考虑能耗优化及带有时间调整的车辆路径规划研究

Research on Vehicle Routing Problem with Energy Consumption Optimization and Time Adjustment

考虑到实际装载量对物流配送过程中燃料消耗量的影响,将燃料消耗量的优化引入到配送路线规划设计中,同时本文在模型的约束条件加入调整时间这一因素更加贴合实际运作情况。最终本文建立了基于J公司实际运作情况目标函数的ECO-VRPTW模型。并使用MATLAB求解,结果表明根据J公司实际配送数据求解方案得出的平均装载率与原先对比有明显的提高,说明本文建立的模型可以有效解决其现在面临的问题,实现配送成本最低的目标。其次J公司所出现的问题也是大多数物流企业面临的问题,因此,本文的研究对其他物流公司在车辆路径配送安排上具有一定的借鉴意义。

Considering the effect of actual loading on fuel consumption in logistics distribution process,the optimization of fuel consumption is introduced into the distribution route planning and design.At the same time,the factor of adjustment time added to the constraints of the model is more suitable for actual operation.Finally,this paper establishes an ECO-VRPTW model based on the objective function of J company's actual operation and uses MATLAB to solve.The results show that the average loading rate obtained from the J company's actual distribution data solution is significantly improved compared with the original comparison,indicating that the model established in this article can effectively solve the problems it is facing and achieve the goal of the lowest distribution cost.Secondly,the problems of company J are also the problems faced by most logistics companies.Therefore,the research in this paper has certain reference significance for other logistics companies in the arrangement of vehicle route distribution.
