Regards, Hello, please I want to know the various maintenance aids. But, if you are only dealing with 50 liters of oil the time and effort it takes to sample the oil and analyse it probably means its not worth going condition-based and you simply change that oil out based on a fixed time or fixed number of running hours. On the flip side, preventive maintenance is not able to detect more immediate maintenance issues and may result in unplanned downtime. These maintenance management strategies can be used together, or independently. Would you allocate all the costs to preventive maintenance or would you only allocate the cost for the initial inspection to preventive/proactive maintenance and allocate the repair/bring back to original state to corrective/reactive maintenance? Need a quick comparison of these four strategies? 1. When opting for corrective maintenance as a strategy it is essential to ensure that the failure modes under consideration do not have the potential to become Emergency Maintenance. All the preventative tasks have been grouped together and cannot be distinguished to see where the problem is. Your email address will not be published. Second is about Surveillance / monitoring tasks A CMMS or facilities management software can help eliminate the need for stacks of paper and confusing spreadsheets. Reliability Centered Maintenance (RCM) and Predictive Maintenance takes PM to the next level. The only time you should be conducting unplanned maintenance is when you have a high-priority work request that comes in and is so urgent that you break into the Frozen Weekly Schedule to complete the work without going through the normal planning & scheduling process. They do not represent a mathematical partition of all the maintenance tasks. By doing so, you can work to minimize the risk of failure and ensure greater accessibility to your equipment. Reactive Maintenance Emergency Maintenance Corrective Maintenance Maintenance Applications Facility Maintenance Property Maintenance Why worry when you can Coast? You can adjust your preferences inCookie Settings. No problem Moses, all you need to do is click on one of the Download the Types of Maintenance Toolkit buttons, enter your email and the PDF will be in your inbox in a matter of minutes. Thanks for your article. Instead I always like to point out that non-age related failure modes are typically > 70% of the failure modes we need to manage. Predictive maintenance is designed to schedule corrective maintenance actions before a failure occurs. There are many differently types about services strategies. Apart from being the outcome of a deliberate Run to Failure strategy Corrective Maintenance is also the result of unplanned failures which were not avoided through preventive maintenance. When you implement a Risk-Based Maintenance process effectively you should have reduced the total risk of failure across your plant in the most economical way. This is why the time-based maintenance is weak. This is highly inefficient and something you should avoid at all cost. Just a cent from me. Hi Jacob, thank you for your comment. As such it is a type of preventive maintenance. However, reactive maintenance is not a practical solution in the long term for repairable assets. If we are not careful we will train all maintenance engineers of the future in these vintage theories. 4 types of maintenance strategy, which one to choose? I believe the solution to this is Predictive Maintenance in the form of simple wireless remote monitoring IoT network sensors that monitor your assets on a 24/7 basis that alerts you in real time to any abnormalities it detects preventing costly damages and maximising up-time. But, in many peoples minds, breakdown maintenance is urgent maintenance, maintenance that needs to be done right now i.e. Types of Maintenance: Main Strategies and Alternatives. Precision maintenance is the next step in the evolution of predictive maintenance, maintaining a laser focus on equipment reliability and uptime. Hi Fethi, that depends on the type of maintenance that is actually contained within the procedure. And once detected youll have to repair the failure you found. Congratulation Eng. A vey nice article topic-per-topic. thank you so much for detailed information concerning the different types of maintenances, Eng. And when to use each one? How hard are you willing to work to save $100? 1. Hi Debo, thanks for your comment. Here, we will examine the different types of maintenance strategies in greater depth. All Preventive Maintenance should be Planned Maintenance as it has been identified upfront and there is no reason why it would not go through the normal maintenance planning & scheduling process. Reliability-centered maintenance (RCM) addresses the fact that failure is not always linear. Ditch paperwork, spreadsheets, and whiteboards with Fiixs free CMMS. Consider the analogy of car maintenance, and the example of the car that doesnt receive regularly mandated service, only to suffer a catastrophic, multi-system failure that suddenly demands extensive and expensive repairs. It will be worth your time. The rise of the industrial internet of things (IIoT) is making it possible for organizations to use intelligent maintenance software to collect data and integrate with connected devices to get smarter about manufacturing. While it's usually best to prevent issues altogether, this is not always possible. Hope this will help complement your nice work ! Each is built around the concept of