基于可能度的三角模糊数互补判断矩阵排序方法

Study on Priority Method for Triangular Fuzzy Number Complementary Judgment Matrix Based on Possibility Degree

研究了决策信息为三角模糊数形式给出的互补判断矩阵排序问题。根据三角模糊数互相比较的可能度公式,提出一种基于可能度的三角模糊数互补判断矩阵的排序方法。该方法思路清晰、合理,计算简洁,易于上机实现。最后算例分析表明,该方法是可行、有效的。

The priority method of complementary judgment matrix is studied, in which the preference information is provided by the decision makers by means of triangular fuzzy number judgment matrix. According to the possibility degree formula for the comparison between two triangular fuzzy numbers, a possibility-based for priorities of triangular fuzzy number complementary judgment matrix is presented. The method is characterized by simple and reasonable, operation, and is easy to implement on computer. Finally, a numerical example is given to show feasibility and effectiveness of the developed method.
