This book focus on key component required for building predictive maintenance model. The
current trend of Maintenance 4.0 leans towards the preventive mechanism enabled by predictive
approach and condition-based smart maintenance. The intelligent decision support earlier
detection of spare part failure fatigue detection is the main slices of intelligent and
predictive maintenance system (PMS) leading towards Maintenance 4.0 This book presents
prominent use cases of mechanical engineering using PMS along with the benefits. Basic
understanding of data preparation is required for development of any AI application in view of
this the types of the data and data preparation processes and tools are also presented in
this book.
