Resilience and Sustainability plants improvement through Maintenance 4.0: IoT, Digital Twin and CPS framework and implementation roadmap

The Fouth Industrial Revolution is the new innovative wave that touches any sector, bringing great innovation. As the benefits that Industry 4.0 can create are very high, it is mandatory to deeply investigate it and elaborate full applications. Digital technologies require to be faced with a correct pace, beginning with a small pilot, able to generate quick and valuable results. A domain in which Industry 4.0 can bring a great and positive effect is Maintenance, with predictive and prescriptive maintenance. In this research, it is analyzed how Internet of Things (IoT), Digital Twins (DT) and Cyber Physical System (CPS) can enhance maintenance and how they can be integrated to create the Maintenance 4.0 framework, with a clear focus on Resilience and environmental Sustainability, applied with a 6 steps roadmap based on the "starting small" authors' approach and initial assumption.
