Reliability Assessment of Avionic Device Based on Fuzzy Theory and GO Methodology

This paper studies the reliability assessment issue of avionic device. A method based on fuzzy theory and GO methodology is proposed to the issue, the state cumulative probability is adopted to simplify the computation, GO model is built with the consideration of shared signals, and the fuzzy GO operation is deduced based on triangle fuzzy number. Finally, an example about a monitor module of some avionic device is given as an illustration. Test shows that, besides the simple and effective characteristic of GO methodology, this method is more flexible in dealing with the problems that the accurate probability of some event cannot be obtained, and it provides useful reference for the relative fields.
