Abstract

According to the characteristics of vulnerability assessment of aircraft guarantee system on board, a new system vulnerability evaluation method is proposed based on improved fuzzy reasoning algorithm of fuzzy Petri net(FPN). In the improved algorithm, the learning algorithm on unknown weight coefficients is introduced, making the evaluation system get rid of experts or experiences. The results comparison between the presented method and damage tree analysis method demonstrates exhaustiveness and rationality of this model. The model would be applied to the complex ship system assessment.
