Abstract: Selecting emergency alternatives for emergency response with multiple states in a crowd-gathered place is worthy of being discussed in-depth and is a topic with practical application value. With respect to correlated attributes, a method for selecting emergency alternatives in a crowd-gathered place based on discrete Choquet integral is proposed. The matrix with gains or losses of alternatives with respect to multiple states of emergency response is normalized. On the premise of considering correlated attributes, an evaluation matrix is built according to discrete Choquet integral and normalized matrix. According to the probability vector of multiple states, an overall assessment expectation value of each alternative is calculated, and the optimal alternative for the present emergency problem can be determined according to the ranking result of overall assessment expectation values. A numerical example is given to illustrate the feasibility and validity of the proposed method.
