Research On The Network To Drop And Pull Transport Vehicle Scheduling Problem Based On Scheduling Trailer

As a kind of advanced road transport organization form,Drop and pull transport may effectively reduce the waiting time cause of tractor cargo handling.Meanwhile the Drop and pull transport would improve the utilization rate of the tractor.So it plays a more and more important role in improving the level of organization of road transport,optimizing the structure of freight capacity,and facilitating the transformation on the traditional road transport to the modern logistics industry.In recent years,the pilot work of drop and pull transport is now in full swing in our country.While enjoying great achievements in drop and pull transport,the problems of vehicle scheduling increasingly come out which restricts development and promotion of benefit of drop and pull transport to a certain extent.On the research of drop and pull transport,scholars at home and abroad mainly focus on the aspects of traffic safety,organizational pattern,policies and regulations and so on.However,the research on the drop and pull transport vehicle scheduling problem remains to be perfected.In addition,there exists some potential disadvantages in the research such as the single organizational pattern,the inexact model building,single and unilateral study on single depot and so on.In order to effectively solve the related issues,the article would make a deep analysis on the organizational pattern and the vehicle scheduling features of drop and pull transport based on the application status of drop and pull transport.Meanwhile the article researches on the scheduling problem of multiple-depot network drop and pull transport vehicle and does a useful exploration in enriching the drop and pull transport theory to guide practice work.The main research works of the article are as follows:Firstily,this paper analyzed research papers in the field of drop and pull transport at home and abroad.Then a comprehensive analysis of the mode's operation and operating procedures.The paper also discusses the concept,classification and research methods of the container transportation problem of container dumping,and provides theoretical support for the later discussion.After that,this paper presents a network-type container dumping transport vehicle scheduling model,and this paper transforms the problem into a two-stage transportation scheduling system with vehicle scheduling problem and transportation balance problem combination.This paper design the corresponding genetic algorithm to solve the transportation problem.Taking a transportation company in the Yangtze River Delta as an example,the examples are analyzed and compared with the traditional container transport mode.The experimental results show that the network type can be transported by reasonable vehicle scheduling,and can play the advantages of efficient transportation.
