Lean Manufacturing yog dab tsi?
Lean manufacturing yog ib tug systematic mus kom ze rau ntau lawm, uas yog aims kom txo tau pov tseg, nce efficiency, thiab muab nqi rau cov neeg muas zaub. Txoj kev no pib los ntawm kev Toyota Production System (TPS) thiab tam sim no tau txais kev pom zoo thoob ntiaj teb los ntawm ntau yam kev lag luam thiab kev lag luam.
Lub hom phiaj tseem ceeb ntawm kev tsim khoom lag luam yog ua kom yooj yim rau cov txheej txheem tsim khoom los ntawm kev txheeb xyuas thiab tshem tawm cov haujlwm tsis tsim nyog, cov khoom siv, lossis cov peev txheej uas tsis ncaj qha rau cov khoom lossis kev pabcuam zaum kawg. Qhov no yuav pab txhim kho cov txheej txheem thiab ua kom muaj txiaj ntsig zoo dua.
Cov txiaj ntsig ntawm Lean Manufacturing
Lean manufacturing muaj ntau yam txiaj ntsig rau cov tuam txhab lag luam txhawm rau txhim kho lawv txoj haujlwm. Nov yog tsib qhov txiaj ntsig tseem ceeb:
- Nqi txuag: Lean manufacturing txheeb xyuas thiab tshem tawm cov khoom pov tseg hauv cov txheej txheem, yog li txo cov nqi khiav lag luam. Qhov no tuaj yeem suav nrog cov nqi khoom qis dua, txo kev siv hluav taws xob, thiab ua haujlwm tsawg dua, thaum kawg ua rau cov tuam txhab tau txais txiaj ntsig.
- Nce efficiency: Los ntawm kev txhim kho cov txheej txheem, tshem tawm cov fwj, thiab txhim kho kev ua haujlwm zoo, kev tsim khoom lag luam nce kev ua haujlwm zoo. Qhov no txhais tau tias cov lag luam tuaj yeem tsim tau ntau dua nrog cov peev txheej tib yam lossis tsawg dua, tau txais txiaj ntsig ntau ntawm lawv cov peev txheej.
- Txhim kho qhov zoo: Lean manufacturing tsom rau kev txheeb xyuas thiab daws cov hauv paus ntsiab lus ntawm qhov tsis xws luag, ua rau cov khoom zoo dua. Qhov no txhais tau tias tsawg dua qhov ua yuam kev, ua haujlwm tsawg dua, thiab cov neeg siv khoom txaus siab dua.
- Kev xa khoom sai dua: Lean kev coj ua ua rau lub sij hawm luv luv thiab teb sai dua rau cov neeg siv khoom xav tau. Lub peev xwm los tsim thiab xa cov khoom raws sijhawm tuaj yeem pab cov tuam txhab tau txais txiaj ntsig kev sib tw thiab ua tau raws li cov neeg siv khoom xav tau.
- Ua kom cov neeg ua haujlwm koom nrog: Lean cov hauv paus ntsiab lus txhawb cov neeg ua haujlwm koom nrog, daws teeb meem, thiab kev txhawb zog. Cov neeg ua haujlwm koom nrog muaj kev txhawb siab ntau dua, ua rau muaj kev ua haujlwm zoo dua qub thiab txhim kho txuas ntxiv.
5 Cov Ntsiab Cai ntawm Lean Manufacturing
Dab tsi yog 5 txoj hauv kev ntawm Lean manufacturing? Tsib lub hauv paus ntsiab lus tseem ceeb ntawm lean manufacturing yog:
1/ Tus nqi: Muab qhov tseem ceeb rau cov neeg siv khoom
Thawj lub hauv paus ntsiab lus ntawm Lean Manufacturing yog kom nkag siab thiab xa "Vim Li Cas". Lub tswv yim no yog nyob ib puag ncig kom paub meej tias cov neeg siv khoom muaj nqis tiag tiag hauv cov khoom lossis kev pabcuam. Lean qhov kev xav ntawm tus nqi yog cov neeg siv khoom siv los txheeb xyuas cov yam ntxwv tshwj xeeb, qhov zoo, lossis cov yam ntxwv uas cov neeg siv khoom txaus siab them. Txhua yam uas tsis ua rau cov khoom tseem ceeb no suav tias yog pov tseg.
Kev paub txog "tus nqi" cuam tshuam nrog kev sib koom ua lag luam ua haujlwm nrog cov neeg siv khoom xav tau thiab xav tau. Los ntawm kev nkag siab txog yam uas cov neeg siv khoom xav tau tiag tiag, ib lub koom haum tuaj yeem coj nws cov peev txheej thiab kev siv zog mus rau kev xa tawm raws nraim li cas ntxiv tus nqi, thaum txo qis lossis tshem tawm cov khoom uas tsis ntxiv nqi. Txoj hauv kev no ua kom ntseeg tau tias cov peev txheej tau muab faib ua tau zoo, uas yog ib qho tseem ceeb ntawm Cov Cai Ntawm Lean Manufacturing.
