| Abstract: | The dynamic characteristics of resource backup and reconstruction are considered, and a generalized
stochastic Petri net is used to model the reliability of a typical avionics system architecture with resource backup
mechanism. Through model simulation in TimeNet platform based on the availability index of functional modules, the
reliability of the system task is evaluated. The obtained transient simulation results effectively predict the time domain
characteristics of the system availability. The steady-state analysis results are highly verified by numerical verification.
The modeling method provides a reference for assessment of the reliability of the avionics system. |
