Preventive and curative maintenance
 
            Optimized maintenance management is necessary to manage and reduce breakdowns in order to limit operational
            downtime and obtain optimal productivity. There are two types of maintenance: preventive maintenance and corrective maintenance.
        
        
            
            Preventive maintenance is the periodically scheduled overhaul of equipment, with if necessary the 
            replacement of worn parts, to avoid a breakdown. These maintenance operations limit additional 
            costs linked to equipment breakdown, operating losses and are often necessary when unscheduled 
            operating shutdowns are not acceptable. Preventive maintenance has a cost, but a priori lower 
            than that of corrective maintenance.
            
Corrective maintenance is the troubleshooting of equipment, a system or a machine when it is out of order. We speak respectively of curative or palliative maintenance if the repair is definitive or temporary.
