摘  要:
A new way for parameter estimation of reliability model based on adaline neural network was developed by means of mathematical analysis and theory of artificial neural network with Matlab. The result obtained from the simulation of the Exp model and Weibull distribution is better than those from other methods,including the regress analysis and the reliability paper for the common reliability model in engine reliability. The model parameters and function of reliability for the first fault time of a tractor were gained by this means. The parameters estimation of the reliability model could be quickly obtained if the life data of the known probability distribution was input to the model of the artificial neural network.
