Real-Time Equipment Health State Prediction with LSTM Networks and Bayesian Inference

Conference paper
Part of the Lecture Notes in Business Information Processing book series (LNBIP, volume 423)


Due to the emergence of sensing technology, a large number of sensors is used to monitor the health state of manufacturing equipment, thus enhancing the capabilities of predicting abnormal behaviours in (near) real-time. However, existing algorithms in predictive maintenance suffer from several limitations related to their scalability, efficiency, and reliability preventing their wide application to various industries. This paper proposes an approach for real-time prediction of the equipment health state using time-domain features extraction, Long Short-Term Memory (LSTM) Neural Networks, and Bayesian Online Changepoint Detection (BOCD). The proposed approach is applied to a real-life case in the steel industry and extensive experiments are performed. The paper also discusses the results and the conclusions drawn from the proposed approach.
