在前一篇论文中,我们定义了一个新的语义的时间自动机,几乎ASAP语义,这是参数化的Δ,以科普控制器的反应延迟。我们证明了这个语义是可实现的,只要存在一个严格的正值的参数Δ,该策略是正确的。在本文中,我们将可实现性问题定义为这样一个Δ的存在性问题。我们表明,这个问题是密切相关的时间自动机的鲁棒性定义在[Pur98]的概念,并证明可实现性问题是可判定的。
In a former paper, we defined a new semantics for timed automata, the Almost ASAP semantics, which is parameterized by Δ to cope with the reaction delay of the controller. We showed that this semantics is implementable provided there exists a strictly positive value for the parameter Δ for which the strategy is correct. In this paper, we define the implementability problem to be the question of existence of such a Δ. We show that this question is closely related to a notion of robustness for timed automata defined in [Pur98] and prove that the implementability problem is decidable.
