Research On Model And Arithmetic Of Making-up Shunting Operation Plan

This paper took the break-up and make-up shunting operation plan model and arithmetic as a research object, try to give basic support to automatic preparation of shunting operation plan through the study of the issue. The main research works are as follows:1. A breaking-up consist model was established according to the business processes of breaking-up consist with hump. With the introduction of Fuzzy Evaluation Theory, a selection model of pushing-out consist was established, which provides scientific support for the selection work of pushing-out consist. The data and information which is necessary to drawing-up break-up shunting operation plan were analyzed; furthermore, the outspread station name dictionary and track use dictionary were set up. Based on this data and information, the arithmetic of ploting shunting trip and distributing track was devised.2. Considering that how to settle problem roundly and expediently as well as to get a top-quality solution, the Filtration-Optimization-Calculation method was proposed. This method was explained in detail through such aspect: main thought, operaion step and the approach implemented by computer. Besides, the method was provided to solve the optimization problem about the shunting operation plan of district local train made-up by station sequence which is limited by the separation wagon group and the total amount of available tracks.3. An instance was used to analyze the steps to solve problem by Filtration-Optimization-Calculation method. At the same time, every optimized result of all the shunting plans was listed when P = 5. That is to say, the problem about how to optimize the shunting operation plan of district local train made-up by station sequence in which P = 5 was solved primarily.
