A NEW METHOD FOR FUZZY MULTIPLE ATTRIBUTES GROUP DECISION-MAKING BASED ON THE ARITHMETIC OPERATIONS OF INTERVAL TYPE-2 FUZZY SETS

摘要

In this paper, we present a new method for handling fuzzy multiple attributes group decision-making problems based on the ranking values of interval type-2 fuzzy sets. The proposed method provides us a useful way to handle fuzzy multiple attributes group decision-making problems in a more flexible and more intelligent manner due to the fact that it uses interval type-2 fuzzy sets rather than traditional type-1 fuzzy sets to represent the evaluating values and the weights of attributes.
