Research On Drawing Up Methodology Of Cooperative Train Working Diagram And Route Allocation Plan For High Speed Railway

High speed railway, comparing to conventional railway, has the operating characteristics of high speed and high density, aiming at providing passengers with high quality service. Therefore, a more accurate and reliable train diagram is needed to conduct train operation. Train route allocation plan at stations is an important extension of train diagram, and has an intimate interaction relationship with train diagram. Study on integrated scheduling theory and method of the two problems will improve the quality of train diagram and helps to serve passengers better. For this reason, the research has a certain practical significance.This study carries on research on integrated scheduling of train diagram and train route allocation plan on the basis of a large number of relevant literatures. It analyses the interaction relationship of train diagram and train route allocation plan, which provides the theoretical basis of collaborative programming of the two. Using synergetics theory, this study analyses the systematic characteristics of high-speed railway operation system, and gets a strategy of optimization method of train scheduling and train route allocation. Appling on the optimizing strategy, the research develops the formulation and arithmetic of train diagram and train scheduling on stations. By solving the real-world problem, the research gets the result of train diagram programming and train scheduling on stations considering relative optimizing factors of train operation in sections and on stations. The main work is presented as follows:1. This paper expounds the connotation and characteristic of high-speed railway train diagram and train route allocation plan. It analyses the interaction relationship between the two problems from the aspects of fundamentals, influential factor of motor train unit, spatial organization of solution and reactive mechanism of action. The theoretical feasibility of integrated programming train diagram and train route allocation plan synergistically is proved.2. This paper analyses system characteristics of high-speed railway operation system, showing that the system runs in the shape of train flow. Train flow of high-speed railway system is classified as ordered state and disordered state under synergetics. It defines the controlling on resources in train operation system of train diagram and train scheduling on stations as the slaving affects, instructs of system as order parameters, and creates order parameter equation. It summarizes the optimization strategy of integrated scheduling of train diagram and train route allocation plan, idealizes the method of optimizing the scheduling of high-speed train operation synergistically on basis of synergetics.3. This paper puts forward the attributive characters of grain flow, including essential attributes of train flow, interval attributes of train flow, station properties of train flow, train properties of train flow and corresponding impact on position order of train flow. It proposes an algorithm of train flow order, and takes the result as the decision basis of optimizing synergism of train diagram and train route allocation plan.4. This paper builds the "full timetable" in the context of programming statement, known as model of train diagram which maximizes the number of trains. Meanwhile, a heuristic algorithm of train diagram and train route allocation plan is designed on basis of state transition. Take the result of best utilizing train diagram on this level as the basic result of optimizing collaborative problem. Create optimizing collaborative model route allocation plan, and seek the best solution of train diagram and train route allocation plan on basis of basic result using general state transition adjustment algorithm.
