Background, Context: Optimizing the process availability cannot be reached by reducing the global cost of the process life cycle when maintenance is not predictive. On the one hand, corrective maintenance is commonly used even if it has many limitations due to production stops and downtime, when a failure occurs; on the other hand, preventive maintenance is used to avoid any production stops an...
