Extended Object-oriented Petri Net Model for Mission Reliability Analysis of Complex Systems

This paper proposes an extended object-oriented Petri net(EOOPN) model for modeling and reliability analysis of complex system.EOOPN model has hierarchical structure and uses subnets to describe the subsystems in order to enhance the modeling modularity.Logical gate transitions are introduced to improve intuitiveness of transition fire conditions.In addition,broadcast place is used to reduce complexity.Finally,an example missile defense system is given to illustrate the application of the EOOPN model in reliability modeling of analysis of complex system.
