Design And Development Of Engineering Design Change System For Tianjin Highway

Now the engineering change management of highway corporation was in still uses the manual or semi-automatic method, such as word and excel for their daily work, which causes low efficiency and quality, especially in searching history documents, examination, approval and engineering change management. Therefore, I want to use network technology and information technology to optimize the design of the management of engineering change management in highway corporation. Describing a engineering change management system for work and management suitable for our highway corporation, which means a lot to the development of the informatization of daily work in the highway corporation.Through the communication with administrative management personnel and practical operation personnel in the highway corporation,I acknowledge the overall business demand of the management system for engineering change management, confirm the overall process of the system and use UML to analysis the detailed business demand of the system, obtaining the functional and nonfunctional demand of the system. Then I develop the management system of engineering change management in the highway corporation based on C/S model. The method of the development approach is from bottom to top and the technology of the development is.NET Framework, which is easy for development and deployment, high security and efficiency. MVC frame was added to the process of system design, which realizes the separation between business logic and page in the process and improves the maintenance, expansion and usability of the system. Then the system was realized and tested after the design of engineering change management system in the Highway corporation. The realization process mainly use each functional module as a unit, including realization of interface and core arithmetic of functional modules, by using C# and ADO.NET technology and SQL Server data base technology. After system realization, black box testing method is used to testify the functional modules of the system thoroughly, and then it turns out that each functional module reaches the expectation and the system is able to fulfill the operation.The system enables a clearer and more normative management process of cooperative work in the Highway corporation, saves personnel and management costs of municipal work, improves the daily working efficiency dramatically, and makes the work of engineering change management more intelligent and humanity.
