Distributed simulation algorithms of generalized differential Petri nets

The generalized differential Petri nets (GDPN) proposed previously (2002) to model hybrid dynamic system, make the modeling of continuous time dynamic process and discrete event dynamic process in a uniform framework, but the evolution rule of differential transition increases the time complexity greatly. So a distributed simulation scheme is used to simulate the generalized differential Petri nets. First, the definition of GDPN is introduced and the structure constraints are analyzed. Then the place and transition nodes (discrete or differential) in the model are decomposed into several sub-nodes. The distributed simulation scheme suitable to GDPN is discussed. The simulation method of special structure such as the conflict structure and deadlock and its avoidance, is also considered.
