Iyini i-MTTF? | Kusho Isikhathi Sokwehluleka
Isingeniso
I-MTTF, noma I-Mean Time To Failure, isilinganiso sesikhathi esimaphakathi uhlelo noma ingxenye engasebenza ngaphambi kokuthi yehluleke. I-MTTF iyimethrikhi ebalulekile emkhakheni wokunakekela kanye nobunjiniyela bokuthembeka, njengoba isiza izinhlangano ziqonde ubude bokuphila okulindelekile kwesistimu kanye nohlelo lokushintshwa noma ukulungiswa.
Ibalwa Kanjani I-MTTF?
I-MTTF ibalwa ngokuhlukanisa isamba sesikhathi sokusebenza sesistimu noma ingxenye ngenani lokwehluleka okwenzeka ngaleso sikhathi. Isibonelo, uma isistimu isebenze amahora angu-1000 futhi ihlangabezane nokuhluleka okuthathu, i-MTTF ingaba amahora angu-1000 / ukwehluleka okungu-3 = amahora angu-333.33.
Kungani I-MTTF Ibalulekile?
I-MTTF ibalulekile ngoba isiza izinhlangano ukuthi ziqonde ubude bokuphila okulindelekile kwesistimu kanye nohlelo lokushintshwa noma ukulungiswa. Lokhu kungase kubaluleke kakhulu kumasistimu abalulekile, njengalawo asekela imisebenzi ebalulekile yebhizinisi noma ukuphepha komphakathi, lapho ukwehluleka kungaba nemiphumela ebalulekile. Ngokuqonda i-MTTF yohlelo oluthile, izinhlangano zingakha amasu okunciphisa isikhathi sokuphumula futhi zithuthukise ukwethembeka.
Ungayithuthukisa Kanjani I-MTTF?
Kunezindlela ezimbalwa izinhlangano ezingathuthukisa ngazo i-MTTF:
- Sebenzisa ukunakekelwa kokuvikela: Ukunakekela okuhleliwe okujwayelekile kungasiza ukunweba ubude besikhathi sokuphila kwesistimu ngokuhlonza nokubhekana nezinkinga ezingase zibe khona ngaphambi kokuba zenzeke.
- Sebenzisa izingxenye zekhwalithi ephezulu: Ukusebenzisa izingxenye zekhwalithi ephezulu kungasiza ekunciphiseni amathuba okuhluleka futhi kunwebe ubude bempilo yesistimu.
- Sebenzisa uhlelo lwezingxenye eziyisipele: Ukuba nengxenye yezingxenye eziyisipele esandleni kungasiza ukunciphisa isikhathi sokuphumula ngokuvumela ukulungiswa ngokushesha uma kwenzeka kwehluleka.
- Sebenzisa amasu okunakekela aqagelayo: Ubuchwepheshe obunjengokuhlaziya ukudlidliza, ukuhlolwa kwe-ultrasonic, nesithombe se-thermal kungasiza ekuboneni ukwehluleka okungase kube khona ngaphambi kokuba kwenzeke, okuvumela ukulungiswa ngesikhathi.
Ngokusebenzisa lawa kanye namanye amasu, izinhlangano zingathuthukisa i-MTTF futhi zinciphise isikhathi sokuphumula.
Isiphetho
I-MTTF, noma I-Mean Time To Failure, isilinganiso sesikhathi esimaphakathi uhlelo noma ingxenye engasebenza ngaphambi kokuthi yehluleke. Kuyimethrikhi ebalulekile emkhakheni wokunakekela kanye nobunjiniyela bokuthembeka, njengoba isiza izinhlangano ziqonde ubude bempilo obulindelekile besistimu kanye nohlelo lokushintshwa noma ukulungiswa. Ngokuqalisa ukunakekelwa kokuvimbela, kusetshenziswa izingxenye zekhwalithi ephezulu, ukusebenzisa uhlelo lwezingxenye eziyisipele, nokusebenzisa amasu okunakekela okubikezela, izinhlangano zingathuthukisa i-MTTF futhi zinciphise isikhathi sokuphumula.
