Development And Application Research Of Information System In Railway Construction Management

The large task, long period, complex involving majors and huge data is the current situation of railway construction. Based on these situations and characteristics of railway construction, to develop a construction management information system, in order to standardize work process, improve efficiency and quality of project management, help managers and policy makers to facilitate and control the project, is so necessary.This thesis firstly introduces the planning of railway construction, analyzes project management information system of railway construction home and abroad, and proposes the information demand in railway construction management in our company. Due to the multiple modules, professional span of developers, and the need of effective management in the process of railway construction management information system, therefore, the system introduces project management, establishes the sense of overall management, clears project scope, strengthens the communication, and plan person management, time management and quality management. According to the characteristics of every stage of project management, we should grasp the project starting, planning, execution, control and objectives, to ultimately achieve the project objectives and successfully delivered.Secondly, Combined with the management framework and practical demands of our company, the thesis also raises the overall demand for integrated information systems. According to the specific needs of construction management and routine office, it can be divided into integrated office, safety and quality management, schedule management and technology management, etc. It is also divided into different modules in accordance with the system function, and it proposes the functional requirements of each module.the thesis introduces the database, development language, the application of middleware and mobile clients that infers in the railway construction management information system. And then, it elaborates the concept of layered development and software architecture, and the achievement of management system framework. Later it explains management content of the system from the point of role management, institutional management, authorization management, menu management and parameter management, etc. In addition, it introduces the database server design of information system, system application servers, and system network design and so on.According to the proposed needs of the system, in the technical support of system software and hardware, through the rational construction of information system architecture, based on the unified database, it achieves hierarchical management and establish the functional modules at all levels, for the officers to use. The system is composed of safety quality management, schedule management, technology management, materials management, investment management, clean government management, construction management rules and technical regulations, daily office management, education training and information system management and other modules. Among them, the security risk source management, schedule management and integrated office use the process control techniques. It combines the actual work process and computer technology together and improves the work efficiency and quality. The system also develops the automatic archiving function. Within the set time, it can automatically package the past data and files for use in units of time storing on the server, making it easy to query, such as information briefing, monthly construction summary, daily key risk sources, the construction plans of business lines. The system takes advantage of database search techniques and makes it possible to sharing mutual inspection function for system data. To improve efficiency, grasp the situation and make full use of information system data, it develops the function of mobile clients on the base of information system. It supports Android and ios mobile client system, making it easy to query at times. Through the development of each module, it ultimately realizes the function of each module.At last, the conclusion summarizes the study results. The project management information system is an effective way to carry out project management. It plays an active role in standardizing work process, improving efficiency and quality of project management, making it easy for managers and policy makers to control and manage the project and monitoring and managing project construction. And finally it will become strong supporting means in deepening the standardized management of railway project.
