摘要
挂车是甩挂运输中的重要组成部分,影响整个运输系统的正常运转。挂车的投放量大,则运营维护成本、管理成本和信息系统新功能研发成本越高;挂车的投放量小,则无法满足货运量需求。文章从共享挂车视角出发研究挂车投放量问题。首先在不同的调度周期情况下构建模型,分析发现,调度周期越小,挂车的需求更小,投放规模越小。其次在不同投放比例情况下构建挂车运作成本总成本最小的共享挂车投放模型,设计启发式算法求解,通过算例测算共享挂车的投放量。结果表明,在挂车总投放量一定的前提下,挂车在场站的投放比例影响总成本。按需求比例投放有利于总成本的降低。研究为区域配置共享挂车提供前期准备。
The trailer is an important part in Drop-and-Pull transport,which affects the normal operation of the whole transport system.When the amount of trailer is large,the operation and maintenance cost,management cost and new function research and development cost of information system are higher.The small amount of trailer cannot meet the demand of freight volume.In this paper,from the perspective of shared trailer,the delivery quantity of the trailer is studied.Firstly,the model is built in different dispatching cycle.The analysis shows that the smaller the dispatching cycle is,the smaller the demand for trailers is and the smaller the delivery scale is.Secondly,the trailer delivery model with the minimum total operating cost of trailers was built to reflect the applicable delivery ratio,a heuristic algorithm was designed to solve the problem,and the amount of trailer delivery was calculated through an example.The results show that under the premise of a certain total amount of trailers,the proportion of trailers in the yard affects the total cost.Placing in proportion to demand will help reduce the total cost.The research of this paper provides preliminary preparation for regional allocation of shared trailer.
