Distinguish between types of industrial maintenance to manage your operations with a master's hand
Do you know all the different types of maintenance, what specific needs they meet, and which software solutions are best suited to boosting productivity?
As a prudent, proactive company, you need to deploy a maintenance strategy to ensure that your equipment is well looked after, that it's running at peak performance, and that your business continues to run smoothly. Your productivity depends on it, as does customer satisfaction!
Can you tell the difference between preventive maintenance, corrective maintenance and predictive maintenance? What are they used for? Here's a quick overview of the different types of maintenance and the software used to manage them.
1. Preventive maintenance
Preventive maintenance is : performed at predetermined intervals or according to prescribed criteria, and designed to reduce the probability of failure or degradation of the operation of an asset or the degradation of a service rendered" (AFNOR).to reduce the probability of failure or deterioration in the operation of an asset or the degradation of a service rendered" (AFNOR).
In a proactive approach, it takes several criteria into account to anticipate malfunctions in an asset or service:
- regulations affecting certain equipment and infrastructures, to comply with standards (in the pharmaceutical or aeronautical industries, for example),
- user feedback and machine reports,
- manufacturers' recommendations, to be taken into account with a view to enforcing warranty or quality assurance in the event of a breakdown.
In the latter case, we sometimes speak of pre-determined maintenance, which does not depend on the actual state of the machines, but on statistical programs supplied by the manufacturers (based on mean time to failure [MTTF], for example).
There are two sub-categories of preventive maintenance: systematic maintenance and condition-based maintenance.
2. Systematic maintenance
This is established according to a schedule or periodicity of use (every month, every 500 products manufactured, every 10,000 kilometers, etc.). Rather simple to manage thanks to its fixed frequency, it facilitates organization and considerably reduces the risk of serious damage or deterioration.
It is particularly useful when :
- restarting takes a long time
- the shutdown has been going on for some time,
- the failure causes significant costs,
- the problem threatens safety.
3. Conditional maintenance
This is based on the condition, i.e. the actual state of the equipment, via continuous or regular monitoring and direct connection.
Degradation of the asset is measured by means of self-diagnosis, sensor information, wear measurement, etc. It's highly cost-effective, as it doesn't require extensive inventory management, purchasing or unnecessary intervention.
4. Corrective maintenance
As opposed to preventive maintenance, which anticipates malfunctions, corrective maintenance takes place after the failure or breakdown of an asset or production line.
The aim is to repair, restore or replace a part or piece of equipment, or to correct a bug or poor computer programming.
Two sub-categories of corrective maintenance exist: palliative maintenance and curative maintenance.
5. Palliative maintenance
Palliative maintenance is used to temporarily repair a fault, rather like a band-aid, so that the equipment can continue to function relatively normally.
It is a great help in avoiding the need to stop the activity in progress. However, it is important not to let the temporary situation drag on, and to ensure that safety is maintained until a more permanent solution is found.
6. Curative maintenance
Curative maintenance is aimed at permanently repairing the sources of breakdowns (as opposed to palliative maintenance). All or part of the equipment will be replaced, depending on whether the breakdown is major or minor, total or partial.
Some people use the term "curative maintenance" as a synonym for "corrective maintenance", but it is only a sub-category of the latter.
7. Predictive maintenance
Predictive maintenance is considered by some to be part of preventive and condition-based maintenance, since it tends to monitor machines and the crossing of thresholds (wear, etc.) to avoid breakdowns.
But it's a separate category. According to standard NF EN 13 306 X 60-319, predictive maintenance (the term "predictive" is an Anglicism) is carried out according to forecasts extrapolated from the analysis and evaluation of machine parameters.analysis and evaluation of significant parameters of asset degradation, in particular thanks to sensors installed on machines and connected (IoT, Internet of Things).

Ermeo
Ermeo is a SaaS solution that facilitates and optimizes maintenance operations. During rounds and interventions, agents enter their observations and non-conformities directly into the application, using intuitive, intelligent and comprehensive forms. Team leaders can then access the data in real time on the Ermeo web platform, and plan any corrective actions required. As a result, you can improve agent efficiency by up to 20%, and reduce re-interventions by 70%.