planned maintenance, although they are all organized and scheduled differently, to suit different business operation purposes. The goal of precision maintenance is to maximize time between failures or maintenance events and minimize downtime (planned or unplanned), resulting in an increase in productivity and efficiency while lowering overall maintenance costs. Dont forget to read my article on the principles of modern maintenance if you are interested in RCM. If a critical failure occurs, it can cause unnecessary delays in production that can cost more in lost production time than it would have cost to implement a more proactive maintenance strategy in the first place. Even if nothing comes of these alerts, using the data produced by the sensors can help you make better decisions about how to manage your equipment going forward. We support a comprehensive range of products for electrical distribution networks: Submit your inquiry and we will contact you. Whenever a person or entity submits a service request, the maintenance team that receives it must create a formal paper and/or digital document that includes all the details of maintenance tasks and outlines a process for completing the tasks. From an asset perspective, more extensive data collection and analysis made possible with todays AI and IoT solutions hasenabled manufacturers to get valuable data that has improved the reliability of their operations and products. Increase your maintenance workforce by 35% without hiring anyone. Solved 7. There are four (4) key types of maintenance - Chegg IBM Maximo Predict puts machine learning and data analytics to work for you, increasing asset reliability as it looks for patterns in asset data and usage. The ATS Advanced Technology Services, Inc. logo is a registered service mark of Advanced Technology Services, Inc. AC Current Sensors and Current Monitoring in Industrial Maintenance, ATS Modern Slavery and Human Trafficking Statement, Corrective maintenance (or reactive maintenance). This seems to be just a small detail, but it is enough to create a confusion in terms of classification and logic for those who would think that preventive and corrective would represent 2 distinct categories of the maintenance tasks listed in a manual (Unfortunately many manuals do this mistake or this simplification). the failure modes are hidden. That's why, predicting asset failure has been top of mind for businesses since the 1980s. The good point you mentioned it. etc. One famous approach is risk-based management decision. The subject is very interesting. Whereas preventive maintenance is maintenance that has been identified to prevent or mitigate a failure mode. by providing analytics on all potential failure modes and building a custom plan to address each parts stability. and wish you success. If any of these conditions exceeds thresholds for normal operation, alerts are immediately sent to maintenance personnel to address the issues promptly before they lead to failure. The good news is IBM can help. Developing a robust maintenance strategy requires weighing the benefits and costs it brings to the table. However, be careful with other random corrosion mechanisms like stress corrosion cracking which is not age-related and really needs to be designed out or managed through methods than time based PM. Wrench time is basically the time your technicians are doing actual maintenance tasks so that excludes travel time, waiting time, time spent looking for parts and materials, time spent waiting for permits, time spent on breaks or meetings etc. Erik 4 Types of Maintenance Maintenance activities are typically broken down into 4 types of maintenance: corrective maintenance (CM), preventive maintenance (PM), condition-based maintenance (CbM), and predictive maintenance (PdM). Drive smarter decisions and engaging experiences with a hyper-connected real estate platform. However, most failure modes do give some sort of warning that they are in the process of occurring or are about to occur. The 5 Types of Maintenance. Some people get very excited about these definitions and can spend a lot of time on for example disagreeing with what is and what isnt preventive maintenance. And lastly, implementing a predictive maintenance strategy requires a cultural change to accommodate the shift from predetermined to more flexible daily operations, which can be challenging. It is most commonly carried out in the form of regular inspections, usually occurring multiple times per year. Hi Erik, most of key maintenance KPIs are lagging and most of them rotate on down time; which leading maintenance measures can I use and be able to control the outcomes of the maintenance process in a manufacturing industry? A.Sghair. Hi Moses, there are many KPIs or performance metrics that you can use to manage and improve maintenance. prepared), Every time we use the preventive maintenance of drilling material and equipement to be really used and avoiid the corrosion . Whether for better or for worse, many businesses only bother dealing with equipment when theres already a problem. Save my name, email, and website in this browser for the next time I comment. If we can get them to stop breaking it, we wont have to fix it as often. A look at the tools that empower your maintenance team, Manage maintenance from anywhere, at any time, Track, control, and optimize asset performance, Simplify the way you create, complete, and record work, Connect your CMMS and share data across any system, Collect, analyze, and