward.Lastly,decision making method of intuitionistic trapezoidal fuzzy numbers based on utility values was proposed,and an applied example was used to illustrate the effectiveness of the proposed method.
