eMaintenance: Essential Electronic Tools for Efficiency is a practical guide for anyone interested in running a plant as a smart asset. The book explores how to improve and enhance efficiency of operations, maintenance staff, infrastructure managers, and system integrators using a real time computerized system from data to decision.

In recent years we have seen the exciting possibilities of eMaintenance become a recognized source of productivity improvement in industry. The seamless linking of systems and equipment to control centres for real time reconfiguring is improving efficiency, reliability, and sustainability in a variety of settings. Methods of overcoming the challenges of data collection and processing are explained before the introduction of tools for data driven condition monitoring and decision making.

Key Features

  • Includes links to eMaintenance applications and MATLAB code which can be downloaded and used
  • Provides an introduction to collecting and processing data from machinery
  • Explains how to use sensor-based tools to increase efficiency of diagnosis, prognosis, and decision-making in maintenance
  • Describes methods for overcoming the challenges of data collection and processing


Reliability and Maintenance Engineers with an interest in Industry 4.0. Researchers in the field of Industry 4.0, manufacturing, and machinery
