Study For Transportation Organization In HN Railway Corporation Ltd

With the rapid development of our social economy,the demand and service level for railway transportation of enterprise has new requirements.In order to meet the transport demand and solve the problems existing in the railway,such as the tight capacity,poor timeliness and so on.Railways ministry carries out a new mode of transportation organization,which is direct-connection transportation organization between enterprise and railroad.It changes the organization way of car flow of enterprise.And in the process of transport,the cost is different under various organization ways,therefore,the problem of direct-connection car flow organization needed to study.The core of the paper is to system analyze the direct-connection transportation organization,then use optimal models to research what kinds of organization scheme of car flow spending minimal time in the enterprise and the process of transportation.At the beginning of the text,I introduced much basic theories including Companies including road straight,direct transport,as well as the requirements of the operation through train and so on a series of content.,multi-level grey appraisal method.I reviewed the domestic and foreign research dynamic and literature summary to determine the basis of this article and put forward the direction of their own choice.Using the main traffic prediction method to choose the ultimate method of railway coal traffic volume forecast through the analysis of the conditions of use of prediction method and predictive ability,etc.,and give an example.This part of the thesis writing,there is no special do STH unconventional or unorthodox,but traditional classic method,is only in the aspect of data updated,will predict the timing of the extended to adapt it to the present situation of our country.In the end,according to the varieties of organization of wagon flow in loading area,this article set a linear programming model.The goal of this model is to search for a optimized way to organize the flow by the least cost,within the limit of uniqueness of wagon flow organization and the ability of technical station on the route of railway.This is the technical difficulties in full,this part of the main problems focus on operation process analysis,and transformed into mathematical form.To test paper model at the end of the article for an example,according to the above model characteristics,select the appropriate solution.The classic genetic algorithm is used in this article,and use Lingo programming to get the final optimization solution.In order to understand the further influence to the enterprise from the direct-connection transportation organization between enterprise and railroad,we add a evaluated to the implementation,and get the evaluation result.Based on the result,we find the main problems existing now and get the advices from now on.
