Failure and Reliability Predictions by Infinite Impulse Response Locally Recurrent Neural Networks
Abstract
In this paper, Infinite Impulse Response Locally Recurrent Neural Networks (IIR-LRNNs) are employed for forecasting failures and predicting the reliability of engineered components and systems. To theauthors' knowledge, it is the first time that such dynamic modelling technique is used in reliabilityprediction tasks. The method is compared to the radial basis function (RBF), the traditional multilayerperceptron (MLP) model (i.e., the traditional Artificial Neural Network model) and the Box-Jenkinsautoregressive-integrated-moving average (ARIMA). The comparison, made on case studiesconcerning engine systems, shows the superiority of the IIR-LRNN with respect to both the RBF andthe ARIMA models, whereas a similar performance is obtained by the MLP.
