摘要
研究了软件过程的随机 petri网 (SPNs)模型及仿真分析方法 .利用SPN基本原理与描述方法 ,分别建立了软件过程基本活动SPN模型以及各种关系诸如顺序、并列、选择等的SPN模型 ;讨论了SPN模型的仿真策略 ;采用蒙特卡洛方法分析了过程系统的进度与资源冲突等问题 。
The software process SPN model and simulation analysi s were considered. Compared with the other producing process, the software process is more complex and dynamic, so the simulation analysis is essential to analyze much information such as resource conflict, process schedule and optimizing for the designed one. By using SPN basic theory and description method, the SPN mod el for basic activities of software process and their relations such as sequence , parallel and selectivity and so on are proposed, and the simulation strategies of SPN model were discussed. The schedule and resource conflict for system were analyzed by using Monte-Carlo method, and the precision of the method was disc ussed.
