Mission reliability simulation of aggregated equipment combat units for the mobile mission based on Petri net

The mission reliability of equipment combat units is an important factor for its operational effectiveness, and also one of the important basic to measure other performance of equipment combat units. There are kinds of mission reliability parameter, and in this paper the parameter of mean time between failures is adopted. Based on the analyses to the levels of the aggregated equipment combat units, this paper analyzes the signification for aggregated equipment combat units´ mean time between failure, describes the simulation method and simulation flow for the mobile aerial defense mission of aggregated equipment combat units, and then constructs the simulation model with Petri-net and ExSpect. Finally, the paper probes into an example to prove that the simulation model has relatively practicability.
