....blocks are IBC. There exists a theory of lattice structure of partition machines for hierarchical control ( Caines and Wei, 1995) Caines et al. 1997) and its extensions to hybrid case and supervisory control case can be found in (Caines and Wei, 37(4) 1998) P.E. Caines and Lemch, 1998) and (Hubbard and Caines, 1998). This theory asserts that all IBC partition machines of M constitute a lattice L and any chain from top to bottom in L provides a hierarchical control structure. Consider a base system M which may be represented by a directed graph. We observe the fact that if X i is an IBC block, then for any ....

.... and in computer science (see [4, 14] An aggregated modular approach to controller reduction also appeared in [27] An analysis of Petri Nets based on refinement and abstraction appeared in [26] with a corresponding analysis of policies that enforce liveness in [25] The present work builds on [7, 16, 17]. We give definitions for the partitions and high level dynamics for the hierarchical supervisory control automaton. Our primary interest is the problem of ensuring (non blocking) accessibility of the designated states and we show this problem may be decomposed and solved in a hierarchical fashion ....
