The Study On The Optimization Method Of The Functional Area Allocation Of The High Speed Railway Passenger Station

The paper is to improve the service level of high speed railway station and reduce station internal investment as the goal, research on the configuration method of the optimization of function area of the high speed railway station and simulation evaluation,which has theoretical and practical value.First of all, by consulting the relevant data of the optimization of the domestic and foreign high-speed railway passenger station function area, the author classifies and summarizes the research results of the predecessors, and puts forward the overall research ideas and technical route. This paper analyzes the factors that affect the scale and layout of the functional area,and elaborates the specific influence of each factor on the above two aspects in detail, which lays the foundation for the functional area size and layout of the next chapter.Secondly, according to the research results of predecessors and the actual situation, using the knowledge of stochastic process and queuing theory, the calculation method of the functional area scale is determined. Then, the paper considering the passenger and investment demand, with the minimum mean passenger walking time and the minimum investment as the objective function, considering the size constraints, functional area length and width constraints, each functional area cannot overlap and streamline the design standard and the functional region of the constraints, establishing multi-objective mixed programming high speed railway station function area layout optimization model based on the matlab using improved genetic algorithm to solve the model, finally obtains the Pareto solution set.Finally, because of the lack of optimal service level as one of the goals in the multi-objective model, in order to be able to select the best solution of the service level in the Pareto solution as the configuration of the functional area of the high-speed rail passenger station.The paper based on agent simulation and anylogic simulation software, by creating a simulation environment, controlling logic module, writing related parameters and Java program, respectively to the Pareto solution scheme of two centralized typical pedestrian simulation, obtain the related index data, combined with high speed passenger service the level of evaluation model, gives two scheme of service level, and select the best service level as the final match.Compared with the traditional single objective programming and static evaluation, this paper takes more factors into consideration, which is of innovative significance. The research results can contribute to the design of high-speed railway passenger station.
