Keskmine t\u00f5rgetevaheline t\u00f6\u00f6aeg (MTBF) on remonditava seadme keskmine t\u00f6\u00f6aeg \u00fche t\u00f5rke kohta.<\/strong> Tootmismasina MTBF-i arvutamiseks jaga selle t\u00f6\u00f6tundide koguarv samal vaatlusperioodil registreeritud seadmet\u00f5rgete arvuga:<\/p>\n\n\n

MTBF = t\u00f6\u00f6aeg kokku \u00f7 t\u00f5rgete arv<\/strong><\/p>\n\n\n

Kui masin on t\u00f6\u00f6tanud 160 tundi ja selle aja jooksul on esinenud neli t\u00f5rget, on vaadeldud MTBF 40 t\u00f6\u00f6tundi. See ei t\u00e4henda, et masin l\u00e4heb rikki iga 40 tunni j\u00e4rel v\u00f5i et hooldus vahetult enne 40. t\u00f6\u00f6tundi hoiab j\u00e4rgmise t\u00f5rke \u00e4ra.<\/p>\n\n\n

Oluline on k\u00fcsida, mida t\u00f5rgete muster soovitab uurida ja muuta. Kui hooldus- ja tootmismeeskond on hooldus- v\u00f5i remondit\u00f6\u00f6 kokku leppinud, peab sellest tulenev seisak kajastuma ka tellimuste ajakavas. SkyPlanner APS seob tootmisv\u00f5imsuse muutuse t\u00f6\u00f6de ja tarnekuup\u00e4evadega, mida see m\u00f5jutab. Nii ei pea sa hooldust\u00f6\u00f6de loendit masinate eraldi t\u00f6\u00f6j\u00e4rjekordadega ise koosk\u00f5lla viima.<\/p>\n\n\n

M\u00e4\u00e4ratle, mida sinu MTBF-i arvutus tegelikult m\u00f5\u00f5dab<\/h2>\n\n\n

Jagamistehe on lihtne. Rohkem t\u00e4helepanu n\u00f5uab see, et t\u00f6\u00f6tundide ja t\u00f5rgete arvestus l\u00e4htuks samadest alustest. Enne aruande v\u00e4ljav\u00f5tmist lepi andmete registreerijatega kokku neljas asjas.<\/p>\n\n\n

M\u00e4\u00e4ratle vaadeldav seade<\/h3>\n\n\n

Alusta konkreetsest masinast v\u00f5i selgelt piiritletud s\u00fcsteemist. T\u00f6\u00f6tluskeskus, selle spindel ja kogu mehaanikat\u00f6\u00f6tluse osakond on erineva ulatusega m\u00f5\u00f5tmisobjektid.<\/p>\n\n\n

Kui m\u00f5\u00f5dad kogu masinat, loetakse spindli t\u00f5rge masina t\u00f5rkeks juhul, kui see takistab masinal n\u00f5utud t\u00f6\u00f6d teha. Spindlikomponendi v\u00e4ljavahetamine ja masina uuesti kasutusele v\u00f5tmine ei muuda masinat mitteremonditavaks tooteks.<\/p>\n\n\n

M\u00f5\u00f5ta saab ka kogu liini, kuid siis tuleb liini t\u00f5rge m\u00e4\u00e4ratleda kui liini suutmatus t\u00e4ita n\u00f5utud funktsiooni. K\u00f5igi komponentide h\u00e4irete liitmisel v\u00f5id sama liiniseisaku kohta arvesse v\u00f5tta mitu kirjet.<\/p>\n\n\n

M\u00e4\u00e4ratle t\u00f5rge, mitte lihtsalt seiskumine<\/h3>\n\n\n

M\u00e4\u00e4ra kindlaks n\u00f5utud funktsioon ja s\u00fcndmus, mille korral loetakse see funktsioon kadunuks. Seadmerike, mille t\u00f5ttu masin ei vasta enam n\u00f5utud t\u00f6\u00f6tingimustele, v\u00f5ib kvalifitseeruda t\u00f5rkeks ka siis, kui masin pole t\u00e4ielikult v\u00e4lja l\u00fclitunud.<\/p>\n\n\n

