Supervisory control theory deals with problems related to the existence and the synthesis of supervisors. The role of a supervisor in a system is to control and restrict the behavior of this system in order to realize a specific behavior. When there are multiple supervisors, such systems are in fact multi-agent systems. The results of supervisory control theory are usually expressed in terms of operations like intersection and inclusion between formal languages. We reformulate them in terms of model checking problems in an epistemic temporal logic. Our reformulations are very close to natural language expressions and highlight their under-lying intuitions. From an applied perspective, they pave the way for applying model checking techniques developed for epistemic temporal logics to the problems of supervisory control theory.
