No More Failure with MTBF

Mean time between failures (MTBF) is a proportion of how dependable a hardware product or part is. For most parts, the measure is commonly in thousands or even a huge number of hours between failures. The MTBF figure uses to be developed as the consequence of serious testing, in light of genuine product experience, or anticipated by examining known variables. The manufacturer may give it as a list of a product's or segment's unwavering quality and, at times, to give customers thought of how much service to plan for.

5 Main maintenance pointers with MTTR and MTBF 

MTBF - Mean Time Between Failures 

The principal maintenance markers are MTTR and MTBF. The MTBF or mean time between failures, as the name suggests, demonstrates the average all out time of smooth operation between failures of machines that can be fixed. That is: This is the place we can gauge the unwavering quality of the machine.

A machine runs for 12 hours in multi-day. In those 12 hours, she has 3 issues. On the primary blame, it took 5 minutes for a fix, on the second 10 and on the third 15 minutes. Including an aggregate of 30 minutes of a fix, how about we calculate the MTBF:

MTBF = (12 * 60 - 30)/3 = 230 minutes 

The higher the outcome, the more noteworthy the unwavering quality of your gadget. This esteem demonstrates to us that amid the entire 10 hour time frame the production must be programmed and consider that at regular intervals there will be a failure. Leaving the gadget inaccessible for production. Also, this will rehash itself 3 times throughout 12 hours.

Mean Time To Repair - MTTR 

The MTTR maintenance management computer program marker or average fix time, just as the name itself, discloses to us the average time workers will take to get the machine ready for action again.

The machine works a sum of 12 hours in multi-day, showing 3 flaws. The first with 5 minutes, second with 10 and the third 15, including an aggregate of 30 minutes spent. At that point we will have:

MTTR = (5 + 10 + 15)/3 = 10 minutes 

The average time spent on fixes is 10 minutes. Production must be scheduled to acknowledge an average of 10 minutes of fix to the machinery.


Educates about mtbf mttr availability calculation. This is to what extent the machine is accessible to work as programmed. This esteem is the significant objective of maintenance management. The higher this esteem, the better it will be.

Give us a chance to use for instance the estimations of the MTBF and MTTR maintenance markers. At that point it will be:

A = MTBF/(MTBF + MTTR) x 100%

At where

A = 230/(230 + 10) x 100 = 95.83%

With this aftereffect of 95.83% availability, the maintenance group can work to control and improve this number to an ever increasing extent.

MPD - Compliance with predictive maintenance plans 

The MPD calculation is utilized to check whether the predictive maintenance plan is being met or not. It depends on the tasks performed in the predictive maintenance plan separated by the planned activities of the preventive maintenance plan.

It is vital that they are duplicated by 100 with the goal that we find in percentage structure.

Thusly we have: 

MPD = Performed Scheduled Preventive Maintenance/Predictive Maintenance Plan tasks performed * 100

MP - Compliance with preventive maintenance plans 

The calculation of the MP serves to check if the preventive maintenance plan is being satisfied or not. It is fundamentally the same as MPD and the best approach to calculating it is by partitioning the preventive maintenance tasks by the scheduled activities of the preventive maintenance plan. Additionally, duplicating by 100 so we see the percentage.
