Types of maintenance (definitions, benefits, cost, examples), preventive maintenance, predictive maintenance, planned maintenance, condition-based maintenance. Preventive maintenance refers to resolving problems before they appear. This means that such maintenance avoids the problem. Inspecting equipment at regular intervals to check the condition of the machine and take the necessary measures is the motto of preventive maintenance.
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.
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. Predictive maintenance (PdM) aims to predict faults before they occur so that maintenance can be done at the right time.
PdM uses machine sensor data and intelligent technology to alert maintenance staff when equipment is at risk of failure. For example, a sensor can use vibration analysis to alert maintenance staff that equipment is at risk of failure, at which point it will be disconnected, inspected, and repaired accordingly.

Corrective maintenance is any maintenance task that resolves a problem with an equipment and returns it to its operational state.
As the name suggests, this type of maintenance refers to predicting the probability of equipment failure and scheduling maintenance to avoid failures. As with all types of maintenance, relying solely on preventive maintenance has potential drawbacks. Normally, following the instructions in the equipment manufacturer's maintenance plan, a fixed interval is scheduled and maintenance work is carried out to restore the efficiency and performance of the equipment. 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.
There are many other types of maintenance that work well for all types of organizations, from small stores drowning in paperwork orders to data-based business operations, for which predictive maintenance is a reality. In the condition-based maintenance (CBM) strategy, the actual condition of the asset is monitored and additional maintenance requirements are decided. In short, reactive maintenance usually involves more downtime and higher maintenance costs when not used strategically. .
