Re: MTBF and MTBR
Dear Hitesh,
Find the details required by you :- MTBF - It stands for MEAN TIME BETWEEN FAILURE for any equipment.This factor is calculated with the help of data of past performance. MTBF depends on quality of maintenance and quality of operations. Higher the MTBF, better it speaks for the O & M of the equipment.Good coordination between Operations and Maint is necessary to achieve highr MTBF. MTBF is normally monitored for critical and big equipments like turbines,compressors etc MTTR - It stands for MEAN TIME TO REPAIR for any equipment. This factor is calculated with the help of past data and making a repair model based on optimun use of resources. This factor is a true reflection of quality of maintenance. Lower the MTTR, better it is. As in case of MTBF, this factor is monitored for large and crtitical eqpt. Regarding projects, you are right. The time and cost overruns mean overshooting the originally estimated time and cost estimates. Hope this helps ;)
