Abstract：Facility location is critical for failure vehicle rescuing during traffic accidents .Improper location of rescuing facilities may result in low service efficiency , unfair competition , and unequal interests between different service enterprises .Both the club-mode and the government dominated rescuing service modes are analyzed for those problems .Based on the definition of the workload equilibrium of rescuing service , the facility location model of vehicle rescuing is built up with consideration of uncertain travel time .The novel model aims to improve the operational efficiency of the rescuing facilities and balance the profits between enterprises for providing rescuing service .A hybrid coding method with three types of chromosomes and stochastic simulation technology are used , and an optimal algorithm based on genetic algorithm is designed for solving the proposed model .Lastly, a case study is used to show the effectiveness of the model and the corresponding algorithm .
