Modular Supervisory Control of Discrete-Event Systems with Abstraction and Incremental Hierarchical Construction

This paper addresses the problem of state explosion by outlining a procedure for incrementally building modular supervisors that are nonconflicting by construction. Abstractions are employed to make the procedure more computationally feasible. Proof is given showing the set of modular supervisors generated in this manner meet given specifications without blocking. Furthermore, an example is provided that demonstrates the reduction in complexity that this approach provides
