The Optimization Research On The Commercial Layout Of Large Railway Stations Based On The SLP Method

Since the 21st century,China’s railway passenger transport has developed rapidly.With the continuous expansion of high-speed railway network,the volume of railway passenger transport is also growing steadily year by year.In the process of railway passenger transport,large passenger stations play an important role.A large number of passengers are gathered and distributed here,which contains huge consumption potential and provides a basis for the increase of revenue of large passenger stations.At the same time,the commercial needs of railway passengers are increasingly diversified.Therefore,the commercial layout of large passenger stations should satisfy the needs of passengers as far as possible without affecting the functions of the stations,so as to improve the service quality of passenger transport and increase the revenue of the stations.At present,the research on the optimization of commercial layout of large passenger stations in China is still relatively deficient,lacking the support of relevant theories and methods.In this paper,the problem of commercial layout of large passenger stations is studied.Combining SLP method with the actual situation of passenger stations,an optimization method of commercial layout of large passenger stations based on improved SLP is proposed,which realizes the optimization of commercial layout of large passenger stations and obtains a more reasonable optimization scheme of commercial layout.This paper mainly studies from the following aspects:(1)This paper analyses the concept and characteristics of large passenger stations and their commerce,summarizes the development status and development process of large passenger stations in China,classifies the commercial facilities of passenger stations,and analyses the commercial layout forms of different large passenger stations.(2)This paper combines the SLP method with the actual situation of passenger station,considers the flow line interference of commercial facilities,the correlation between commercial facilities and the distance traveled by passengers,constructs the optimization model of commercial layout of large passenger station,and designs the corresponding solution method by CPLEX software.(3)Taking Tianjin Railway Station as an example,this paper analyses the present situation and existing problems of the commercial layout of Tianjin Railway Station.Using the method proposed in this paper,the paper uses CPLEX software to solve the problem accurately,and optimizes the commercial layout of Tianjin Railway Station.The interference degree of the commercial facilities streamline and the distance of passengers have been reduced in the optimized layout scheme,and the correlation degree between commercial facilities has been improved.Rationality of the method.The rationality of the optimization method has been verified.(4)With the help of Anylogic,this paper constructs a simulation model of Tianjin Station’s commercial layout.By using this model,the commercial layout schemes of Tianjin Station before and after optimization are compared and analyzed,and the optimization schemes are evaluated,which verifies the advantages of the optimization scheme and further illustrates the rationality of the layout optimization method in this paper.
