Method of Fuzzy Multiple Attribute Decision-making Based on Interval Fuzzy Number
Abstract: Interval fuzzy Numbers, as a tool to solve the problem of decision making, and it can describe the decision making information clearly. While discussing the fuzzy multiple attribute decision making problems of interval fuzzy number that attribute values, first the decision matrix use the proportion of change law to standard, standardization and weighted matrix and sorting, we introduce the advantage of rough set relationship to scheduling problem with multiple attribute decision-making object in this paper, selecting the best answer. The last case tests the validity of the optimal strategy to solve specific problems.
Key words: Interval Fuzzy Number; Multiple Attribute Decision Making; The Proportion of Change Law; Sorting
