摘要

针对大型组合有限状态自动机系统,提出了一种模块化监督器组合综合的两步算法。第一次传递提供了一种有效的方法来确定监控问题是否有解决方案,而无需显式地构造所有组件的同步组合。如果存在解决方案,则第二遍产生最小限制解决方案的过近似值,如果非阻塞,则该解决方案是最小限制监督器的模块化表示。使用一种新型的不确定性过程等价,称为综合等价,可以在整个算法中采用广泛的抽象来缓解状态空间爆炸。

Yet another approach to compositional synthesis of discrete event systems
A two-pass algorithm for compositional synthesis of modular supervisors for large-scale systems of composed finite-state automata is proposed. The first pass provides an efficient method to determine whether a supervisory control problem has a solution, without explicitly constructing the synchronous composition of all components. If a solution exists, the second pass yields an over-approximation of the least restrictive solution which, if nonblocking, is a modular representation of the least restrictive supervisor. Using a new type of equivalence of nondeterministic processes, called synthesis equivalence, a wide range of abstractions can be employed to mitigate state-space explosion throughout the algorithm.
