Colored observers, a generalization of the observer property, together with local control consistency, allow to derive sufficient conditions for synthesizing modular and hierarchical control that are both strongly nonblocking (SNB) and maximally permissive. A polynomial procedure to verify if a projection fulfills the above properties is proposed and in the case they fail for a given projection an algorithm is proposed to find an extension of the set of events to be projected, in order to fulfill the sufficient conditions for SNB and maximally permissive hierarchical control.eninfo:eu-repo/semantics/closedAccessDiscrete Event SystemsHierarchical ControlMaximal Permissiveness.MultitaskingConference Object10.3182/20100830-3-de-4013.000182-s2.0-80052003674
