A Formula for Computing the Supremal Controllable and Opaque Sublanguage in Discrete Event Systems

Abstract (in Japanese) (See Japanese page) 
(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.
This motivates the study on computability of the supremal sublanguage.
We present a formula for computing the supremal sublanguage
under some assumption on uncontrollable events.
Whenever the languages under consideration are regular,
the supremal sublanguage is effectively computed using the presented formula.