Planeeritud hooldus, tavap\u00e4rane tootevahetusega kaasnev \u00fcmberseadistus, operaatori puudumine ja materjali ootamine ei ole automaatselt seadmet\u00f5rked. Hoia need ajakaod n\u00e4htaval, kuid \u00e4ra lisa neid t\u00f5rgete arvu.<\/p>\n\n\n

Lepi kokku, kuidas k\u00e4sitleda l\u00fchiajalisi t\u00f5rkeid ja korduvaid l\u00e4htestamisi. \u00dche k\u00f5rvaldamata rikke ajal tekkinud mitut h\u00e4irekirjet ei tohiks lugeda mitmeks s\u00f5ltumatuks t\u00f5rkeks. Uus t\u00f5rge p\u00e4rast t\u00f6\u00f6v\u00f5ime tegelikku taastamist on uus s\u00fcndmus. S\u00e4ilita algsed \u00fcksikasjad, et saaksid korduvaid t\u00f5rkeid uurida, mitte neid aruandluses kehtestatud l\u00e4vendi abil peita.<\/p>\n\n\n

Vali t\u00f6\u00f6aja arvestuse alus<\/h3>\n\n\n

Selles juhendis kasutatakse tegelikul t\u00f6\u00f6ajal p\u00f5hinevat MTBF-i<\/strong>: arvesse l\u00e4hevad tunnid, mil vaadeldav seade m\u00e4\u00e4ratletud ulatuses tegelikult t\u00f6\u00f6tab. Remondiaeg ja muu aeg, mil seade ei t\u00f6\u00f6ta, lugejasse ei kuulu. Tulemus ei ole keskmine kalendriaeg \u00fche rikke tekkimisest j\u00e4rgmiseni.<\/p>\n\n\n

T\u00e4psusta, mida t\u00f6\u00f6aja arvestuseks kasutatav signaal h\u00f5lmab. Sissel\u00fclitatud olekut m\u00f5\u00f5tev tunniloendur, t\u00f6\u00f6ts\u00fckli k\u00e4igusoleku signaal ja mehitatud vahetuste kalender v\u00f5ivad anda erineva kogutulemuse. Kui sinu seadme koormust iseloomustab t\u00f6\u00f6tundide asemel paremini ts\u00fcklite v\u00f5i k\u00e4ivituste arv, j\u00e4lgi seda n\u00e4itajat t\u00f6\u00f6tundide k\u00f5rval. \u00c4ra eelda, et need m\u00f5\u00f5dikud on omavahel asendatavad.<\/p>\n\n\n

Kasuta \u00fchtset vaatlusperioodi<\/h3>\n\n\n

Kasuta t\u00f6\u00f6tundide ja t\u00f5rgete arvestuses sama aruandeperioodi algust ja l\u00f5ppu. Loe t\u00f5rkeid nende tekkimisaja j\u00e4rgi selle perioodi sees. Kui rike tekkis eelmisel kuul, ei ole sel kuul l\u00f5ppenud remont uus t\u00f5rge.<\/p>\n\n\n

Arvesta kogu tegelikku t\u00f6\u00f6aega vaatlusperioodi sees, sealhulgas aega, millele ei j\u00e4rgne enne aruandeperioodi l\u00f5ppu t\u00f5rget. M\u00f5\u00f5dad perioodi jooksul kogunenud t\u00f6\u00f6aega, mitte ainult neid l\u00f5ppenud t\u00f6\u00f6perioode, mis juhtusid l\u00f5ppema t\u00f5rkega. Perioodi seisakuaja kogusummasse lisa ainult selle perioodi sisse j\u00e4\u00e4vad tunnid, mil seade ei olnud kasutatav. Kui rike ulatub \u00fcle aruandeperioodi piiri, s\u00e4ilita eraldi t\u00e4ielik s\u00fcndmuse ja t\u00f6\u00f6v\u00f5ime taastamise kirje.<\/p>\n\n\n

