Abstract

The preemptive reconfiguration strategy is one of the important fault-tolerant strategies in avionics systems. In the strategy, the functional role conversion of redundant units and the determination of system state under resource priority bring challenges to the reliability assessment. To solve this problem, this paper establishes a hierarchical DFT model for the avionics system. In the DFT model, preemptive reconfiguration (PR) gate and degraded AND gate are designed to accurately depict the preemptive reconfiguration behavior and system states. In addition, the article proposes a Monte Carlo simulation algorithm based on cut sequence set model, which can deal with structural function changing during the reconfiguration process.
