【摘要】Oncean emergency event occurs, effective emergency measures should be taken. It isknown that the emergency event possesses characteristics of limited time andinformation, harmfulness, and uncertainty, and the decision makers are oftenbounded rational under uncertainty and risk. This paper presents a novelapproach to emergency decision making with hesitant fuzzy information, whichtakes regret aversion of the decision makers into account. Firstly, based onthe idea of the water-filling theory in the field of wireless communications, amathematical programming model that can convert the attribute values into acompatible scale and eliminate the influence of different physical dimensionsis constructed to determine the attribute weights. Then, a group satisfactiondegree function is introduced into the regret theory to depict thepsychological behaviors of the decision makers, based on which the perceivedutility value function of alternative is constructed. The total perceived utilityvalues of alternatives can be computed, and the ranking order of alternativesis obtained. Finally, a case study on a fire and explosion accident is given toillustrate the application of the proposed method. Besides that, thecomparisons show the feasibility and superiority of the proposed method.
