Abstract: The insufficient supply of refined oil will cause that the oil gas stationcan't fully meet the orders. How to arrange the reasonable distribution of limited oil is essential to ensure the safety of energy supply. To this end, the distribution priority of different customers under limited supply is considered, distribution planning, vehicle scheduling, path optimization and other oil distribution network planning activities are carried out, in-depth study on the Multiple Depot Vehicle Routing Problem (MDVRP) with multi-oil supply constraints is conducted. Firstly, a multi-objective optimization model of vehicle routing for multi-oil products and multi-oil depots is constructed, which considers the priority of demand and the cost of distribution. Secondly, the Multi-Objective Particle Swarm Optimization (MOPSO) is used to solve the model to achieve efficient vehicle scheduling and oil distribution routing optimization. Finally, based on the data information of CNPC in some oil depots and fueling stations in Qingdao, an oil distribution network is constructed for empirical testing. The results of the example show that the Pareto optimal set is generated after the optimization of vehicle routing, the distribution cost is significantly reduced, and the delivery satisfaction rate is significantly improved, which further verifies the feasibility and effectiveness of the model and related algorithms.The model and algorithm can be further extended to various supply and demand situations, which is helpful to solve the distribution problem of refined oil products with different priority of gas stations.
