Abstract: The control of complex cybernetic systems involves decision making networks which operate on the ``Command, status and message layers'' of concurrent decision making activity. Decision making ``nodes'' function as multitasking operators on all three layers. Aspects of real-time concurrency in hierarchical command decomposition are analyzed in this paper, using mainly concepts and tools of Petri-net theory.
Keywords: complex cybernetic system; decision making network; message layer.
