一种空间飞行器控制系统软件协同演化方法

针对空间飞行器控制系统软件在开发演化时存在管理复杂、开发过程无序、协同度低的问题，提出一种空间飞行器控制系统软件协同演化的方法。首先对软件演化过程中的演化活动、演化策略进行了分析，之后基于对软件演化活动所得到的演化路径利用有向图进行了建模并给出了其演化活动的排序，最后，对演化路径有向图中出现的并行活动和环的情况进行分析，同时给出了相适应的排序算法。基于该方法，软件演化过程得到规范，较好的解决了复杂情况下演化路径求取困难的问题。

A Collaboration Evolution Method of the Spacecraft Control System Software

Aiming at the development problems in the spacecraft control system software, including complex management, disordered development process and low-level of collaboration, a collaboration evolution method of the spacecraft control system software was proposed. Firstly, the activities and strategy of the software evolution process is defined and analyzed. After that, the strategy rules to direct the process of the spacecraft control system software evolution was established. Based on this method, the process of the software evolution could be constrained effectively, and the related participants could be coordinated as well. The development quality and efficiency of the spacecraft control system software would be increased significantly.
