摘要: 模型检测技术在实时系统验证中被广泛使用。离散时间区间时序逻辑满足性是可判定的,因而也是可模型检测的。连续时间域时间区间时序逻辑是否可模型检测,则并不清楚。约束时间域到非负实数,证明了其可满足性是不可判定的,但存在该逻辑的可判定子集,并发现了这样的子集。由于模型检测问题可归约为时序逻辑满足性判定问题,因此结果表明,时间区间时序逻辑不可模型检测,但其可判定子集可模型检测。

关键词: 时间区间时序逻辑,可满足性判定,表达能力,模型检测

Abstract: Model checking is used widely in verification of real-time system. Satisfiability of discrete Timed Interval Temporal Logic is decidable, so is model checking of it, But in dense-time domain, the problem of model checking Timed Interval Temporal Logic is not clear. We prove that Satisfiability of Timed Interval Temporal Logic is un-decidable and we find a subset of Timed Interval Temporal Logic which can be decidable. So, it can be decidable to model checking the subset.

Key words: Timed interval temporal logic, Checking the satisfiability, Expressive power, Model checking
