The Designing And Realization About The Management Information System Of Ground Duty Cycle-Overhaul

The informationization of the railway has become a inevitable trend. The informationization degree of the locomotive depot directly influences the informationization process of the whole railway. So, it is of vital importance to apply information technology to the locomotive overhaul processing. Thus, it can utilize the data to predict future, utilize information and model to aid decision, and also realize its controlling goal and behavior.Using the method of software engineering, this paper is based on the concrete condition of Xiangbei groud duty workshop and completes the analysis and design process of the cycle-overhaul MIS.The paper are divided into six chapters, the process of the whole development of the cycle-overhaul MIS has been systemically introduced.The first chapter firstly introduced the concept of the cycle-overhaul MIS, analyzed the present situation of the domestic and foreign development and told the purpose and the significance of the system development briefly.The second chapter mainly introduced the collectivity frame of the locomotive cycle-overhaul MIS, analyzed and perfected the operation flow of the locomotive cycle-overhaul. Finally the paper list the network architecture design proposal of the system unified the actual situation of locomotive depot.The third chapter mainly has made the detailedly introduction to each module functional design of the system.The system strictly follows the module division principle, then using graph tool(pane chart,Warnier,IPO chart) assistantly described the function module of the system.The forth chapter which is the hard-core part of the paper introduced the development and realization of the system, a systematic and reasonable solving project is brought forward based on frontal specific analysis. It includes framework, exploration tools, platform of software and hardware, supportive database background and structure of the network. The part of database design introduces the database exploration process of the locomotive cycle-overhaul MIS in detail. Firstly, the paper made the demand analysis of the database,according to the demand analysis which made, then using the E-R chart design method carries on the conceptual model design; Then the transform of concept model and entity-relation model is realized, the latter one must be standardized to ensure the integrity of the database. Finally, design of physical model as well as running and maintenance of the database is the last step. Moreover,the paper introduced the design process of the cyclical plan dynamic table...
