What is Maintenance and Reliability

You may have heard this old saying, “If it ain’t broke, don’t fix it!”. Many of us have believed that as long as something works, there’s no need to change it. But every time, you can’t get the same sort of picture. Things can go wrong when unnoticed.

That’s where maintenance and reliability make their share. They’re not just about fixing things after they break. They’re about being smart, and taking care of stuff before it causes trouble. It’s like you’re giving your car a routine checkup so that you can enjoy your ride peacefully.

Understanding Maintenance and Reliability

We’ll clear most of the myths and confusion about maintenance and reliability through our course and how it can make your life easier.

What is Maintenance?

Maintenance is like giving a shot of insulin to a diabetic patient regularly so he doesn’t collapse anytime. You build checkpoints for any specific equipment or system and inspect it after a certain period, to prevent any malfunction. It helps you keep the strategy in its best position. 

Now, there are different types of maintenance you have experienced at least once in your lifetime. Let’s take a look at these:

Reactive Maintenance (RM)

It’s a sunny day. You’re in the office and suddenly your wife calls, giving you unpleasant news. The kitchen sink has been clogged. What will you do? Calling a plumber would be an instant option that will come to your mind. But let’s take a moment to think about it. If you’re a certified maintenance and reliability professional, you would fix this immediate problem and identify the root cause and preventive measures. This can stop future complications. That’s what we call Reactive maintenance. It’s like a superhero that saves your day from an unusual problem. 

Our reliability management course equips you with the skills to effectively address equipment failures and maintenance issues, empowering you to tackle unexpected challenges and prevent future complications.

Preventive Maintenance (PM)

Got idea of what it means by the word prevention? You take your car to the mechanic for oil changes and tune-ups even when it’s running fine. But if you have done our reliability engineering fundamentals training course, you can also identify the signs of wear and tear that could go unnoticed by a mechanic. That’s how preventive maintenance works. It’s all about staying proactive and taking care of equipment before it becomes a bigger issue. You’re giving the assets a little makeup to keep them running smoothly and avoid headaches later on.

Predictive Maintenance (PdM)

You can consider this type of maintenance like a magic ball for assets. You can predict when something might go wrong so you can fix it before it breaks down. Consider a network of delivery trucks for a respective company. You can implement predictive maintenance instead of waiting for trucks to have any problems during the journey. Having an expert maintenance and reliability professional will help you give suggestions, such as the installation of advanced sensors on each truck. If any abnormality is detected, such as a slight increase in engine temperature or low tire pressure, the system sends an alert to the maintenance team. This will help you form a set of preventive measures and also repair the original problem. It helps you to have a heads-up about potential issues with the stuff.

Breakdown Maintenance

You are a lazy person who only reacts to potential emergencies when they happen. That’s breakdown maintenance. Let’s say you’ve been hired by a busy factory, and suddenly, one of the most important machines stops working. The production has been stopped and now you’re worrying about what to do to fix it as soon as possible. Now, in this picture, consider, you remember all the lessons you learnt our maintenance & reliability certification course taught you. It’s like your personal coach, helping every system to remain in its top position. Other maintenance activities aren’t possible due to the breakdown of assets.

Reliability Management: Making Every Minute Count

You’re planning to visit a restaurant but don’t know if it’s worth your money. You might ask your friends about their experiences there to see if the restaurant consistently serves good food or service. That’s exploring reliability – you’re gathering information to see if you can trust that restaurant to give you a good meal.

It’s about understanding how likely something can work properly to ensure optimal performance and minimize downtime, you rely on historical data and maintenance records to gauge the reliability of each asset. This process involves assessing past performance to determine the likelihood of future success, much like evaluating the reputation of a restaurant before dining there.

Key Reliability Metrics

We’ll discuss prime important key metrics with you that are used in reliability. It will help you understand how reliability works in daily life.

Mean Time Between Failures

This index helps you to calculate on average a light bulb in your room lasts before it burns out. If you have a bulb with a Mean time between failures is 100 hours, then on average after every 100 hours, the bulb will fuse. We can use a mathematical formula to express it as

MTBF = Total operating time / Number of failures

Mean Time to Repair

Let’s say your refrigerator is not working. How much time an electrician will take to repair it will be your mean time to repair. You can use this formula to calculate MTTR as:

MTTR= Total downtime / Number of failures

Overall Equipment Effectiveness

You can take any example around you to describe this term while considering performance, quality, and availability. For example, your wifi connection can best describe it. Performance can be its speed, loading response, and user numbers. You can explain availability as giving the best speed even in harsh weather or in load shedding. Quality can be its MBS. It has high overall equipment effectiveness if all these requirements are best fulfilled by your Wifi connection. The formula is as:

OEE = Availability×Performance×Quality

Failure Rate:

How many times weather forecasts have failed to give you reliable examples during the past month? If it’s giving more updates on weather that are not happening, it means its failure rate is high. On the other hand, giving an update that it will rain tomorrow and it rains that day, will decrease the failure rate.

The formula for failure rate depends on the specific context and units used.

These examples illustrate how reliability metrics apply to everyday situations, helping you understand the performance and dependability of various systems.

Why Maintenance and Reliability Matter

In our hectic routine, we rely on countless assets, systems, and processes to keep things running smoothly. From the machines in factories that make our favorite snacks to the airplanes that take us on adventures, reliability is far and wide. And maintenance? Well, it’s the secret seasoning that keeps everything running along.