S\u00e4ilita iga t\u00f5rke kohta masina ID, t\u00f5rke tekkimise aeg, t\u00f6\u00f6v\u00f5ime taastamise aeg, t\u00e4heldatud s\u00fcmptom v\u00f5i t\u00f5rkeviis ning asjakohased t\u00f6\u00f6tingimused. Need \u00fcksikasjad aitavad keskmist n\u00e4itajat selgitada.<\/p>\n\n\n

Arvutus on j\u00e4rgmine:<\/p>\n\n\n

160 t\u00f6\u00f6tundi \u00f7 4 t\u00f5rget = 40 t\u00f6\u00f6tundi t\u00f5rke kohta<\/strong><\/p>\n\n\n

Kui alustad mehitatud aja kogusummast, lahuta esmalt aeg, mil masin ei t\u00f6\u00f6tanud: 200 \u2212 12 \u2212 8 \u2212 10 \u2212 10 = 160 tundi. Kui sinu andmeallikas n\u00e4itab juba 160 tegelikku t\u00f6\u00f6tundi, kasuta seda arvu otse. Seisakuaja uuesti lahutamine annaks tegelikust v\u00e4iksema MTBF-i.<\/p>\n\n\n

N\u00e4ide n\u00e4itab ka seda, miks \u00fcksnes vahetuste kalendrist ei piisa. Kui jagada 200 mehitatud tundi neljaga, saaks tulemuseks 50 tundi t\u00f5rke kohta, kuid see h\u00f5lmaks ka aega, mil masin ei t\u00f6\u00f6tanud.<\/p>\n\n\n

Esita tulemus koos taustandmetega: \u201eMasin MC-01, aruandeperiood, 160 t\u00f6\u00f6tundi, neli t\u00f5rget, vaadeldud MTBF 40 tundi.\u201c Teise perioodiga v\u00f5rdlemisel on lugeja ja t\u00f5rgete arv sama olulised kui l\u00f5pptulemus.<\/p>\n\n\n

Kuidas k\u00e4sitleda t\u00f5rgete puudumist ja mitme masina andmeid tulemust moonutamata<\/h2>\n\n\n

Mis siis, kui t\u00f5rkeid ei olnud?<\/h3>\n\n\n

\u00c4ra jaga nulliga ega esita l\u00f5pmatut MTBF-i t\u00e4iusliku t\u00f6\u00f6kindluse t\u00f5endina. Kirjuta \u201e160 t\u00f6\u00f6tunni jooksul t\u00f5rkeid ei t\u00e4heldatud\u201c, kasutades aruandes tegelikult kogunenud t\u00f6\u00f6aega.<\/p>\n\n\n

See on kasulik teave, kuid ei ole samav\u00e4\u00e4rne mitme aasta pikkuse t\u00f5rgeteta t\u00f6\u00f6ga. Statistilise alumise usalduspiiri leidmiseks on vaja statistilist mudelit ja valitud usaldusnivood. Tavap\u00e4rases tootmis\u00fclevaates on ausam esitada t\u00f5rgete arvuna null ja lisada vaadeldud t\u00f6\u00f6aeg, mitte m\u00f5elda v\u00e4lja punkthinnangut.<\/p>\n\n\n

Mis siis, kui andmed p\u00e4rinevad mitmelt masinalt?<\/h3>\n\n\n

Kui v\u00f5rreldavate masinate koondamine \u00fchte r\u00fchma on p\u00f5hjendatud, kasuta valemit masinate t\u00f6\u00f6tunnid kokku \u00f7 t\u00f5rked kokku<\/strong>. \u00c4ra jaga \u00fchist kalendriperioodi k\u00f5igi masinate t\u00f5rgete arvuga ega v\u00f5ta masinate MTBF-v\u00e4\u00e4rtustest kaalumata keskmist.<\/p>\n\n\n

V\u00f5tame n\u00e4iteks kaks v\u00f5rreldavat masinat, mille andmeid registreeritakse samade reeglite j\u00e4rgi. \u00dchel koguneb 160 t\u00f6\u00f6tundi ja neli t\u00f5rget, teisel 240 t\u00f6\u00f6tundi ja kaks t\u00f5rget. Koondtulemus on 400 \u00f7 6 ehk ligikaudu 66,7 t\u00f6\u00f6tundi t\u00f5rke kohta, mitte arvude 40 ja 120 lihtne keskmine, mis oleks 80.<\/p>\n\n\n

