Research on Vehicle Scheduling Problem of distribution in VMI model

Logistic distribution is an operation linking with consumer directly, and takes account for considerable proportion in variable costs in logistics. A scientific and reasonable method to vehicle scheduling is an important operation in logistic distribution. This paper attempts to take VSP in VMI as the tow core problems for further research. VSP in VMI may be looked as the stretch of the VSP above. On the VSP in VMI, this paper analyses the contribution of the optimization of logistic distribution's system. Being aimed at looking for the optimal distribution policy, this paper put delivery routing and inventory into consideration jointly, and brings forward an mathematic model and its algorithm. Consequently, results from the case proved the availability of the model and its algorithm.
