An Improved Fault Propagation Analysis Method Based on Small-world Algorithm for Large Scale Electronic Systems
Abstract: Single source
multipath fault propagation analysis has contributed much on system fault modeling,
fault location, and fault diagnosis. Studies have shown that the electronic
system has small world network features. In this study, a new model of small
world was established to observe the rapidlyfault propagation of the electronic
systems. In order to meet the higher requirements of testability and reliability
for complex electronic systems, an improved fault propagation analysis method
based on smallworld algorithm was proposed. First, inspired by the idea of
small-world networks, a small world algorithm was proposed to greatly improve
the speed of getting the fault path compared with other evolutionary algorithm.
In addition, calculating entropy was firstly introduced to distinguish the
importance of differentnodes in systems. Finally, the proposed method was
applied to a radar transmitter system for faultpropagation analysis. The result
shows that the performance is improved a lot by introducing the small world
characteristic and simplified entropy. Simulation results demonstrate the
computation method. Also, fault propagation could be applied to large-scale
systems, which is meaningful for test points selection and fault diagnosis.