S\u00e4ilita ka iga masina eraldi tulemus. Koondn\u00e4itaja v\u00f5ib varjata masinat, mis p\u00f5hjustab tootmises k\u00f5ige rohkem probleeme. Erineva konstruktsiooni, vanuse v\u00f5i t\u00f6\u00f6\u00fclesannetega seadmed v\u00f5ivad vajada eraldi r\u00fchmi, mitte \u00fcht kogu tehast h\u00f5lmavat t\u00f6\u00f6kindluse n\u00e4itajat.<\/p>\n\n\n

Enne tegevuse valimist t\u00f5lgenda MTBF-i<\/h2>\n\n\n

Suurem vaadeldud MTBF t\u00e4hendab, et m\u00e4\u00e4ratletud ulatuses on \u00fche t\u00f6\u00f6tunni kohta v\u00e4hem arvesse v\u00f5etud t\u00f5rkeid. Kas see n\u00e4itab paranemist, s\u00f5ltub sellest, mis veel muutus.<\/p>\n\n\n

V\u00f5rdle v\u00f5rreldavat<\/h3>\n\n\n

V\u00f5rdle perioode, mille puhul on t\u00f5rked, t\u00f6\u00f6aja arvestus ja vaadeldava seadme piirid m\u00e4\u00e4ratletud \u00fchtemoodi. Seej\u00e4rel vaata, millist t\u00f6\u00f6d masin teeb. Kui masin toodab lihtsamat tootevalikut ja t\u00f6\u00f6tab teistsuguse koormusega, ei t\u00f5enda see iseenesest, et hoolduse muudatus andis tulemuse.<\/p>\n\n\n

N\u00e4ita trendi k\u00f5rval ka tegelikku t\u00f6\u00f6aega ja t\u00f5rgete arvu. \u00dcks l\u00fchike periood, mille jooksul esineb vaid \u00fcks t\u00f5rge, v\u00f5ib keskmist j\u00e4rsult muuta. Pikem vaatlusperiood aitab, kuid erinevate t\u00f6\u00f6tingimustega aastate \u00fchendamine v\u00f5ib varjata hiljutist halvenemist. Vaata lisaks kogu perioodi keskmisele ka viimase aja suundumust ja selle taga olevaid tingimusi.<\/p>\n\n\n

K\u00f5igile tootmismasinatele sobivat \u201ehead MTBF-i\u201d ei ole. Kasulik sihtv\u00e4\u00e4rtus l\u00e4htub v\u00f5rreldavatest varasematest andmetest, n\u00f5utavast t\u00f6\u00f6koormusest ja t\u00f5rke tagaj\u00e4rgedest. Kergesti asendatava masina k\u00f5rge n\u00e4it v\u00f5ib m\u00f5jutada tarnekindlust v\u00e4hem kui sagedased katkestused ainsal masinal, mis suudab teha kriitilist operatsiooni.<\/p>\n\n\n

\u00c4ra kasuta keskmist j\u00e4rgmise t\u00f5rkeni j\u00e4\u00e4nud aja m\u00f5\u00f5dupuuna<\/h3>\n\n\n

40-tunnine MTBF ei n\u00e4ita j\u00e4rgmise t\u00f5rke aega ega masina j\u00e4relej\u00e4\u00e4nud eluiga. T\u00f5rked v\u00f5ivad esineda l\u00e4hestikku ning m\u00f5ni t\u00f5rgeteta t\u00f6\u00f6periood v\u00f5ib olla keskmisest palju pikem.<\/p>\n\n\n

Samuti ei piisa \u00fcksnes MTBF-ist ennetava hoolduse intervalli p\u00f5hjendamiseks. Sobiv tegevus s\u00f5ltub t\u00f5rke tekkemehhanismist, seadme seisundi kohta kogutud andmetest, seadme juhistest ja t\u00f5rke tagaj\u00e4rgedest. N\u00e4iteks vananemisega seotud kulumine ja aeg-ajalt esinev saastumine vajavad erinevat uurimist. \u00dcldine keskmine ei n\u00e4ita, kummaga on tegu.<\/p>\n\n\n

