What type of maintenance should you choose? An enlightening guide for your organisation

Explore maintenance strategies for better business performance. Learn about corrective, preventive, and predictive maintenance. Choose the right CMMS solution. Save costs and improve productivity.

Different types of maintenance exist, depending on the resources and requirements of the organization. Which should you choose for good performance?

Maintenance is not just about repairs. Behind these sometimes highly technical operations lies a host of economic, strategic and safety issues.

Every company, whatever its sector, will benefit from relying on quality maintenance. This will free up time for the human resources, improve understanding of the fleet, reduce costs and, ultimately, deliver sustainable improvements in production quality. In this respect, maintenance is a real cornerstone of the performance of any business.

And to manage this maintenance better, you need to understand what it’s made up of! Find out here about the types of maintenance and how each can support your business.

 

Corrective maintenance: the last resort?

Types of maintenance : Corrective maintenance Very commonly used by companies, corrective maintenance follows a breakdown and aims to restore the equipment to working order. The defective part(s) will be repaired or replaced. There are two relatively similar approaches to this process:

  • Palliative maintenance is an operation designed to restore a machine to working order on a temporary basis. In the strictest sense of the term, this maintenance enables production to be resumed quickly, but must be followed by a repair;
  • Curative maintenance, on the other hand, has a more lasting effect on the cause of the breakdown, by replacing all or part of the faulty component. It may follow palliative maintenance.

A distinction is also made between immediate corrective maintenance, which is carried out as soon as the fault is detected, and deferred corrective maintenance, which involves a later resolution for economic or logistical reasons.

Corrective maintenance has the major advantage of limiting short-term maintenance costs and simplifying management: in the best of cases, breakdowns can be limited and investment will therefore be minimal.

But this type of operation, which is more a reaction to an unforeseen event than planned work, generally has consequences on productivity.

Breakdowns, which are often unexpected, lead to production stoppages. This can even be prolonged if no technician is available to intervene at short notice. This can have serious economic consequences for the company, especially if the repair costs have not been anticipated. Corrective maintenance is therefore reserved for non-critical equipment.

Preventive maintenance: your best ally?

With preventive maintenance, the maintenance department carries out its actions at regular intervals or according to certain criteria in order to limit the occurrence of breakdowns. The technical instructions for the asset, the maintenance history and experience will be used to define the frequency of servicing, thereby guaranteeing the continuous operation of the machines over time.

There are generally three types of preventive maintenance:

types of maintenance : preventive maintenance

  • Systematic preventive maintenance: here we define a schedule of work based on when the asset entered operation or the last work carried out. It is used in particular on machines with regular cycles (heating systems, hydraulic presses, etc.)
  • Conditional preventive maintenance: this type of maintenance is not carried out at regular calendar intervals, but according to the state of a parameter specific to the equipment. We intervene, for example, if the temperature of a machine exceeds a critical threshold or if we observe an anomaly linked to speed, vibration, humidity, etc.
  • Predictive preventive maintenance: this is based on analysis and KPIs specific to an asset. Using the data, we will try to prevent failures and intervene only when necessary.

Preventive maintenance does involve additional costs, but corrective maintenance does not. But if its objectives are well-defined, it can extend the life and productivity of assets.

A good preventive maintenance plan and clear communication will be the keys to successful operations and cost savings in the medium and long term.

Predictive maintenance: a step towards the future?

Sometimes called predictive maintenance, analysis-based asset management is a real productivity booster. This is because the data collected on assets forms the basis for controlled operations, which will only be carried out when necessary. Maintenance then becomes more relevant and less costly than if it were carried out systematically.

Predictive maintenance is based on three conditions:

  • Anticipating the precise moments (time intervals and conditions) when the risk of breakdown is at its highest
  • Identifying the likelihood of this fault occurring
  • Predicting machine failures on the basis of warning signs or indicators

To anticipate possible breakdowns, we monitor a large number of KPIs: acoustic measurements, vibration analysis and thermography are all sources of information that can improve our understanding of a machine.

Types of maintenance : Predictive maintenance The increasingly sophisticated use of data is a real solution for the future for companies looking for maintenance 4.0. Although its implementation requires a certain amount of infrastructure and is a source of additional costs, the predictive system and its advice on maintenance make it possible to achieve virtually uninterrupted production. In fact, the scheme is set to become increasingly common in companies in the future, saving up to €600 billion by 2025.

 

How do you choose the right type of maintenance for your business?

The type of maintenance deployed in a company is often a strategic choice. The economic factor and the desire to anticipate costs, as well as the human and material capacity for repairs, are also taken into account. While corrective maintenance is still used in the majority of cases, many companies are trying to better anticipate their work.

To choose between one or other of the existing maintenance options, you can base yourself on:

  • The quantity of assets used
  • The likelihood of breakdowns or the current state of wear and tear
  • The criticality of these assets
  • The average maintenance cost of each machine
  • The staff available and their qualifications

Certain types of maintenance require the deployment of a specialist team or special site management. You can also combine several types of maintenance, although this involves more complex management work and rigorous monitoring, particularly in multi-site organisations.

Whatever the final choice, the organisation must be adapted to the effort you want to make. In some cases, it will be essential to use maintenance software to plan ahead.

Computerised maintenance management will then provide advanced analysis to reconcile the different types of maintenance in the most personalised way possible.

FAQs

What type of maintenance is the most economical in the long term?

Preventive maintenance is generally the most economical in the long term, as it prevents breakdowns and extends the life of the asset. For example, regular maintenance of industrial machinery can prevent costly and unexpected breakdowns.

When is palliative maintenance recommended?

Palliative maintenance is generally used when a full repair is not economically viable or possible. For example, an obsolete IT system may require palliative maintenance to maintain its functionality until it is replaced.

How do you choose between corrective and preventive maintenance?

The choice depends on the resources available, the nature of the equipment and the impact of a possible breakdown. For example, in a hospital, regular preventive maintenance of medical equipment is essential to avoid critical breakdowns.
