Whether a corrective, preventive, or predictive maintenance plan is most appropriate for a given product or asset must be determined by maintenance works for any type of asset. Selecting the proper maintenance activity necessitates understanding of each strategy and how it could affect your resources and work schedule because each approach to maintenance has advantages and disadvantages of its own. Equipment breakdowns can be expensive, thus the most logical course of action may seem to be to implement a predictive maintenance policy that anticipates failures and allows for the implementation of corrective action in advance. However, some non-essential equipment might wear out without actually being an issue and can often be quickly and affordably fixed. A maintenance crew may be inclined to acknowledge a corrective maintenance technique under such circumstances. Run to breakdown may also be used when remedial action is impractical. For instance, some spacecraft and satellites may be built with no maintenance assumptions and allowed to operate until they fail (and then abandoned). Preventive maintenance is a third sort of technique that is frequently employed by business. This strategy aims to stop a failure before it happens, similar to predictive maintenance, but there is a small variation between the two, which we go into more depth about below. Management software, such as CMMS Software (Computerized Maintenance Management System), which may help monitor resources in actual time, schedule maintenance, and track work orders, can help organize a condition-based maintenance strategy. Predictive maintenance Because it uses a more thorough method to determine when maintenance is required, predictive maintenance varies slightly from preventive maintenance. Predictive maintenance employs analytics and ongoing data monitoring to identify whether mechanical failure is probable to appear rather than using a specified time or usage pattern to decide when repair is necessary. This kind of monitoring enables maintenance to be carried out as needed to address a particular issue and stop an asset from malfunctioning. Predictive maintenance is frequently more cost-effective than preventative maintenance since it only alerts the user when a malfunction is about to occur. Benefits of Predictive maintenance Lower spending This method eliminates the excessive maintenance costs related to preventative maintenance because maintenance is only carried out when necessary. Since faults are fixed before total equipment failure occurs, maintenance chores are frequently less expensive than with reactive maintenance. By being able to schedule repairs and downtime for equipment, this not only cuts down on the cost of the time spent performing maintenance, but it can also cut down on other costs, including overtime. Higher reliable asset performance If your equipment is properly maintained, it will be more dependable and perform better. By ensuring that your machinery is operating properly, a predictive maintenance solution can lengthen the life of your equipment. Countless other benefits of preventative maintenance, including as improved safety, cost control, energy savings, and reduced disturbance to work schedules, are included in this increased reliability. Reduced downtime This maintenance method can significantly cut down on downtime or outages brought on by failing equipment. Smaller fixes and tune-ups help stop bigger issues from arising, keeping output and customer satisfaction high. Routine Maintenance You can schedule maintenance because you are in command of your equipment's condition. Instead of getting an expensive reactive approach, you can make sure the necessary specialists but also components are on-site when there is time to make repairs. You can also minimize interruptions to workflow to increase productivity and profits. Product Quality Improvement Machines that are not properly maintained can malfunction and produce items that are defective. By keeping an eye on your machinery, you can make sure that every component is working properly and continuously producing high-quality goods. Predictive maintenance have some drawbacks as follows Increasing Initial Costs You will pay more up front for a preventive maintenance program than you would if you let anything wear out on its own. Regular maintenance costs money in terms of time, wages, and parts. You must determine whether this is higher than the possible cost of allowing something to fail naturally, though. Requires knowledge of data interpretation To evaluate the data from your predictive maintenance technology, you'll need qualified personnel. It's crucial to perform your vital data analysis appropriately in order to accurately identify when a problem is about to occur or maintenance is necessary. The equipment and the quality monitoring both require an understanding on the part of your technicians. This can necessitate hiring new employees or undergoing staff training, but these expenses might end up being cost-effective in the medium to long term. Despite the inherent benefits of preventive and predictive methods, corrective maintenance may in some circumstances be the best option. Corrective maintenance is frequently the recommended course of action when the expenditure of part failure and replacement is less than the expenses of preventive or predictive maintenance. Therefore, in the situation of a light bulb, for instance, remedial action is unquestionably the best choice because the expense and time required to change the bulb are not expected to have a significant impact on finances or work schedules. This alters, though, as the component is required for multiple functions, like in the case of a engine’ ships or a blade for a wind turbine. Corrective maintenance can indeed be especially harmful when it doesn't actually been selected as a course of action; allowing something to fail inadvertently can be expensive in terms of time, money, and safety. When the cost of waiting for something to break is too high, a part is too important, difficult to replace, or could seriously affect health and safety of employees or work schedules, preventive monitoring is used. Although this method is not required for all things, it enables the maintenance of that are more significant. This will lessen the possibility of unplanned