Railway Dispatch Model and Solution Algorithm of Military Empty Container

The correlative variables were set and one fuzzy transport plan model was constructed based on customer preference according to the actual demand of military container railway transport system. In order to solve the above special transport problems, a genetic algorithm was applied, and the matrix coding method,fitness calculation, crossing operator, and mutation operator were designed. A simulation example about the above model and algorithm was given. The simulation result shows that the optimum dispatching scheme of the above model can be gained. The percentage of military transport punctuality is the key factor to improve the service level of freight transportation and transport guarantee efficiency.