Kui tulemus halveneb, otsi \u00fcles selle taga olevad t\u00f5rked ja k\u00fcsi t\u00e4psemalt: milline t\u00f5rkeliik kordub, millistes tingimustes ja milline muudatus selle k\u00f5rvaldaks? Seej\u00e4rel kontrolli, kas probleem kordub p\u00e4rast sekkumist v\u00f5rreldavates t\u00f6\u00f6tingimustes.<\/p>\n\n\n

Vaata t\u00f5rgete sagedust koos kaotatud ajaga<\/h3>\n\n\n

MTBF ei n\u00e4ita, kui kaua tootmine p\u00e4rast t\u00f5rget seisab. Kahe sama MTBF-iga masina m\u00f5ju tellimuste t\u00e4itmisele v\u00f5ib olla v\u00e4ga erinev, kui \u00fcks naaseb kiiresti t\u00f6\u00f6sse, teine aga ootab spetsialisti v\u00f5i varuosa.<\/p>\n\n\n

Vaata keskmise k\u00f5rval ka t\u00f5rgetest tingitud seisakute kogukestust ja pikemaid \u00fcksikuid katkestusi. J\u00e4lgi ka m\u00f5ju t\u00f6\u00f6 j\u00e4rgmistele etappidele. L\u00fchike katkestus vahetult enne kriitilise operatsiooni ainsat vaba ajavahemikku v\u00f5ib tarnet m\u00f5jutada rohkem kui pikem seisak, mille j\u00e4rel on piisavalt aega kaotatu tasa teha.<\/p>\n\n\n

MTBF-i, MTTR-i ja MTTF-i erinevused<\/h2>\n\n\n

Need m\u00f5\u00f5dikud vastavad erinevatele k\u00fcsimustele. M\u00e4rgi selgelt, millist seadet v\u00f5i komponenti m\u00f5\u00f5dik h\u00f5lmab ja kuidas aega arvestatakse, selle asemel et k\u00e4sitleda l\u00fchendeid samav\u00e4\u00e4rsete n\u00e4itajatena.<\/p>\n\n\n

Tootmise planeerimisel on oluline kogu aeg, mil masinat ei saa kasutada, isegi kui remondiaruandes arvestatakse ainult vahetult remondile kulunud aega. Komponendi vahetamine v\u00f5ib v\u00f5tta v\u00e4he aega, kuid masin v\u00f5ib seista palju kauem, kuni meeskond hangib vajaliku komponendi ja teeb tootmise j\u00e4tkamiseks n\u00f5utavad kontrollid.<\/p>\n\n\n

See eristus aitab v\u00e4ltida levinud planeerimisviga: keskmist remondikestust ei saa v\u00f5tta lubadusena, et iga tulevane rike k\u00f5rvaldatakse sama aja jooksul.<\/p>\n\n\n

Kasuta t\u00f6\u00f6kindluse anal\u00fc\u00fcsi tulemusi SkyPlanneris tootmisotsuste tegemiseks<\/h2>\n\n\n

Oletame, et uurimise tulemusel lepib hooldusmeeskond j\u00e4rgmiseks kolmap\u00e4evaks kokku kolmetunnise hooldust\u00f6\u00f6 t\u00f6\u00f6tlemiskeskuses. See on tehnilise otsuse alusel valitud hooldusaeg, mitte 40-tunnise MTBF-i p\u00f5hjal ennustatud t\u00f5rke kuup\u00e4ev.<\/p>\n\n\n

See kokkulepe muudab klienditellimuste t\u00e4itmiseks kasutada olevat tootmisv\u00f5imsust. Kui see j\u00e4\u00e4b ainult hoolduskalendrisse, v\u00f5idakse tootmisplaanis j\u00e4tkuvalt m\u00e4\u00e4rata t\u00f6id masinale, mida sel ajal kasutada ei saa. Planeerija avastab vastuolu alles siis, kui p\u00fc\u00fcab n\u00e4dala tarneid graafikus hoida.<\/p>\n\n\n

