Vulnerability Assessment Based on Fuzzy Bayesian Network

In the process of aircraft vulnerability assessment, the model is always simplified because of inaccurate data, which leads to imprecise vulnerability assessment. In this paper, fuzzy mathematics and Bayesian network are used to evaluate aircraft vulnerability, which makes the vulnerability analysis more accurate. This paper introduces the basic knowledge of fuzzy theory and Bayesian network, as well as the aircraft vulnerability assessment process based on fuzzy Bayesian network, and establishes a vulnerability assessment model based on a certain type of aircraft. Finally, an example proves the rationality of this method.
