| Abstract(in English) | In this paper, we study a property of opacity in the language-based framework of discrete event systems. The problem of synthesizing a supervisor that enforces opacity in a maximally permissive way is addressed. A maximally permissive opacity-enforcing supervisor is realized by an automaton that generates the supremal closed controllable and opaque sublanguage of the generated language of the system. Under some assumption on observable and uncontrollable events, we present a formula for computing the supremal sublanguage for discrete event systems with observation masks. Whenever the languages under consideration are regular, the supremal sublanguage is effectively computed using the presented formula. |
