考虑车辆配载率的大蒜运输路径优化研究

A Study on Garlic Transportation Route Optimization Considering Vehicle Loading Rate

将二维车辆装载与车辆路径结合起来研究新鲜大蒜的运输问题,综合考虑车辆载重利用率和非满载共配运输因素,通过一定的转换方式,将配送时间的约束转换为车辆路径的约束,达到高效的配送。研究发现:单方面考虑车辆路径情况,会导致车辆装载率下降,从而增加运输批次、降低运输效率;在满足相关约束的前提下,当车辆路径的权重大于车辆装载的权重时,表现的适应度数据和车辆路径数据更优,车辆的载重利用率和体积利用率明显提升,总行驶距离大幅减少,运输总成本显著下降。

This paper combines the two-dimensional vehicle loading and vehicle path to study the transportation problem of fresh garlic,comprehensively considers the vehicle load utilization rate and non-full load co-distribution transportation factors,and transforms the constraint of distribution time into the constraint of vehicle path through certain conversion methods,so as to achieve efficient distribution.The study found that the unilateral consideration of vehicle path will lead to the decrease of vehicle loading rate,thus increasing the transport batch and reducing the transport efficiency;Under the premise of satisfying the relevant constraints,when the weight of vehicle path is better than the weight of vehicle loading,the fitness data and volume path data are significantly improved;the total driving distance is significantly reduced;and the total transport cost is significantly decreased.
