Abstract:

To comprehensively evaluate ADS-B system operating reliability,we put forward a method which employs T-S fuzzy neural network.In this model,5 reliability indices (mean time to first failure,mean time between failures,mean time to repair,mean availability and repair time rate) are taken as input vectors,and a nonlinear mapping relationship of the reliability comprehensive evaluation is established by T-S fuzzy system.The neural network is adaptively trained to adjust fuzzy rules and membership functions.The comprehensive evaluation model of ADS-B system operating reliability is established base on aforementioned method.The results of simulation and application show that the method is feasible and effective with high computational stability,accuracy and good generalization;and that the evaluation results are objective,accurate and reliable,which is of value in decision-making for improving operation reliability of ADS-B system.
