The Three Types of MaintenanceCorrective Maintenance. Corrective maintenance is what to do when something breaks; it's better known as repairs. Preventive maintenance tries to spread costs by planning activities on a regular basis. Simplify preventive maintenance, schedule work orders and track inventory That's one of the answers.
Another is that new technologies make new strategies possible. When new technology gives us a new ability, we can leverage it in a new strategy. For condition-based maintenance and predictive maintenance, for example, sensors mounted on your assets and equipment capture a constant stream of data that you can use to help determine when to schedule upcoming inspections and maintenance tasks. Here, you use a program of inspections and tasks to find and fix small problems before they have a chance to become major problems.
Preventive maintenance is basically the idea behind the old saying that “An ounce of prevention is worth more than a pound of cure. One way to understand the benefits of preventive maintenance is to analyze all the problems that are avoided. Default maintenance is simply following the manufacturer's recommendations for maintenance, including when to perform inspections and maintenance. Basically, it's the same as condition-based maintenance, except that the data is analyzed to make accurate predictions about future failures.
You now have the same condition-based maintenance costs, plus the additional cost of even more sophisticated software that requires even more specialized training for your staff. For assets that don't fit either of these descriptions, it probably makes more sense to use preventive maintenance. As with many other strategies, you don't have to make a difficult decision between strictly one or the other. When an asset is newer, you can use default maintenance.
Later, when you have created a maintenance and repair history, you can begin to adjust the schedule to best suit your specific situation. Choosing the right maintenance strategy starts with understanding your options, benefits, and drawbacks. Execution to failure tends to get a bad reputation, but for a specific asset class and equipment, it's the best option. Use when things are difficult or impossible to maintain, cheap to carry in inventory, easy to replace, or not essential to your operations.
Preventive maintenance helps you find problems ahead of time when scheduling inspections and tasks. It also saves you money and frustration because you can plan everything in advance. For default maintenance, everything is basically the same as with preventive maintenance, except that it follows a schedule set by the manufacturer, not by your department. Condition-based and predictive by relying on sensors and special software to collect and analyze data from sensors installed directly on or near your assets.
For conditions, the software looks for readings outside the preset parameters. For predictive purposes, the software analyzes the data to predict future failures long before they begin to develop. In the end, there is no one and only perfect strategy for all time. You need to choose the combination that works best for your assets, adjust your focus as your assets age and your department collects data.
Preventive maintenance aims to detect and fix problems before they occur. It is usually carried out in the form of regular inspections, which usually occur several times a year. The main benefit of preventive maintenance is that it can eliminate unplanned downtime, since the ideal is to detect problems before they occur. Condition-based maintenance is sometimes considered a more advanced alternative to preventive maintenance.
Instead of being inspected according to a schedule, machines and systems are carefully observed for changes that may indicate imminent failure. This type of maintenance is performed by technicians in charge of industrial maintenance before any failure or malfunction occurs. Refers to spare parts, components and machinery and equipment to reduce the risk of failure. The digitalization of industrial enterprises has provided many IT and technology solutions that allow technicians to effectively perform, monitor, track and plan preventive maintenance.
The emergence of data processing and analysis solutions, as well as artificial intelligence, has allowed manufacturers to plan predictive maintenance based on the prediction of failures and malfunctions. This type of industrial maintenance allows companies to anticipate problems by planning necessary interventions and maintenance operations based on forecasts. In this way, you can limit expenses caused by unexpected breakdowns, equipment downtime and production interruptions. This type of preventive maintenance is distinguished by its frequency.
Technicians perform this regularly and systematically at well-defined time intervals beforehand. This allows components and spare parts to be replaced regularly, improving machine productivity. Therefore, systematic preventive maintenance is based on the regular inspection of the various equipment, which allows maintenance technicians to gather the necessary information about the various components of the production line and effectively prevent breakdowns and repair costs. Conditional preventive maintenance consists of monitoring the key parameters and indicators of the operation of the property and implementing the necessary corrective actions to anticipate any failure or malfunction.
There are many emerging IT tools available to automate this type of industrial maintenance. Thus, technicians and maintenance workers can simplify and facilitate their work by opting for the digitalization of industrial maintenance processes. Predictive maintenance is generally considered to be the most advanced and intensive type of maintenance. This is because this type of maintenance does not go through the scheduling process of full maintenance planning & because it is very urgent and is simply planned on the fly.
If you're interested in learning more about how to better manage failure modes, don't forget to check out my article Reliability-Focused Maintenance: 9 Principles of Modern Maintenance. Predictive maintenance requires a level of technology that standard preventive maintenance does not require, and may also require employees who can accurately interpret condition monitoring data. In fact, world-class organizations ensure that less than 2% of their total maintenance is emergency maintenance. Corrective maintenance can be planned or unplanned, depending on whether or not a maintenance plan has been created.
To be successful in the field of building maintenance, it is useful to understand the different types of maintenance methods that exist and how and when they are used. I appreciate your great efforts and informative articles and I am interested in reliability (especially the RCM) and maintenance scheduling, so I ask you about planning preventive maintenance activities. Regardless of the decision you make, you need to provide maintenance teams with maintenance management software to ensure proper supervision of interventions, as well as smooth communication between technicians and other professionals. If you have resource constraints, you need to ensure that you have high productivity during execution (read my articles on maintenance planning, scheduling &) and that you don't waste your scarce resources on preventive maintenance tasks that add no value (read my article on the principles of modernity maintenance).
I don't think you can, fundamentally, predictive maintenance is the same as condition-based maintenance, since it aims to prevent or, at least, mitigate the effect of a failure before the failure occurs. Reactive maintenance is commonly used to respond to a tenant's request to repair items in their units and preventive maintenance is used to regularly inspect and replace filters on essential assets, such as an HVAC machine. A next-generation CMMS such as Mobility Work, a solution that offers a performance analysis tool capable of collecting all the data entered by the maintenance teams themselves, aims to progressively help plants evolve towards predictive maintenance. Unlike other styles, default maintenance is performed using rules and suggestions created by the original manufacturer, rather than the maintenance team.
