摘要
针对时间Petri网现有强、弱语义模型在调度分析上存在的缺陷以及凝练调度一致性问题和调度时限性问题,提出混合语义模型解决方案,并给出混合语义模型的特征条件,比较混合语义模型与强、弱语义模型的时间互模拟能力,证明混合语义模型的正确性和时间行为的不可替代性。
Two time semantics,a strong semantics and a weak one,are usually adopted by time Petri nets in different application context.But they are limited in schedulability analysis because of scheduling consistency problem and scheduling timeliness problem.This paper defined two characteristic conditions for consistency and timeliness,presented a time Petri net model with mixed semantics,and proved the mixed semantics model is more suitable for the schedulability analysis of real-time systems than the existing time semantics models.We further compared the timed bisimulation ability of the mixed semantics model and the strong and weak semantics models.
