In this paper,a vehicle scheduling model for emergency with time windows was created based on models for general logistic system,in consideration of the urgent and emergent characteristics of vehicle scheduling during the period of disasters.Two scheduling goals,minimum demand of vehicle and minimum time expense,were discussed in this model.Because general solution is hard to be obtained for this case,heuristic algorithm which could improve efficiency of solving and is applicable for computer program was discussed herein.Two heuristic algorithms based on C-W algorithm were proposed and tested with an example.The example shows that these two heuristic algorithms could get satisfactory results.
