Abstract:
Avionics networks work in a real-time manner where the intended functions should be performed before time deadline. To assess the reliability of an avionic network comprehensively, the metric delay as well as the commoncause failures are taken into consideration and a taskbased model with delay constraints is built. Moreover, an efficient ordered binary decision diagram (OBDD) based approach, named time-constraint edge expansion, is proposed which incorporates delay constraints into the edge expansion diagram to construct OBDD and analyzes network reliability with commoncause failures on the basis of the original OBDD. A sample network is shown to illustrate the evaluation procedure using the proposed approach. The experiment results verify the correctness and efficiency of the approach in reliability analysis for avionics networks.
