Kimon P. Valavanis & Padmini Srinivasan Pages in Dissertation, 157; Words in Abstract 300 The objective of this research is to develop a model-based approach to the modeling, analysis and design of multilevel systems. Petri Nets are used as the basic modeling tool because of their versatility in the modeling and analysis of dynamic system behavior. Moreover, Petri Nets have a strong mathematical background and Petri Net analysis techniques are well established. Hierarchical Time-Extended Petri Nets (H-EPNs) are proposed as a hybrid modeling and analysis tool for the derivation of the coordination level model [205, 231] of hierarchically decomposable systems, viewe..
