Different types of maintenance exist because maintenance teams within different organizations have different budgets, equipment needs, and service level agreements with customers and internal departments like production.
Because so many types of maintenance exist, it’s hard to know which one is best for your organization. To narrow down your options, identify your maintenance budget and the acceptable level of unplanned downtime for each asset. Then, with this information, look through the different types of maintenance and select viable candidates.
If you’re having trouble understanding the pros and cons of different maintenance types, follow the links to the relevant comparison articles below. These articles compare two types of maintenance side by side. You’ll learn about how each maintenance type works, how much it costs to implement, how much money it saves, and how the pros and cons of one weigh against the other.
Both preventive maintenance and predictive maintenance are designed to increase the reliability of assets and reduce the amount of reactivity to failures. The main difference between the two is that preventive maintenance is scheduled at regular intervals while predictive maintenance is scheduled as needed based on asset conditions.
Preventive maintenance and breakdown maintenance both seek to maintain and repair equipment but they have very different ways of doing this. In some ways, breakdown maintenance is the opposite of preventive maintenance because maintenance work doesn’t occur until a downtime event happens as opposed to avoiding downtime events by performing maintenance before they happen.
Both preventive maintenance (PM) and reliability centered maintenance (RCM) are designed to increase asset reliability and lifespan by creating a system of scheduled work. Both systems can be expensive in different ways. Preventive maintenance systems can be expensive due to their large scheduling needs while reliability centered maintenance systems often have a larger upfront cost.
Predictive and condition-based maintenance are both maintenance types that occur before breakdowns happen. The primary difference between them is the way in which maintenance is measured. Predictive maintenance relies on precise formulas in addition to sensor measurements. Condition-based maintenance relies only on real-time sensor measurements.
Both corrective maintenance and emergency maintenance happen in response to a fault or issue with equipment. The main difference between the two is the scale of that problem. Corrective maintenance is used for regular maintenance activities while emergency maintenance is used when an event causes safety issues or losses in production.
While planned maintenance and scheduled maintenance sound like the same thing, some essential differences exist between them. Simply put, planned maintenance details how and what work will be completed; scheduled maintenance determines who will complete the work and when it will be completed.
Run to failure (RTF) maintenance and breakdown maintenance both aim to fix problems that occur when equipment breaks down, although the intent of each maintenance plan looks slightly different. In RTF maintenance, the maintenance team expects certain parts to break down and plans for that to occur. In breakdown maintenance, there is no planned strategy. The maintenance team simply responds and hopes they have everything they need to make the repair.
