Research On The Model Of Intelligent Decision-making System For Local Wagons Flow Make-up Shunting

Shunting is an important part of railway transportation, and is a technical, high requested and complicated decision working link of station. Efficient and speedy shunting operation is significant on guaranteeing the smooth work of stations and keeping a good running order for railway network. As a sub-system of railway intelligent transportation system, intelligent decision-making system for shunting work is a key means to realize intelligent shunting decision-making. Local wagons flow make-up shunting , which faces to the local wagons flow, is specially complicated. Realizing decision-making process is an important part of intelligent decision-making system for shunting work.This paper makes a detailed classification on shunting operation. By analyzing the characters and organization methods of local wagons flow make-up shunting, the thesis discuss the theories of decision-making for it. The modelings between "Connection position" and "Elimination of inverse-order" are introduced. Based on studying their individual essences for modeling formation, a law is put forward to wok out the minutes per trip. The paper proposed a optimization method , so as to improve efficiency of shunting.On the basis of the analysis for the relation between shunting operation and loading and unloading, the essay discusses the necessity for the cooperation of both schedules. The inner relation for the shunting and formation operation during every phase is studied and considered, and a mathematic model to estimate operation volume and hours is established. The essay also puts forward the principles and methods on reasonably dividing operation stages and train make-up shunting batch number under the constraints in different time, and describes the process of intelligently classifying shunting control batch numbers and operation stages by cases study.According to program step, the structure and function of the system is diagnosed, then the process of realizing the system is planned, the development of software is discussed at the end.
