成品油二次配送优化研究

Study on Optimization of Refined Oil Second Distribution

我国关于成品油物流、配送领域的优化还处于起步阶段,配送方案还存在很多问题,为了降低二次配送过程中油品的损耗,节省二次配送费用,合理的安排车型和路线具有实际意义。以分仓式大容量罐车分点装卸为例,建立合理安排车型和最短路线(TSP问题)两阶段数学模型,并采用lingo软件和遗传算法进行求解,得出合理的车型和路线安排。

China in the field of optimizing refined oil logistics and distribution is still at the initial stage,distribution plan still exists many problems.To reduce the loss of oil and save distribution costs,reasonable arrangements about routes and models during the second distribution process are very necessary.In this paper,taking sub-bunker large-capacity tanker as an example,two stages of the mathematical model for reasonable choices of vehicle types and the shortest route（tsp problem）was established,then this problem was solved by lingo software and genetic algorithm,and reasonable vehicle type and the shortest route were obtained.
