Abstract

Abstract: To improve rescue efficiency and quality of the emergency response process, risk perception of different types of victims and the efficiency of emergency bottleneck resources need to be considered in research regarding the emergency resource scheduling problem, thereby a reasonable scheduling scheme can be formulated. Firstly, the emergency response stages and types of victims were subdivided, and the emergency resources scheduling problem was described from three aspects: resource environment, task constraints and optimization objectives. Next, the Prospect Theory (PT) was used to characterize the victims' behaviors and construct the risk perception function, and then the 0-1 nonlinear multi-objective integer programming model was established. Furthermore, genetic algorithm was used to simulate the problem, and the computational results were portrayed by Pareto and sensitivity analysis. The results show that in emergency resource scheduling process, considering the risk perception of different types of victims and the efficiency of emergency bottleneck resources can help to reduce victims' risk perception and improve the rescue efficiency and decision-making quality.

Key words: optimal scheduling, system efficiency, integer programming model, emergency bottleneck resources, risk perception
