Abstract: The second distribution of product oil is the transportation process of product oil from the depots to petrol stations and customers. It is an important link of oil product supply chain and closely related to the profit of the products oil sales enterprises. In this paper, the domestic and foreign research results on secondary distribution of product oil were investigated and the common algorithms and the latest research results of secondary distribution were detailed. It is indicated that with the development of intelligent logistics, initiative distribution will be the development trend of secondary distribution of product oil. Meanwhile, the secondary distribution of product oil is in the category of Vehicle Routing Problem (VRP), and they are similar in model establishment and solution methods. Therefore, the VRPs were analyzed so as to extract beneficial methods and apply them to the secondary distribution of product oil. Finally, the improvement and development space of secondary distribution of product oil was discussed and the suggestions on the optimization of secondary distribution of product oil were proposed.
