Research of security analysis based on subjective Bayesian Networks

Considering the uncertainties of evidence, regulation and reasoning in the security analysis of complex equipments, this paper made use of the theory of subjective Bayes methods, introduced the odds function, made an subsection interpolateing transaction of the conditional probability function, represented the data in a uniform framework with the Bayesian Networks and gained a rule of how to express the uncertain information in an accurate way. The result of the example showed the arithmetic is more accurate.
