What are 4 types of maintenance?

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.

Performing corrective maintenance means that when a problem is detected, the maintenance associated with the problem is carried out before the problem worsens. An example would be if a technician is performing a planned inspection and, in the meantime, detects a problem, the technician will perform corrective maintenance, so that the problem does not cause a fault or other type of failure. Condition-based maintenance is carried out based on minimum and maximum indicators. This means that a task will be activated in the maintenance system if, for example, the temperature exceeds the maximum value.

Therefore, the condition of the machine will indicate when maintenance should be carried out. When you work with predictive maintenance, it is based on the condition of the machines and equipment. This is done by monitoring the condition of the machines to predict when a possible breakdown will occur. Some maintenance systems can operate with predictive maintenance and calculate trend curves, based on the data that is written into the system.

This trend shows when it is necessary to carry out a job or task in the future. Preventive maintenance aims to detect and fix problems before they occur. It is usually carried out in the form of periodic inspections, which are usually carried out 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. Rather than inspecting them on a schedule, machines and systems are carefully observed for changes that could indicate an imminent failure. With condition-based maintenance, technicians observe the operation of the system and identify variables that could affect operation, such as temperature, vibration rate, power, the presence or absence of moisture, etc. Another strategy within condition-based maintenance is predictive maintenance.

Predictive maintenance refers to a specific type of condition-based maintenance in which systems are constantly observed through sensor devices. These devices are connected to system components and send constant, real-time data to the software. The software then interprets this data and warns maintenance technicians of the imminent danger. Predictive maintenance is generally considered to be the most advanced and intensive type of maintenance.

This is because there is a lot of data to interpret, and the sensor devices themselves must be maintained and verified regularly. Regardless of the type of maintenance strategies your equipment uses, different areas of a multi-family building should be regularly repaired to avoid costly repairs or extended downtime. Time-based maintenance is basically a type of maintenance that is performed at regular intervals while the equipment is still operating with the goal of preventing failures or reducing the likelihood of failure. Let's not do that, but I'll give you my vision of the different types of maintenance and, more importantly, when to use them.

The above table of maintenance types does not include autonomous maintenance or autonomous care (also referred to as front-line maintenance in other organizations). The most expensive type of maintenance is emergency maintenance, since it is the type of maintenance that is so urgent that everything is left to work and solve the problem. 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. The strategies and types of maintenance you would use for building maintenance will depend on the failure modes you want to manage and, of course, on legislative maintenance requirements.

An efficient and effective preventive maintenance program will have a combination of all these different types of maintenance. Predictive maintenance is actually a type of preventive maintenance, since both allow maintenance to be carried out before the failure occurs. Therefore, emergency maintenance is the only type of maintenance that we really want to avoid as much as possible. As with all types of maintenance, relying solely on preventive maintenance has potential drawbacks.

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. The 4 different types of software maintenance are: corrective software maintenance, adaptive software maintenance, perfective software maintenance, and preventive software maintenance. However, since I am often asked questions about different types of maintenance, I decided to give a quick overview of the types of maintenance. .
