Grain logistics vehicle routing problem is a kind of combination NP-hard problem. According to the large batch and multi-point to multi-point transportation of grain logistics, this paper considers vehicle routing problem with time windows and its intelligent algorithm. An algorithm of PSO for VRPTW is proposed in this work, experiments are made to compare the algorithm with GA on solving this problem. The experimental results indicate that algorithm of PSO will be an effective and feasible approach for grain logistics VRPTM, and reduce distribution cost.
