Maintenance managers have to make many tough decisions when it comes to keeping their business running efficiently. One of the big questions they face is whether to rely on prescriptive or predictive maintenance techniques. While the two methods share some similarities, there are also some key distinctions. In this blog post, we’ll take a closer look at those differences and help you decide which approach is right for your business.

1.      What is prescriptive maintenance?

Prescriptive maintenance is a term often used in the world of industrial and manufacturing maintenance. It is a type of maintenance based on specific parameters or criteria that must be met for equipment to operate safely and at its best performance levels. In other words, prescriptive maintenance takes into account the current condition of machinery and components, as well as their historical use, to determine what service or repairs are required to keep them running smoothly.

2.      What is predictive maintenance?

Predictive maintenance is a field of maintenance management that utilizes data analysis and modeling to anticipate failures or problems with equipment before they occur. This allows for preventive measures to be taken, thus avoiding downtime and preserving the life of the equipment. Predictive maintenance programs can be implemented in both large and small organizations and often rely on a combination of historical data, sensor readings, and machine learning algorithms. By considering all of these factors, predictive maintenance can provide businesses with an up-to-date view of their current health status and help them plan for future needs.

3.      The benefits of prescriptive maintenance over predictive maintenance

While predictive maintenance relies on historical data to make future repair predictions, prescriptive maintenance takes into account past performance data and the current condition of the equipment. It sets specific instructions for what repairs or replacements should be made. This can result in more efficient and effective maintenance activities.

4.      The benefits of predictive maintenance over prescriptive maintenance

Predictive maintenance takes a different approach. Instead of predicting failures, predictive maintenance indicates when parts will wear out or degrade. This information is used to schedule regular replacements or repairs before they cause problems.

5.      When to use prescriptive or predictive maintenance

Predictive maintenance implies monitoring the equipment’s condition and giving recommendations on how and when maintenance should be conducted. This means humans need to implement this type of maintenance. If one thus has a small or medium-sized facility or maintenance plant, this type of maintenance is sufficient.

On the other hand, Prescriptive maintenance aims to learn machines to make decisions about maintenance steps. Little human intervention is necessary, and maintenance is done through machine learning (ML) and artificial intelligence (AI). When you have a large facility and struggle to keep a tab of what is broken, in the process of failing, or what is functioning, this is the proper maintenance strategy for you.

In conclusion, prescriptive maintenance is a more proactive approach to maintaining equipment than predictive maintenance. Predictive maintenance is better at predicting when an issue might occur, while prescriptive maintenance takes it one step further by prescribing specific actions that need to be taken to prevent the problem from happening in the first place. Both approaches have their benefits, and choosing between them often depends on the specifics of each situation.
