    Samenvatting

    When the Ramadge-Wonham supervisory control paradigm is applied to practical problems, it is desirable to require a closed-loop system be finitely coreachable in the sense that a marker state can be reached within a finite number of transitions regardless of the current state. Furthermore, considering that actions in a real system usually carry costs, it is desirable to synthesize a supervisor that incurs only a minimum cost. Pursuing finite coreachability with a minimum cost is the main motivation for developing a theory about optimal supervisory control of weighted discrete-event systems in the literature. In this paper we follow the same line of optimal supervisory control but with a new focus on partial observation, which is common in practical applications. We first define three finitely-weighted supervisory control problems, namely (1) to decide the existence of a finitely-weighted controllable and normal sublanguage; (2) to compute a finitely-weighted controllable and normal sublanguage, when the answer to Problem (1) is affirmative; (3) to compute the supremal minimum-weighted controllable and normal sublanguage, when the answer to Problem (1) is affirmative. Then we provide concrete algorithms to solve them.
