Abstract:

Considering the large-scale, multi-level, separated and evolving characteristics of equipment system-of-systems (SoS), the modeling and analysis method is developed to solve the difficulty of prediction and allocation for equipment SoS reliability. This method, including the Department of Defense Architecture Framework (DoDAF) and process methods, is based on timing Petri net. After detailed analyzing the architecture and service process modeling procedure, the reliability calculation model of equipment SoS is built. A brief example of aviation support SoS in an airport is given to illustrate the process-based procedure of SoS reliability modeling and analyzing. The process execution time and reliability simulation results of equipment SoS are obtained through the Executable Specification Tool（ExSpect）simulation software.
