Economic Benefit Calculation System Designing For High-speed Railway

With greater power has been granted to railway companies, economic benefits of rolling-stocks has been paid more and more attention. On the one hand, as a large number of rolling-stocks have been put into use, a more effective method need to be designed. On the other hand, as a significant factor of economic benefit,the technique of liquidation at present, which is mainly finished by manual calculation, cannot meet the practical demand and needs to be improved with urgency. Therefore, it is of great significance to improve working efficiency, set appropriate fare rate and determine the direction of optimization. In this paper, based on the cost calculation technique, characteristics of train operations and connections among trains, a system of liquidation of rolling-stocks’economic benefits has been designed, in which all trains have been divided into groups with different rolling-stock circulation units.The following things have been included in this paper:(1) analyzing the economic benefits of rolling-stocks, determining the cost composition and calculation method based on activity-based costing and elaborating calculating formulas of other indicators; (2) analyzing the demands of system, including business functional needs, system information requirements and the demands of system interface and performance; (3) designing four function modules of the system based on the demand analysis, including basic data management, circulation data management, circulation cost calculation and economic indicators display, and finishing the system database design; (4) designing the process and algorithm for the three technical difficulties, which include circulation data input, circulation establishment and circulation cluster; (5) providing a demo with the use of the system.In this paper, using the rolling-stock circulation as a basic calculation unit, a system of liquidation of rolling-stocks’economic benefits has been designed. For the sake of the system, a useful tool of calculating the indicators including costs and profits of rolling-stock operation has been provided which meet the demand of railway companies to a great extent.
