Abstract: A computationally efficient solution for a class of forbidden state problems is developed. The authors consider discrete event systems (DESs) which can be modeled as cyclic controlled marked graphs. The distributed representation of the DES state in terms of the CMG marking permits an efficient specification of the forbidden states. It is shown that the graphical representation of the state transition logic in a CMG can be used to synthesize state feedback logic. An application of the results is illustrated in the field of FMS.
