Through an analysis of the characteristics of the Agricultural Products Logistics and its influence on the vehicle scheduling, this paper is to describe the vehicle routes whose vehicle number is uncertain and which are with time windows, to establish a distribution route optimization model which is effected by the cost and has a time limitation, to solve the model with the Compound Optimum Model Particle Swarm Optimization, and to compare it through some case. The optimization model of Agricultural Products Logistics has good practical value on reduce the cost of agricultural products logistics and improve the efficiency of logistics distribution of agricultural products.
