Optimization Of Placing-in And Taking-out Wagon Operation Process

Railway in China's entire transportation system plays a key role, how to accelerate the pace of railway development, is currently facing a critical task. On the internal, to improve service quality, improving train running at the same time, how a more efficient, convenient, safe transportation of passengers and goods, reduce vehicle at the time, improve transport efficiency and speed up vehicle flow is also important we currently face Subject.This paper will address compression lorry at the time, and enhance transport efficiency, speed up vehicle flow at the core discussions with a view to shortening the trucks at the station at the time purposes. In addition, the content will be the focus for cargo operations on the delivery truck on the optimization problems, including best delivery vehicle for further discussion of the number of delivery vehicles, as well as summing up the sequence of optimization problem.The article has been in previous research work on the basis of the divided into several parts for cars sent to study the issue, mainly to do the following work:First of delivery vehicles at home and abroad to take the issue of the status quo, and research and to find ways to improve existing problems in order to determine the direction of the article. And then introduce the main delivery vehicle for the concept and to reduce Powered goods vehicles parked in the station when the basic method.The article's main innovation has three parts, the three parts of this paper is the focus of the content. The first is the best delivery vehicle for the improvement of the number of issues, namely the introduction of a time of the original parameters of the problem was further discussion. This was followed by targeted radiation-only lane Zhida Ju flow of vehicles to send the order to solve the problem of innovative methods, the introduction of ant algorithms to solve such problems, and on the operating table by comparison. Finally, there is uncertainty on the issue of the delivery vehicle for some uncertainty in the application of the issues into the triangular fuzzy numbers, specific issues of preliminary discussions.
