正态模糊数型多属性决策模型及其应用
Multi-Attribute Decision Making Model of Normal Fuzzy Number and Its Application
摘要
Abstract
Based on the standardized ideal solution and the similarity,it proposes a method for some multi-attribute decision making problems,where the information on the attribute weights is unknown (completely or partly unknown), and the attribute values and the subjective preference values are expressed in the form of normal fuzzy numbers. At first,the similarity between fuzzy numbers,the expected values and variance of fuzzy numbers and other concepts are given,and an optimization model based on the maximization of the similarity is established and solved,from which the optimal weights are obtained. Then the standardized ideal solution is acquired. Based on the similarity between each scheme and the ideal solution, all schemes are ranked. Finally,an example analysis shows that the method is feasible and effective.关键词
