摘要: 定义一类模糊时间Petri网用于模拟受时间约束的实时系统行为,通过对模糊时间区间的知识推理,研究实时系统中带时间因素的冲突问题和时间-空间的冲撞问题,将时间约束和冲撞发生的概率用于冲突消解。实例分析表明,相对于已有冲突分析和消解方法,该方法同时考虑了带有不确定性时间的系统冲突和冲撞行为,可以更好地模拟和分析现实中的实时系统。

Abstract: This paper defines a kind of Fuzzy Time Petri Nets(FTPN) to simulate the behavior of real-time system limited by time. It studies the conflict with time attribute and space-time collision in real-time system and utilizes time constraints property and the collision probability to resolve the conflict through knowledge reasoning of fuzzy time interval. Compared with existing methods of conflict analysis and resolution, it takes into account the uncertainty of the time with the system of conflict and contact behavior, to better simulate and analyze real-time system in reality.

Key words: Fuzzy Time Petri Nets(FTPN), conflict detection, conflict resolution, real-time system
