MTBF is an abbreviation for "mean time between failures" and is often used by companies to try and improve. A person can calculate the MTBF by dividing the sum of operational hours by the number of failures.

What MTBF means?
mtbf = mean time between failure
What is the relationship between reliability and failure rate?
MTBF = 1/failure rate R(t) = e (-t/MTBF) http://www.vicorpower.com/documents/quality/Rel_MTBF.pdf
What is MTBF and MTTR?
Mean Time to Repair and Mean Time Between Failure:They are Maintenance and Reliability predictors.
If you were born Aug 1975 how old would you be this aug?
Old enough to calculate your own age (new person) This August you would turn 34.
How you calculate a person is genius?
you take an IQ test!
What is the relation between MTTR and MTBF?
Mtbf=mttf+mttr
What MTBF means?
mtbf = mean time between failure
What is the relation between mtbf mttf and mttr?
Mtbf=mttf+mttr
What is the relationship between reliability and failure rate?
MTBF = 1/failure rate R(t) = e (-t/MTBF) http://www.vicorpower.com/documents/quality/Rel_MTBF.pdf
Full form of MTBF?
Mean time before failure
IS MTBF part of consideration if we want purchase a new equipments?
Yes. It stands for mean time between failure so the greater the MTBF, greater will be the longevity or lifetime of the equipment between two successive failures
What is MTBF and MTTR?
Mean Time to Repair and Mean Time Between Failure:They are Maintenance and Reliability predictors.
What is MTTR and MTBF explain?
Mean Time to Repair and Mean Time Between Failure:They are Maintenance and Reliability predictors.
How would a person calculate a prorated contract?
Calculate the amount of money you make per day, then multiply it with the amount of workdays you have completed and that should give you the prorated contract.
If you were born Aug 1975 how old would you be this aug?
Old enough to calculate your own age (new person) This August you would turn 34.
How do you calculate the force exerted by a person on the floor?
To calculate the force exerted by a person on the floor, we can use Newton's second law of motion: force = mass × acceleration. In this case, the mass would be the person's weight (mass = weight / acceleration due to gravity), and the acceleration would be the force of gravity acting on the person (acceleration = 9.8 m/s^2). By multiplying the person's weight by the acceleration due to gravity, we can determine the force exerted by the person on the floor.
What is the difference between price and cost?
From a Seller's perspective: Price is what you sell something for, cost is what you paid for it or what it cost to produce it. The difference is referred to as margin or gross profit.From a Buyer's perspective: Price is what you initially pay for an item. Cost is what it takes to maintain the item until it reaches Mean Time Between Failure (MTBF) also referred to as Life Expectancy (see UL rating to get MTBF). Example: Company Apurchases a surveillance system (whose DVR and Cameras have an MTBF rating of 6 years) for a price of $50,000.00. Company B purchases a surveillance system (whose DVR and Cameras have an MTBF rating of 18 years) for a price of $75,000.00. Based on the MTBF ratings Company A will have to purchase their surveillance system three times for an actual cost of $150,000.00 over the 18 years. Then you factor the time value of money on your savings for your final evaluation on Price versus Cost. Assuming a 6% interest rate over 18 years you would have a total of $75,000.00. Company A's Cost is $25,000 more (not counting the company labor to coordinate the system change) So it is important to evaluate MTBF in order to make the most economical purchase.
