Lambda System=Lambda tivthaiv 1 + Lambda tivthaiv 2 + Lambda tivthaiv n. MTBF System=1 / Lambda System.
Koj suav MTBF li cas?
Xaiv MTBF, faib tag nrho cov sijhawm ua haujlwm hauv ib lub sijhawm los ntawm tus lej ntawm kev ua tsis tiav uas tshwm sim nyob rau lub sijhawm ntawd. MTBF feem ntau yog ntsuas hauv cov xuab moos. Piv txwv li, ib qho cuab tam yuav tau ua haujlwm rau 1,000 teev hauv ib xyoos.
Koj suav MTBF li cas rau cov khoom siv hluav taws xob?
MTBF. Lub sij hawm nruab nrab ntawm qhov ua tsis tiav yog xam nyob rau hauv cov xuab moos thiab yog qhov kev kwv yees ntawm lub hwj chim qhov kev ntseeg tau. MTBF=1/λ (failure rate). MTTF (txhais tau tias lub sijhawm ua tsis tiav) tuaj yeem hloov pauv hauv qee cov ntaub ntawv rau cov chav uas yuav tsis raug kho.
MTBF kev ntseeg tau suav li cas?
MTBF yog ib qho kev ntsuas tseem ceeb ntawm kev ntseeg siab; qhov siab dua MTBF, qhov siab dua qhov kev ntseeg siab ntawm cov khoom. Qhov kev sib raug zoo no tau piav qhia hauv qhov sib npaug: Kev ntseeg tau=e-(lub sijhawm / MTBF). Muaj ob peb qhov kev hloov pauv ntawm MTBF koj tuaj yeem ntsib.
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.
