Abstract : The growth of prognostics study in manufacturing and engineering sectors has been rapidly increasing in recent years. With proper usage of IoT, big data and predictive analytics, all industries aim to improvise productivity, product lifetime and durability, ultimately improving customer satisfaction. Predicting Remaining Useful Lifetime (RUL) for deteriorating machines is helpful in avoiding unnecessary stoppages in production or usage of a product. This work focuses on understanding the scope and significance of prediction of RUL and use of machine learning models to achieve results of good precision. A comparative study on pros and cons of regression versus classification models is presented. In addition, the interpretation of the dataset used, influence of the features to the RUL estimation, significance of the presence of outliers in such run-to-failure data is examined.
