【Abstract】 The vehicles mode for handling mixed pickup and delivery simultaneously is studied in this paper. As each need area is amused with the characteristics of simultaneous pickup and delivery, the heuristic method of solving the problem is adopted and the solving program is developed. To improve the program and solve the course problem of the vehicles, the simulated anneal algorithm is used.更多还原
