how to improve mttr and mtbf

MTBF is used in the calculation of the Availability, which in turn is used to calculate overall equipment effectiveness (OEE): Example: Series system (most packing lines) Availability of an individual plant item (series system) Av 1 = 1 – MTTR/(MTBF + MTTR) (Where MTTR = mean time to repair = average time to return a failed component to service) Availability = MTTF / (MTTF + MTTR) where MTTF = Mean Time To Failure MTTR = Mean Time To Repair MTBF = Mean Time Between failure = MTTF + MTTR Examples: 1. Only by tracking these critical KPIs can an enterprise maximize uptime and keep disruptions to a minimum. The second concept is Mean Time To Repair (MTTR). %%EOF Whereas the MTTR, or Mean Time To Repair, is the time it takes to run a repair after the occurrence of the failure. 0 MTTR and MTBF are key indicators that are tracked to see the failure of your asset to evaluate how reliable they are so that this information is used to further update your PM Strategy. A primary goal for all system design is to reduce downtime—and the most effective way to do it is by designing reliable systems. If possible, automate the creation of tickets using an Application Performance Management (APM) system. Japanese concept of continuous improvement to increase the productivity of man, material and machine. This is the most common inquiry about a product’s life span, and is important in the decision-making process of the end user. Keep in mind that this isn’t a linear measure. MTBF, or Mean Time Between Failures, is a metric that concerns the average time elapsed between a failure and the next time it occurs.

By decreasing the amount of time that your systems are offline, you are increasing their overall availability and maximising your MTBF. Make good use of it will help you and your Maintenance team to improve the efficiency as well as performance of the processes. Mean Time Before Failure (MTBF), Mean Time To Repair(MTTR) and Reliability Calculators Mean time between failures, mean time to repair, failure rate and reliability equations are key tools for any manufacturing engineer. Mean time between failures (MTBF) is the arithmetic average time between failures. By tracking MTTR, organizations can see how well they are responding to unplanned maintenance events and identify areas for improvement. The Secret to Reducing MTTR and Increasing MTBF A primary goal for all system design is to reduce downtime—and the most efective way to do it is by designing reliable systems. Perhaps, a minor increase in the MTTR equates in a significant increase in MTBF. MTBF (Mean Time Between Failures) and MTTR (Mean Time to Repair) for NEPSI’s Metal-Enclosed Solutions You’ll need a large enough dataset, including outages over time, to develop an accurate picture of your MTTR. Paradoxically, it's also one of the most misunderstood metrics; many developers and operations teams lack a clear vision for how to define MTTR, how to use it, and how to improve it in a consistent and sustainable way. → Make an equipment breakdown history book and take a strong preventing action on it so this breakdown will not repeat in the future. MTBF is Mean Time Between Failures MTTR is Mean Time To Repair A = MTBF / (MTBF… However, if the process is lacking, PMs can have the opposite effect. The design expertise required to create systems to reduce MTTR and increase MTBF is not always widely available. Equipment is operational for 7884 hours (0.9 years) per year and requires 876 hours to repair, the availability is 90%. "Mean Time To Repair" is the average time that it takes to repair something after a failure. What that means is that a keypad with a 100,000 hour MTBF will have a one year survival reliability of 91.6% and a keypad with a 2.5M hour MTBF would have a reliability of 99.7% over the same period of time. endstream endobj 142 0 obj <>>>/MarkInfo<>/Metadata 9 0 R/Outlines 30 0 R/PageLayout/SinglePage/PageMode/FullScreen/Pages 139 0 R/StructTreeRoot 34 0 R/Type/Catalog/ViewerPreferences<>>> endobj 143 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/Shading<>/XObject<>>>/Rotate 0/StructParents 0/Tabs/S/TrimBox[0.0 0.0 612.0 792.0]/Type/Page>> endobj 144 0 obj <>stream อ ระยะเวลาเฉลี่ยตั้งแต่เสียหายจนใช้งานได้แต่ละครั้ง Being proactive can stop equipment issues before they even begin. A good example of the significance of MTBF can be found in the mining industry, where proper lubrication of field service equipment in rugged industrial environments can increase the MTBF of heavy haul trucks, crushers, and saw mills. MTTR is equal to the total down time divided by the number of failures. The first step in improving MTTR is to measure it, as discussed above. When we talk about MTTR, it’s easy to assume it’s a single metric with a single meaning. In manufacturing industries, we always worried about the break-down of machine or equipment failure, which can make a large loss and ultimately increase the downtime (Stop time) of the machine. MTTR, as it pertains to maintenance, is a good baseline for figuring out how to increase efficiency and limit unplanned downtime, therefore saving money on the bottom line. The time taken to repair a piece of equipment (the MTTR) might seem like a minor element in the calculation of MTTR, but the more you can reduce MTTR, the more your MTBF will improve. h��Xko۶�+��b�_^D�� �ݤ9��,N�mF0�6�Ԗ. 175 0 obj <>/Filter/FlateDecode/ID[<7B241366715745478AED9493ADA35791>]/Index[141 83]/Info 140 0 R/Length 148/Prev 204189/Root 142 0 R/Size 224/Type/XRef/W[1 3 1]>>stream It is easy to remove or add parameters to move the MTBF in a favorable direction, and customers should be wary of misunderstanding or misrepresentation. An increase in mean time between failures is an improvement, so you can see that the safety rate appears to be improving. h�b```�V�d!��1�0p�`X���0� Asset performance metrics like MTTR, MTBF, and MTTF are essential for any organization with equipment-reliant operations. You may not have a team of people in-house who thoroughly understand the complexities of this level of intelligent design, but experts can be found to assist you. endstream endobj startxref When used in conjunction with other maintenance strategies (such as failure code and root cause analysis) and other maintenance indicators (such as MTTR), it will help you avoid costly failures. For something that cannot be repaired, the correct term is "Mean Time To Failure" (MTTF). The higher the MTBF, the more reliable the asset. Mean Time to Repair (MTTR) is an important failure metric that measures the time it takes to troubleshoot and fix failed equipment or systems. The methodology of Why-Why analysis, MTTR and MTBF has been used here to implement Kaizen in an industry and compare the statistics of growth comparing it before and after the implementation of Kaizen. What is MTTR: Mean Time To Repair? Though the MTBF is 25X, the reliability increased by only 8 points. %PDF-1.7 %���� The Secret to Reducing MTTR and Increasing MTBF, 5225 Hellyer Ave. #250, San Jose, CA 95138. In other words, MTBF is a maintenance metric, represented in hours, showing how long a piece of equipment operates without interruption. MTBF is used to predict the probability of asset failure in a specific period or the frequency of occurrence of a certain type of failure. These lapses of time can be calculated by using a formula.
