2. Importance of assessing the criticality of equipment: different methods of assessing criticality
2.1 Defining equipment criticality
The adoption of predictive maintenance requires technical, methodological, organizational and human investment, with significant financial costs. It is therefore essential to select only those items of equipment whose failures are considered critical. Today, for equipment to be considered critical and justify predictive maintenance, it must have serious consequences in the event of failure, notably on production, the safety of goods and people, the environment, costs, regulatory compliance and organizational resilience.
Furthermore, the concepts of industries 4.0 and 5.0 have introduced new requirements in terms of sustainability and resilience, which it is crucial to take into account in this approach. Historically, the first...
