Mean Time to Repair and Mean Time Between Failure:
They are Maintenance and Reliability predictors.
mtbf = mean time between failure
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.
MTBF = 1/failure rate R(t) = e (-t/MTBF) http://www.vicorpower.com/documents/quality/Rel_MTBF.pdf

The reliability of a system can be assessed by measuring its uptime and downtime, analyzing historical data of failures, conducting failure mode and effects analysis (FMEA), and using metrics such as mean time between failures (MTBF) and mean time to repair (MTTR). Additionally, reliability testing under different conditions and stress levels can help evaluate the system's performance under varying scenarios.
Mean time before failure
maintainability
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
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.
