Development And Study On Railway Maintainance Management Information System

,With the market economy system reforming and operation of high-speed heavy duty train,traditional maintenance system has been not fit in the situation more and more. Computer-aided system for railroad maintenance is an effective measure to increase efficiency .Through studying the domestic and overseas relating system and considering the project of Chengdu railway bureau ,this paper discusses the method of railway maintenance management system(RMMS) development and realize in details.Firstly,based upon thoroughly researching and analyzing maintenance ,we classify statistical data. By the theory of relation database ,we establish some tentative databases including:dynamic measurement ,railway equipment,maintenance data ,etc on. At the same time ,we discuss the methods and principles of database building in detail.Secondly,according to the theory of system development,we design the function of system and embody it in every module. Some operation upon database such as edit ,query,statistic ,forecast etc have been realized. The result can be shown in three ways:grid,report table,graphic. With these functions ,workers can master the railway status very well to manage the maintenance directed against the problem.Finally,on the basis of using the experience of other countries and department for reference,the thesis brings forward some critical technologies needed in system including :forecast model. maintenance-cost model ,decision method etc. Furthermore ,we have done some preliminary work of related evaluation system.RMMS is a massive system engineering ,what we have done is just a part of it. There are still many works to do. such as establishment of evaluation system,information net,etc. We hope this thesis can throw away a brick in order to get agem.
