Peb yuav sib tham txog 3 ntawm lawv: MTTR (Lub Sijhawm Kho Kom Zoo) MTBF (Txhais Lub Sijhawm Ua Tsis Taus) MTTF (Lub Sijhawm Ua Tsis Tau)
MTTR MTTF thiab MTBF yog dab tsi?
MTBF thiab MTTF ntsuas lub sijhawm cuam tshuam txog kev ua tsis tiav, tab sis lub sijhawm kho(MTTR) ntsuas lwm yam tag nrho: nws yuav siv sijhawm ntev npaum li cas kom tau txais cov khoom lag luam ua tsis tiav dua. Raws li MTTR txhais tau hais tias cov khoom yog lossis yuav raug kho, MTTR tsuas yog siv rau MTBF kev kwv yees.
Koj suav MTBF los ntawm MTTF li cas?
Qhov kwv yees ntawm MTBF yog: MTBF=(10500) / 2=2, 500 teev / tsis ua haujlwm. Whereas rau MTTF MTTF=(10500) / 10=500 teev / tsis ua haujlwm. Yog tias MTBF paub, ib tus tuaj yeem xam qhov ua tsis tiav raws li qhov hloov pauv ntawm MTBF.
MTBF puas zoo ib yam li MTTF?
Technically, MTBF yuav tsum tau siv tsuas yog hais txog cov khoom kho tau, thaum MTTF yuav tsum siv rau cov khoom tsis kho. Txawm li cas los xij, MTBF feem ntau yog siv rau ob qho tib si kho thiab tsis kho. Failure In Time (FIT) yog lwm txoj hauv kev tshaj tawm MTBF.
MTTR thiab MTBF yog dab tsi?
MTBF=Total uptime /of Breakdowns. Kev tshuaj xyuas MTBF pab cov tuam tsev saib xyuas cov tswv yim txog yuav ua li cas txo lub sij hawm ntawm kev ua tsis tiav. Ua ke, MTBF thiab MTTR txiav txim siab txog sijhawm. Txhawm rau xam lub sijhawm ua haujlwm nrog ob qhov ntsuas no, siv cov qauv hauv qab no: Uptime=MTBF / (MTBF + MTTR)
