What Is the Difference Between Periodic and Predictive Maintenance?

Do you know the condition of your pieces of equipment and assets? Are they getting proper maintenance on time or not? Maintenance is crucial for business, but the question is which type of maintenance suits your business! In this blog, we will explore what predictive and periodic maintenance are and compare them as well.

Periodic and predictive maintenance are two important maintenance types. Both have many similarities, but they are different from each other. So, let us begin with periodic maintenance!

What Is Periodic Maintenance?

Periodic maintenance is a scheduled maintenance type. In clear terms, it is time-based maintenance. After a certain defined period, periodic maintenance is performed. This specific period is defined by maintenance managers after analyzing the data. It can be daily, weekly, or monthly. Periodic maintenance results in extending equipment life, increased reliability, and decreasing downtime.

Periodic maintenance can be used on those assets which are very valuable to daily operations so that production and productivity do not stop. MTBF (Mean Time Before Failure) and MTTR (Mean Time to Repair) play an important role in periodic maintenance and its implementation.

What Are the Advantages of Periodic Maintenance?

The advantages of periodic maintenance are discussed below:

1. Increased Productivity  

When assets are given maintenance on time, it increases reliability and decreases the chance of asset failure. Thus, increased productivity.

2. Decreasing Downtime  

Periodic maintenance increases uptime and decreases downtime, especially unplanned downtime which can be dangerous for business.

3. Scheduled Maintenance  

When assets are maintained regularly, the time needed to perform maintenance is minimized, plus maintenance costs are also minimized.

What Is Predictive Maintenance?

Predictive maintenance is very similar to preventive maintenance. In this maintenance, assets are utilized until they are working efficiently.

It is a method that utilizes data, tools, and strategies to distinguish and identify irregularities in your daily activities and potential deformities in pieces of equipment so you can fix them before they fail.

Predictive maintenance permits the maintenance frequency to be as low as possible to prevent unplanned reactive maintenance, without causing costs associated with excessive preventive maintenance.

According to Markets and Markets, “The global predictive maintenance market size is expected to grow from USD 4.0 billion in 2020 to USD 12.3 billion by 2025, at a Compound Annual Growth Rate (CAGR) of 25.2% during the forecast period.”

What Are the Advantages of Predictive Maintenance?

The advantages of predictive maintenance are discussed below:

1. Real-Time Monitoring  

Equipment is monitored in real-time with the help of asset tracking technology, providing real-time information to assist in decision-making based on accurate data.

2. Minimized Maintenance Expenses  

When maintenance is done right before failure, it saves a lot of expenses because the maintenance frequency is minimized.

3. Increased Return on Investment (ROI)  

When machine uptime increases and downtime decreases, machines work longer hours, resulting in an increased return on investment.

Periodic Maintenance Vs Predictive Maintenance

Periodic maintenance and predictive maintenance have their own merits and demerits. Here is a comparison:

1. Predictive maintenance is less frequent whereas periodic maintenance is done more frequently.

2. Periodic maintenance is time-based (scheduled) maintenance activity whereas predictive maintenance activity depends on the condition of the asset.

3. The costing in periodic maintenance is very predictable but in predictive maintenance cost cannot be predicted.

4. Periodic maintenance is simpler but predictive maintenance is complex.

5. To perform periodic maintenance any technician can do but for predictive maintenance high skilled technician is required.

6. Periodic maintenance consumes more resources than predictive maintenance.

7. Predictive maintenance has no specific time to perform whereas periodic maintenance is done after a specific time interval.

8. Periodic maintenance is less risky whereas in predictive maintenance calculated risk is taken.

9. Predictive maintenance and Periodic maintenance have their own merits and demerits. Overall, periodic maintenance is good when you don't want to risk. On the other hand, if you can take the risk predictive maintenance can be very fruitful to your business by saving a lot of money.

What Are the Similarities Between Periodic Maintenance and Predictive Maintenance?

Similarities between periodic maintenance and predictive maintenance are as follows:

1. Both are used for scheduling maintenance.

2. They are proactive by nature.

3. Both help decrease unplanned downtime.

4. They save maintenance expenses.

Conclusion

Every maintenance type has its advantages, but you need to determine which type of maintenance works best for your business based on daily operations and business requirements.

However, maintenance types alone are not effective; you must utilize computerized maintenance management software (CMMS).

A CMMS provides several benefits that can help your business grow. For instance, you can view maintenance reports, track maintenance, and access maintenance history to help the maintenance team make informed decisions.

Frequently Asked Questions (FAQs)

How many types of maintenance are there?  

There are several types of maintenance, such as preventive maintenance, predictive maintenance, emergency maintenance, corrective maintenance, condition-based monitoring, etc.

Why is maintenance management important?  

Maintenance management is important because it is a critical part of well-functioning production. Maintenance keeps assets in good condition, makes them reliable, and prevents asset breakdown.

What are the asset tracking technologies?  

There are many types of asset tracking technologies such as Barcode, QR Code, RFID (Radio-frequency identification). These technologies are used for tracking assets and can provide information about each asset. Furthermore, you can also know if an asset is in a running state or in a halt state!
