| Abstract: | Through analyze the resource requirements for expressway emergency rescue, the relationship between the emergency rescue response time and the distribution of resources is presented. Take the expressway sections for the analysis unit, the weight of section by the number of road accidents and its loss are calculated. Then, an optimal model of the greatest effectiveness of the rescue system with the cost limited is proposed. The improved greedy algorithm is adopted to solving the model, using the optimal effi... |
