3. Systematic maintenance

Based on our knowledge of the operating behavior of equipment and its components, this maintenance method involves carrying out monitoring operations (inspection, replacement of parts) according to a schedule expressed in units of use. This is often the first preventive maintenance strategy to be implemented in a production sector, as it appears to be the simplest to implement. However, it comes up against two major obstacles which, if not properly identified and satisfactorily resolved, can cause the project to fail:

• precise determination of the intervention schedule: this determination is based essentially on experimental reliability data for the components and/or sub-assemblies concerned. It requires sufficient knowledge of the asset's behavior in operation. Intervening too early quickly leads to prohibitive costs, which negate the benefits...