act on maintenance data, Make sure you have the right parts at the right time, AI for maintenance. At least, the way I see it: There are 9 maintenance types split between Preventive Maintenance and Corrective Maintenance. Consider a single piece of industrial equipment. This type of maintenance helps analyze and determine different options and potential outcomes, in order to mitigate any risk to the operation. As a maintenance strategy, corrective maintenance is inefficient and costly in terms of resources, spare parts and potential downtime, since maintenance only occurs at or near a failure state. Over the past decade, Industrial Internet of Things (IIoT) technology has transformed maintenance principles, enabling organizations to install smart devices that monitor the manufacturing floor. . I refer to this as Emergency Maintenance. The ultimate purpose of this strategy is to check for potential issues to prolong the life of your assets. When the quality of production is impacted due to unreliable equipment and costs skyrocket because of unplanned servicing, its probably time to consider a preventive maintenance program. They help us make our website usable, enabling you to move around the site and use its features. a vibration reading, corrosion under insulation, ) found a possible error (upcoming bearing damage, a corrosion mechanism that cab lead to failure, ), does the repair or bring back in original state still fall under preventive maintenance or better to say proactive maintenance? I had faced many times discussions with Maintenance heads on which is their maintenance strategy, and it is very frustrating that we have to start from basics and jump into a maintenance strategy or philosophy to respond to the business or equipment requirements. Preventive and predictive maintenance are proactive maintenance strategies that use connectivity and data to help engineers and planners to fix things before they break. Join over 14,000 maintenance professionals who get monthly CMMS tips, industry news, and updates. When choosing a maintenance strategy, it is important to understand you budget, goals, and risk tolerance. Lube oil change out on a turbine with thousands of liters of oil is often best done on condition to ensure you get the maximum life out of the oil. Hi ghassan, I wrote this based on my own industry experience, but there are actually a couple of international standards that cover this and where most of the industry terminology comes from. And then you have planned (i.e. Viktor, Hi Viktor, yes the notion that time-based maintenance is the best solutions remains wide-spread. Thanks. every 150 cycles, every 10,000hrs, or like your car: service every 10,000km. If you are testing e.g. Train and empower them to drive improvement in your business. Similarly, performing too many PMs can open the door for post-PM breakdowns. IBM Maximo improves scheduling, vendor management and both workflow and financial reporting all without paper. If you are resource-constrained then you need to ensure you have high productivity during execution (read my articles on maintenance planning & scheduling) and that you are not wasting your scarce resources on preventive maintenance tasks that dont add any value (read my article on the principles of modern maintenance). And because the consequence is low we can simply accept that general lighting is run to failure. For the next lines, please allow me to consider that the plant maintenance is part of safety matter due to the true goal is to preserve an asset from failure and decline (of course at the end to ensure business continuity). Use a simple, proven framework of just 4 Essential Elements to create a Reliable Plant: 40%-60% of PMs add little value. Thank you for a lot of detailed information concerning the different types of maintenances, thanks for the information concerning the difference of maintanance. Achieve higher reliability with less maintenance. I agree that in many companies penny-pinching is a problem when it comes to maintenance, but I strongly believe that in those same companies maintenance teams do themselves a big disservice by executing a lot of non-value-adding maintenance tasks. | Privacy Policy | Terms of Use | Cookie Settings. I have confused about preventive maintenance and which better: renewal or replacement of complex assets. Maintenance types: Strategies & alternatives Infraspeak Blog The principles applied here will also apply to medical equipment. I am honest in confessing that till I read the entire article i did not realize that the difference between various types of planned and unplanned maintenance. Algorithms are also used to build models that predict when future potential problems may arise, which mitigates the risk of the asset breaking down further down the line. Hi Narender, I think we are actually very aligned in that your planned maintenance is the equivalent of my preventive maintenance and your unplanned maintenance is what I would call corrective maintenance. I fully agree with what you state here. Preventive maintenance is regular and routine, whereas predictive maintenance focuses on providing the right information about specific assets at the right time. Keeping these cookies enables us to display advertisements that are more relevant to you and your interests. The interval can be time-based (days, weeks, or months) or usage-based (operating hours, cycles, or km). Hi Erik, firstly thank you for this simplified theoretical maintenance strategy.
