Research on optimization of integrated delivery for agricultural product production chain and marketing chain

In this study, the integrated delivery of agricultural product's production chain and marketing chain, and the optimization of integrated logistics chain are investigated. For this purpose, the vehicle routing problem with simultaneous pickup and delivery (VRPSPD) models for integrated delivery of agricultural product's production chain and marketing chain are established. Then, the established VRPSPD model is solved by Clarke-Wright (CW) algorithm. In order to confirm the effectiveness of proposed approach, the actual case that the logistics park of agricultural products in central China's Henan Province is carried out. The results indicate that the transportation cost of the integrated delivery of the agricultural product's production chain and marketing chain is significantly lower than that of the two separately.
