Research Of Software Process Model Base On ATC System

Software process technology is the key to support software development, project management and quality guarantee. Through description, run, control, measurement and evolvement of particular process model, it guides and controls users'actual software process and becomes one of the research emphases of software project field. As one important part of Software process technology,It's apparent that how important the choice of software model is. With the spread of real-time system application, the complexity and development scale of software increase. Meanwhile, due to the high speed, security and robustness required by real-time system, the development of real-time system faces new challenges. In additional, the limitation comes from many factors, such as development environment, resources and time, etc., leads to the fact that current mature model is unable to satisfy the requirement of real-time system. Thereby, it's urgent to development suitable process model according to the characters of real-time system. Through much research on process model, this paper advances a process model of real-time system, in which the software life cycle of real-time system is improved and the software life cycle development process of real-time system driven by test is presented. According to different level, the development process is partitioned to guarantee the development quality of real-time system. Through researches on the extension of UML's metamodel and profile and the formalization of model, we can make UML more flexible and comprehensible to overcome its shortcomings and satisfy the needs of process model language. Based on activities and process module modeling methods, a real-time system process model is developed, which not only clearly reflects the workflow, but also improves the extent of process model's being used again. Lastly, combined the process model method of real-time system mentioned above and the characters of ATC,an instance of ATC process model are developed. By using this process model to effectively manage and control the development process, satisfying result can be acquired.
