Ukusebenza koPhuhliso oluPhezulu (OEE)

Yisebenzise njengeNgxenye yoPhuculo oluPhezulu lokuPhumelela koPhuculo

IiNkampani eziye zazalisekisa i-Total Total Maintenance (TPM), ngokuqhelekileyo zenza oku njengenxalenye yokuphunyezwa kwamanye amanyathelo okuphuculwa kwemveliso ezifana ne-Six Sigma, i- Lean Manufacturing , ne- Quick Response Manufacturing . Xa ama shishini afuna ukuvavanya impumelelo ehambelanayo neenkqubo zazo ze-TPM, bahlala besetyenziselwa imilinganiselo yamanyathelo abizwa ngokuba yi-Overall Equipment Effectiveness (OEE).

Isixhobo esipheleleyo sesebenza ngetekethi yamatriki engasetyenziswa ukulinganisa ukusetyenziswa komsebenzi wokuvelisa okanye isixhobo.

Imetriki ingasetyenziselwa imihla ngemihla ukuchonga indlela izixhobo ezenza ngayo kodwa zingasetyenziselwa njongo njongo inqwenela ukuyenza.

Xa inkampani ibheka izixhobo zokusebenza kakuhle, kukho indawo ezintandathu apho inkunkuma ingenzeka khona; izixhobo zokungaphumeleli, ukusetha, kunye nokulungiswa, ukuxhamla, ukuhlaziya kunye nokusebenza kwakhona, ukusetyenziswa kwejubane elinciphileyo, kunye nokulahleka kokuqalisa.

• Izixhobo ezihlulekayo

  Ezi zintlupheko ezingalindelekanga ezenzeka ngaphandle kwesixwayiso kwaye zenze ukuba ummi umiswe. Iyakuchukumisa kakhulu ishedyuli yokuvelisa kunye nokuthengiswa kwabathengi. Ukuba ukuhluleka akukwazi ukulungiswa ngokukhawuleza, isixhobo esitsha singadinga ukuthengwa esinokubangela ubunzima bezezimali kwiinkampani ezincinane okanye eziphakathi.

• Ukuseta kunye nohlengahlengiso

  Isixhobo sokuphuhla kwezixhobo kwakhona senzeka xa uomatshini bephukile phantsi ekupheleni komsebenzi wokuvelisa, kwaye izixhobo ezitsha zilungiselelwa ukuqhutywa kwemveliso elandelayo. Nangona eli xesha liphantsi lifakwe kwishedyuli yokuvelisa, nayiphi na ixesha elongezelelweyo elifunekayo kwi-setup ngenxa yokulungiswa, akunokuthi, kwaye oku kunokulibazisa ishedyuli yokuvelisa.

• Idling

  Ishedyuli yokuvelisa ilindele ukuba izixhobo ziqhube kwijubane eliphezulu. Umatshini unokunciphisa isivinini xa kukho imicimbi emincinci engalungiswa ngumsebenzisi womatshini. Kubalulekile ukuba umsebenzisi aqaphele xa umatshini osebenza ngaphantsi kwezinga eliphezulu kakhulu njengoko kunokuchaphazelekayo kwishedyuli yokuvelisa.

• I-Scrap neRework

  Ukuba umatshini awusebenzi kwizinga eliphezulu liyakwazi ukuvelisa izinto ezingaphantsi kwezinga elimkelekileyo lomgangatho kwaye kuya kufuneka zidityaniswe okanye zenziwe kwakhona. Akukuphela nje ukulahlwa kwexesha kunye nezixhobo, kodwa kunokuchaphazela kakhulu ishedyuli yokuvelisa kunye nemihla yokuhanjiswa kwabaxhasi.

• Ukusebenza kweSantya esinciphileyo

  Isantya sesixhobo sichazwe ngumenzi kunye neenkampani zilindele ukuba isivinini esibhaliweyo sisantya esiza kusebenza kumatshini. Nangona kunjalo, ngaphandle kokuba inkampani ilandele izixhobo kwaye iqinisekise ukuba isebenzayo kwi-specification of the manufacturer, ke kunokwenzeka ukuba umatshini usebenza ngezantsi.

• Ukuqalisa ukulahleka

  Xa kusetyenziswe izixhobo, kukho imicimbi ethile kunye nezinto zokuqala ezivelisiweyo. Ngokomzekelo, kwimveliso yamakhemikhali, iibhetki zokuqala zingenakho umgangatho ofanelekileyo. Nangona ukulahleka kokuseta kufakwe kwishedyuli yokuvelisa, kuthetha ukuthathwa kwexesha kunye nezibonelelo ezinokuncitshiswa.

Kukho izinto ezintathu ezisetyenzisiweyo ekubalweni koPhuhliso lweeMpahla eziPhezulu. Ezi zizinga lokufumaneka, izinga lokusebenza, kunye nezinga lezinga eliphezulu.

• Izinga lokuFumaneka

  Izinga lokufumaneka lixesha ixesha le sixhobo lisebenza, ngokubhekisele kwixesha elingaba liqhuba. Ukunciphisa izinga lokufumaneka libonakaliso lwezixhobo ezingaphumeleli kunye nemiba malunga nokusekwa kunye nokulungiswa.

• Izinga lomsebenzi

  Isantya sokusebenza ubungakanani bezinto eziveliswe ngexesha lokuhamba, ngokumalunga nobungakanani bento ebenokuveliswa xa kuqwalaselwa abavelisi bezantya ezibhaliweyo zezixhobo. Izinga eliphantsi lokusebenza liyakubonwa ngenxa yokungabikho, ukuyeka okuncinci, kunye nokunciphisa ukusebenza kwejubane.

• Umgangatho woMgangatho

  Umgangatho wemgangathiso ngumlinganiselo wempahla eyamkelekileyo ngokumalunga nomyinge wezinto eziphathekayo. Izinga eliphantsi kwezinga eliphezulu libonisa ukulahleka kokuqala kunye nemali yezinto eziphathekayo.

Xa inkampani kuqala isebenzisa i-metrics ye-OEE, ibona ukusebenza kwezixhobo zazo. Ngoko ke banalo ulwazi abanokukubeka kuzo iinjongo zokuphucula izityalo zabo. Ngokuphucula ukufumaneka, ukusebenza kunye namazinga omgangatho, inkampani inokunciphisa inkcitho yabo kulondolozo kunye nezinto ezibonakalayo kunye nokuphucula amandla abo okuvelisa kunye namaxesha okuhanjiswa kwabaxhasi .
