基于目标引导的软件演化过程研究

The research of goal-directed software evolution process

基于目标和环境对软件演化过程的影响,文章对目标和环境进行了分析,把目标、环境及对应的软件演化过程活动作绑定,提出了一种目标导向的软件演化过程的模型,并以此来指导建模,这样根据目标和资源就可以确定出实现该过程的行为,在文中使用通讯顺序进程CSP来描述过程的行为,对过程的资源运算、目标状态的变迁以及目标的优先关系进行了深入讨论.

Through analyzing the goal and environment of software evolution process,binding the goal,environment and corresponding software evolution process' s activities,this paper put forward a kind of goal-directed software evolution process model,and used it to guide the modeling.In this model,the guidance of modeling was the evolution goal.The process' s behavior could be identified according to the goals and resources.In this paper it described the process behavior using communication sequential process,discused the compute of process' s recourses,transit of goal's state and the priority of goal deeply.