SkyPlanneris sisesta kokkulepitud ajavahemik<\/a> t\u00f6\u00f6keskuse erandina<\/strong>. Erand muudab ressursi selleks ajaks k\u00e4ttesaamatuks. Seej\u00e4rel saab SkyPlanneri ajastamise tehisintellekt Arcturus ajastatavate operatsioonide ajad muutunud tootmisv\u00f5imsuse j\u00e4rgi \u00fcmber arvutada, arvestades seadistatud t\u00f6\u00f6keskusi, vahetusi, operatsioonide kestusi, s\u00f5ltuvusi, prioriteete ja lukustusi. Saadud j\u00e4rjestust n\u00e4ed Gantti diagrammil.<\/p>\n\n\n

Kolmap\u00e4evase hooldust\u00f6\u00f6 puhul kontrolli, kas ootel t\u00f6\u00f6tlemisoperatsioonide j\u00e4rel j\u00e4\u00e4b endiselt aega j\u00e4rgnevaks kontrolliks ja koostamiseks. Kui t\u00f6\u00f6 suunatakse sobivale alternatiivsele ressursile, kontrolli ka sellele ressursile juba planeeritud t\u00f6id ja nendega seotud lubadusi. Vabast ajast on kasu ainult siis, kui operatsiooni saab seal tegelikult teha ja ka \u00fclej\u00e4\u00e4nud t\u00f6\u00f6etapid mahuvad ajakavasse.<\/p>\n\n\n

Seep\u00e4rast on SkyPlanner kasulik j\u00e4rgmine samm, kui t\u00f6\u00f6kindluse parandamiseks tehtav t\u00f6\u00f6 muudab masinate saadavust. Tehnilised ja \u00e4rilised otsused j\u00e4\u00e4vad sinu teha; Arcturus teeb seotud t\u00f6\u00f6de ajastamiseks vajalikud arvutused<\/a>. T\u00f6\u00f6j\u00e4rjekordade \u00fcmbertegemisele kulub v\u00e4hem aega ning tootmine ja m\u00fc\u00fck saavad \u00fchise aluse veel lahtiste tarneotsuste tegemiseks.<\/p>\n\n\n

Kui kokkulepitud hooldusaeg muutub, ajakohasta see ka plaanis. Arvuta ajakava uuesti ja vaata \u00fcle m\u00f5jutatud tarnelubadused, selle asemel et minna j\u00e4rgmisse vahetusse aegunud eeldusega masina saadavuse kohta.<\/p>\n\n\n

Vaata, kuidas \u00fche masina saadavus sinu tarneid m\u00f5jutab<\/h2>\n\n\n

Kasulik MTBF-i anal\u00fc\u00fcs annab lisaks arvule ka selgema tegevussuuna. M\u00e4\u00e4ratle anal\u00fc\u00fcsi aluseks olevad andmed, uuri olulisi t\u00f5rkeid ja kanna kokkulepitud tootmisv\u00f5imsuse muudatus plaani, mille j\u00e4rgi tootmine tegelikult t\u00f6\u00f6tab.<\/p>\n\n\n

Vali SkyPlanner, kui pead selle muudatusega arvestama seotud klienditellimuste ajastamisel, ilma et peaksid iga seotud masina t\u00f6\u00f6j\u00e4rjekorda k\u00e4sitsi parandama. SkyPlanner liidestub avatud REST API kaudu mis tahes ERP- v\u00f5i MES-s\u00fcsteemiga, nii et ajastamise t\u00e4iustamisel saad tugineda olemasolevatele tellimus- ja tootmisandmetele.<\/p>\n\n\n

Broneeri SkyPlanneri demo<\/a> ja v\u00f5ta aluseks \u00fcks masin, selle kokkulepitud seisakuaeg ning sellel t\u00e4idetavad tellimused. Palu n\u00e4idata, milliste operatsioonide ajad muutuvad, kuidas see m\u00f5jutab j\u00e4rgnevaid etappe ja milliste tarnelubaduste puhul tuleb otsus teha. Kui eelistad esmalt ise tutvuda, proovi SkyPlannerit demoandmetega<\/a> ja vaata, kuidas tootmisv\u00f5imsuse muutus ajakava \u00fcmber kujundab.<\/p>\n\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
