Four general types of maintenance philosophies can be identified, namely, corrective, preventive, risk-based and condition-based maintenance. Another is that new technologies enable new strategies. When new technology gives us new capacity, we can take advantage of it in a new strategy. For condition-based maintenance and predictive maintenance, for example, the sensors installed 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 turn into big 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 consists of 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 faults. It now has the same maintenance costs depending on the conditions, plus the additional cost of even more sophisticated software that requires even more specialized training for its staff. For assets that don't fit any 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 choice between strictly one or the other.
When an asset is newer, you can use default maintenance. Later, when you've created a maintenance and repair history, you can start adjusting the schedule to better suit your specific situation. Choosing the right maintenance strategy starts with understanding your options, benefits and drawbacks. The tendency to fail usually has a bad reputation, but for a specific asset class and equipment, it is the best option.
Use it 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 detect problems early by scheduling inspections and tasks. It also saves you money and frustration, since you can plan everything in advance. For default maintenance, everything is basically the same as with preventive maintenance, except that you follow a schedule set by the manufacturer, not by your department.
State-based and predictive using sensors and special software to collect and analyze data from sensors installed directly on or near your assets. Depending on the conditions, the software searches for readings outside the preset parameters. For prediction, the software analyzes the data to predict future failures long before they begin to develop. In the end, there is no perfect strategy for all time.
You must choose the combination that best suits your assets, adjusting your approach as your assets age and your department collects data. There are 9 types of maintenance divided between preventive maintenance and corrective maintenance. This type of maintenance is carried out by the technicians in charge of industrial maintenance before any failure or malfunction occurs. Refers to spare parts, components and machinery and equipment in order to reduce the risk of breakdowns.
The digitalization of industrial companies has provided many IT and technological 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 faults and faults. This type of industrial maintenance allows companies to anticipate problems by planning the necessary maintenance interventions and operations based on predictions. Therefore, it makes it possible to limit expenses caused by unexpected breakdowns, equipment downtime and production interruptions.
This type of preventive maintenance is distinguished by its frequency. Technicians carry it out regularly and systematically, with time intervals well defined beforehand. This allows components and spare parts to be replaced regularly, improving machine productivity. Therefore, systematic preventive maintenance is based on a periodic inspection of the various equipment, which allows maintenance technicians to gather the necessary information about the different components of the production line and effectively prevent breakdowns and repair costs.
Conditional preventive maintenance consists of monitoring the parameters and key indicators of the operation of the property and implementing the corrective actions necessary to anticipate any faults or malfunctions. There are many emerging IT tools available to automate this type of industrial maintenance. In this way, technicians and maintenance workers can simplify and facilitate their work by opting for the digitalization of industrial maintenance processes. Reactive maintenance is a maintenance system that responds when machinery or systems fail.
I appreciate your hard work and informative articles, and I'm interested in reliability (especially the RCM) and maintenance scheduling, so I'm asking you about planning preventive maintenance activities. To understand what types of maintenance to implement, you must know what types you are currently using and what your maintenance objectives are. But, in the minds of many people, fault maintenance is urgent maintenance, maintenance that must be done right now i. Unfortunately, books rarely specify this distinction, leading to the mixing of oranges and apples under the same general term of “maintenance tasks”, which is not precise enough to correctly describe other maintenance concepts within preventive maintenance.
Another key difference is that preventive maintenance involves inspecting and maintaining assets regardless of whether the equipment needs maintenance (the maintenance program is based on a trigger). Non-routine maintenance includes maintenance that is performed reactively or only when necessary depending on the condition of an asset. When choosing corrective maintenance as a strategy, it is essential to ensure that the failure modes being considered do not have the potential to become emergency maintenance. Corrective maintenance may or may not be planned, depending on whether or not a maintenance plan has been created.
I don't think it's possible, fundamentally predictive maintenance is the same as condition-based maintenance, since it aims to prevent or at least mitigate the effect of a fault before the fault occurs. Planning refers to the process of scheduling %26 maintenance planning, so maintenance planning consists of preparing maintenance work so that it is ready for execution. Preventive maintenance consists of proactively initiating maintenance tasks and plans to prevent faults from occurring. An excellent example of predetermined maintenance is when machinery maintenance is scheduled at intervals of time according to the manufacturer's recommendations.
