System Demand Analysis And Design Of Tunnel Construction Cost Control Based On Extreme Programming

With the rapid development of economic globalization, the enterprise information management has become an important way to enhance the competitiveness of modern cnterprises.Enterprise information management system as an important part of information technology, has become the focus of competition inevitably.The information system software development with the features of keen competition and requirement diversification, has brought the enormous risk to information system's development.Especially,in the projects, it causes the development management system more and more difficult which because of the construction of the high design standards, the change of the requriment frequently and the other objective condition constraints.The lightweight method based on agile software development project to address the growing problem of information management system software development has brought new ideas.Extreme programming method as one of the most Sophisticated method of agile development obtaines the greate attention by the high flexibility.The dissertation analyzes the costs control system requirements and design the model which based on characteristics of extreme programming flexibilityof the tunnel project.Firstly, it studies exiting problems and characteristics of tunneling cost control, analyzes extreme programming requirement method advantages opposite in the tradition way. It designs extreme programming cost control development management planning.Secondly, it builds extreme programming demand module, improves the original demand method, avoids requirement exception, and introduces the Kano module thinking, explores the high-quality customer satisfication reuirement. On this basis, it analyzes the tunnel construction cost control systems architecture. It analyzes the main sectors with demand module and refines the tunneling cost control commond needs.At last, with the application of tunnel project cost control systems, it designs the overall framework of system development, based on extreme programming management planning; use Test-Driven Development, Simple Design extreme programming theorys and Power Designer tools to design the module according to the common requirement,and conducted empirical studies combining"China Railway Construction 18th Bureau Group Co, Ltd."...
