Abstract

For problems in multicriteria group decisionmaking MCGDM this paper defines intuitionistic interval numbers and the operational laws and comparison method of it Some intuitionistic interval information aggregation operators are proposed such as intuitionistic interval weighted arithmetic averaging operator intuitionistic interval weighted geometric averaging operator intuitionistic interval ordered weighted averaging operator intuitionistic interval heavy averaging operator and intuitionistic interval aggregating operator Then based on intuitionistic interval fuzzy information a method is developed to handle the problems in MCGDM In this method by applying the knowledge level of the experts to the decision making problem the model of maximizing comprehensive membership coefficient is constructed to determine the weights of decision makers By calculating the distances to the ideal and negative ideal solutions the comprehensive attribute values and the rank of the alternatives can be obtained Finally an example is provided to demonstrate the feasibility and effectiveness of the proposed method