outages, increase the asset's lifespan and performance, and make it easier to identify any unanticipated causes of failure. Predictive maintenance is becoming the strategy of choice for asset owners. It not only provides many of the advantages of preventive maintenance, but it also performs it in a more effective and economical way. A condition-based control method can be used to notify you only when measures are needed, minimize unnecessary maintenance fees while preserving your equipment in excellent condition. Although there are expenses associated with setup, after these have been budgeted for, they can be used. Sensors can be employed to remotely control a variety of operating factors, including oil quality, vibration, and cracking. As technology evolves, monitoring and data collecting performance improves at a lower cost, this kind of maintenance is becoming increasingly accessible. Which monitoring strategy to use will depend on the organization and the application. While taking a corrective, proactive approach with some objects is completely appropriate and even preferred, many will need this kind of routine maintenance or monitoring. It holds true for every single thing, from little machine parts to huge buildings or structures. The frequency of maintenance examination is determined by preventive maintenance, which might be based on prior inspection data. Maintenance needs for certain assets or objects may also be specified by equipment manufacturers, laws, and even standards. These maintenance plans may need to be modified over time to improve their cost- and maintenance-effectiveness. Motor circuit analysis, laser-shaft alignment, infrared analysis, oil analysis, Vibration analysis and ultrasonic analysis are the six key tools available for predictive maintenance.In order to provide an even more successful method, predictive maintenance is utilizing new technology, such as the artificial intelligence. Among the most popular leading Predictive Maintenance Software include Presenso, GE Predix, and Siemens MindSphere. I personally don’t believe that installing sensors for a lightbulb in your desk lamp is an effective form of maintenance strategy, but of course, everything still relies on the exact timing of the nature of the environment or piece of equipment.

Predictive Maintenance Predictive maintenance is a type of maintenance strategy that uses data and analytics to predict when a piece of equipment is likely to fail. The goal of predictive maintenance is to identify potential failures before they occur, so that maintenance can be performed proactively to minimize downtime and reduce the risk of unexpected equipment failures. Predictive maintenance is different from corrective maintenance in that corrective maintenance is performed after a problem has occurred, while predictive maintenance is performed before the problem occurs. Preventive maintenance, on the other hand, is performed at regularly scheduled intervals regardless of whether a problem has occurred or not. Corrective Maintenance Preventive Maintenance Predictive Maintenance Done after the failure or incident – Reactive Done prior to avoid failure or incident - proactive Done to forecast potential issues so that they can be avoided - proactive Does not involve any planning, cost effective in short term Lot more complex planning. Scheduled basis system run time. Expensive to begin with Scheduled basis need using real time condition of system. Relative more complex to implement. Can be very expensive to begin with depending on sensors or tools reqd. Process is simple as its done only when needed. At other times the maintenance team can focus on other activities Labour intensive and maintenance team always has some assets to work on. Maintenance carried out whether reqd. or not Performed only as needed so more efficient Very expensive on long term as the failure or incident would cause damage to system. Asset lifecycle is reduced Expensive but avoids damage to system. Asset life cycle is improved Over long term the maintenance cost will be minimum. More efficient in utilizing asset life before replacing Has risk of injury for employees Better for safety of employees Better for safety of employees Downtime of assets and therefore impact on productivity is high Downtime of assets is low Downtime of assets is minimum Since it only focuses on issue and not the cause, chances of repeat failure are high Chances of failure is low Chances of failure is very low Can be suitable when cost of part is significantly cheaper than cost of predictive or preventive maintenance Suitable when cost of failure or breakdown or repair is very high Benefit of preventive maintenance but more efficient and cost effective There are several tools used for predictive maintenance, including: · Vibration analysis: This involves measuring the vibration of machinery to identify issues such as misalignment, imbalance, or bearing wear. · Thermography: This involves using infrared cameras to detect changes in temperature that can indicate potential problems with electrical equipment, mechanical equipment, or other components. · Oil analysis: This involves analyzing the oil used in machinery to identify contaminants and wear metals that can indicate potential problems with the machinery. · Machine learning algorithms: This involves using data from various sensors and sources to build predictive models that can help predict equipment failures. · Condition monitoring software: This software collects and analyzes data from various sensors and sources to provide real-time information on the health of equipment, which can be used to identify potential problems before they occur. · Ultrasonic testing: This involves using high-frequency sound waves to identify potential problems with equipment such as cracks or corrosion. · Electrical signature analysis: This involves analyzing the electrical signals produced by machinery to identify potential problems with the equipment's electrical components. · Wear debris analysis: This involves analyzing particles generated by the wear of machinery to identify potential problems with the equipment's components. These are some of the most commonly used tools for predictive maintenance, but there are many other tools and techniques that can be used depending on the specific needs of the equipment and the organization.
