The multi-attribute group decision making in the police station evaluation system

摘要

The aim of the paper mainly study to group decision making problem in the police station performance evaluation system by utilizing interval-valued intuitionistic fuzzy soft set based on operations. In the process of the decision making, we fully consider the importance of each expert according to their knowledge background. Firstly, we introduce an interval-valued intuitionistic fuzzy soft set and their properties and operations. According to the idea of operators to aggregate the thought of different experts, and successfully apply to the mid-level soft set of intuitionistic fuzzy soft set, which confirm that "membership levels" and "non-membership levels" are entirely considered as the threshold to judge some of parameters whether can be considered as an important basis of evaluation of the final alternatives. Secondly, we apply weights of attributes in choice value of candidates to evaluate the alternatives. Finally, the paper shows a comparison with other group decision-making approach to demonstrate the accuracy and perfection of obtained result.
