Multilayered petri-nets for distributed decision making*

Decision making networks, employed for the control of complex cybernetic systems,6,7,8,9,10 operate on the "Command, Status, and Message Layers" of concurrent decision making activity. Decision making "nodes" function as multitasking operators on all three layers, by executing command decomposition, status reporting, and message exchanging tasks for the concurrent implementation of various control policies. Aspects of real-time concurrency in hierarchical command decomposition over the command layer of the dm-net are, more particularly, analyzed in this paper, using concepts and tools of Petri-net theory. 2, 3, 4, 5,11,12,14 * This work was partially supported by National Science Foundation Grant Number 1ST 84-08063.
