Abstract

In order to ensure the rationality of group decision-making in the problem of deciding the location of emergency rescue facilities, it is essential to fully consider the uncertainty of post-disaster uncertainties, the multiple attribute group decision making problem with mixed evaluation value, introduce fuzzy set theory, extend the improved TOPSIS method to the fuzzy environment and propose a group decision-making method for emergency rescue facility location based on fuzzy TOPSIS. Since for emergency multi-attribute decision making problem, the accurate value is too fuzzy to simulate real life situations. Therefore, the triangular fuzzy number and linguistic variables are used to make the evaluation decision. In addition, the general weights of decision makers and the attributes of alternatives are obtained respectively based on deviation measurement method. Finally, the feasibility and effectiveness of the proposed method are verified by a specific example. The results show that the proposed method is in line with the actual decision-making mechanism.
