三角模糊数互补判断矩阵的一种排序方法及其在项目投资决策中的应用

A Method for Priorities of Triangular Fuzzy Number Complementary Judgment Matrices

引入Y ager第三指标将模糊数非模糊化,将专家判断矩阵中的三角模糊数转化成精确数,再利用精确数互补判断矩阵的排序方法进行排序.并通过实例说明了方法的可行性和有效性.

This paper uses the third index of Yager to transform fuzzy number into non-fuzzy number, and convert triangular fuzzy numbers in expert judgment matrixes into exact ones. Based on the exact numbers, priorities of complementary judgment matrices are provided. Finally, the feasibility and effectiveness of the method is showed by example.
