Abstract: When multiple emergencies occur simultaneously in the railway regional network, the emergency resource reserve may be insufficient. Combining the improved analytic hierarchy process with grey clustering analysis method, the priority of rescue in multiple accident points was proposed. A multi-objective programming model for railway emergency resource dispatch was established, which had the shortest total dispatch time, the least total dispatch costs and the minimum total penalty costs (the further loss caused by the failure to meet a certain type of emergency resources). Furthermore, the priority parameters were introduced into the proposed model to obtain the emergency scheduling scheme of multiple accident points, and the problem of competition-conflict of emergency resources among railway multiple accident points at the initial rescue stage was solved. Taking the road network within the jurisdiction of a railway bureau as an example for empirical analysis, the research results show that the optimal dispatching scheme from each emergency rescue base to each accident point can be obtained by solving the multi-objective programming mathematical model with genetic algorithm, which verifies the effectiveness and scientificity of the proposed method.
