Study On Wagon Flow Optimizing And Planning The Technical Station Of Xiang-Shi Line

The layout of technical station guaranteed the department of rail to accomplish the transportation task efficiently. It thinks of not only the feature of recent wagon flow, but also the trend of the transportation development. In order to adapt the economical development and transportation organizing. Adjustment of layout for technical station is necessary. In the other word, when the wagon flow optimizing do not reach requirement, the layout of technical station is one of efficient way to solve problem.According to the optimization of wagon flow organizing, the author regards Xiang-shi line and interrelated technical station as a logistic system, and proofs the optimal layout of this line, at the same time, applies the method cost, the avoiding vice optimizing, the means of comparison and analysis etc. Combing area of Xiang-shi line, the author analyses the present situation and main problem. First, distance among technical station is too short to adapt the system of long tractive section. Second, angular wagon flow path is very long and wagon flow is no fairness. At last .with the local economical development, Contrary between transportation capacity and amount of traffic bring out.The paper is based on wagon flow optimizing and aimed at optimizing the layout of section station. The author conducts the logistic conception, namely, wagon flow as logistic management. According to the amount of wagon flow in 2010 and 2015, the author establishes mathematical model to optimize train formation plan, at the same time, adopts heuristic algorism to work out the schema of wagon flow. The author also uses the computation by tabulation to test the to all kind of possible planning schema of section station, and figure out the cost of transportation by the component of car flow from the viewpoint of economical evaluatioa At last, a feasible planning schema about section station of Xiang-shi line is drawn.