2 / Tus nqi kwj deg: ua kom pom kev ntws ntawm kev ua haujlwm
Txoj cai Lean thib ob, "Value Stream Mapping," ua lub luag haujlwm tseem ceeb hauv kev pab cov koom haum txheeb xyuas thiab tshem tawm cov khoom pov tseg hauv lawv cov txheej txheem.
Tus nqi kwj mapping entails tsim ib qho kev pom kev sawv cev ntawm tag nrho cov txheej txheem, los ntawm keeb kwm ntawm raw cov ntaub ntawv mus rau qhov kawg khoom los yog kev pab cuam muab. Qhov kev pom qhov pom no pab kom nkag siab txog cov txheej txheem ntawm cov dej num koom nrog hauv cov txheej txheem.
Tus nqi kwj dej yog ib qho cuab yeej tseem ceeb rau kev paub qhov txawv ntawm cov dej num uas ua rau muaj txiaj ntsig rau cov khoom lossis kev pabcuam thiab cov uas tsis muaj. Cov dej num uas tsis muaj nqi ntxiv, feem ntau hu ua "muda", tuaj yeem suav nrog ntau hom kev pov tseg, xws li kev tsim khoom ntau dhau, cov khoom muag ntau dhau, tos sijhawm, thiab kev ua haujlwm tsis tsim nyog.
Los ntawm kev txheeb xyuas thiab tom qab ntawd tshem tawm cov peev txheej pov tseg, cov koom haum tuaj yeem txhim kho lawv cov txheej txheem, txo cov sij hawm txhuas, thiab txhim kho kev ua haujlwm tag nrho.
Nov yog ib qho piv txwv ntawm Value Stream Mapping, uas tuaj yeem pab koj nkag siab zoo dua:
3/ Flow: Ua kom muaj kev vam meej
"Flow" yog npaj los tsim kom muaj kev sib luag thiab txuas ntxiv ntawm kev ua haujlwm hauv lub koom haum. Lub tswv yim ntawm Flow hais txog tias kev ua haujlwm yuav tsum txav los ntawm ib theem mus rau lwm qhov yam tsis muaj kev cuam tshuam lossis cuam tshuam, thaum kawg txhawb kev ua haujlwm.
Los ntawm kev pom ntawm lub koom haum, Lean txhawb kom tsim kom muaj chaw ua haujlwm uas cov dej num thiab cov dej num ua mus yam tsis muaj kev cuam tshuam lossis qeeb.
Xav txog kev tsim khoom sib dhos ua ib qho piv txwv ntawm kev ua tiav "khiav." Txhua qhov chaw nres tsheb ua haujlwm tshwj xeeb thiab cov khoom txav seamlessly ntawm ib lub chaw nres tsheb mus rau lwm qhov yam tsis muaj kev cuam tshuam. Qhov no qhia txog lub tswvyim ntawm Flow in Lean.
4/ Pull System: Teb rau kev thov
Pull System yog hais txog kev tsim lossis xa cov kev pabcuam hauv kev teb rau cov neeg siv khoom xaj. Cov koom haum siv lub Pull System tsis tsim cov khoom raws li kev xav ntawm kev xav tau yav tom ntej. Hloov chaw, lawv teb rau qhov kev txiav txim tiag tiag tau txais. Qhov kev xyaum no minimizes overproduction, ib qho ntawm xya yam loj ntawm pov tseg hauv Lean manufacturing.
- Ib qho piv txwv ntawm kev rub tawm yog lub khw muag khoom loj. Cov neeg siv khoom rub cov khoom uas lawv xav tau los ntawm cov txee, thiab lub khw muag khoom khaws cov txee raws li xav tau. Cov txheej txheem no ua kom ntseeg tau tias ib txwm muaj cov khoom muag txaus kom tau raws li cov neeg siv khoom xav tau, tab sis kuj tsis muaj ntau tshaj.
- Lwm qhov piv txwv ntawm kev rub lub kaw lus yog lub tsheb muag khoom. Cov neeg siv khoom rub lub tsheb uas lawv nyiam tawm ntawm ntau thiab coj lawv mus rau kev sim tsav. Lub khw muag khoom tsuas yog xaj cov tsheb tshiab los ntawm cov chaw tsim khoom raws li xav tau kom tau raws li cov neeg siv khoom xav tau.
5/ Kev Txhim Kho Ntxiv (Kaizen)
Lub hauv paus ntsiab lus thib tsib thiab kawg Lean yog "Kev txhim kho txuas ntxiv," hu ua "Kaizen" lossis Kaizen kev txhim kho txuas ntxiv. Nws yog hais txog kev txhawb nqa kev coj noj coj ua ntawm kev txhim kho tsis tu ncua.
Nws koom nrog kev txhim kho me me, zoo ib yam nyob rau lub sijhawm es tsis yog hloov pauv hloov pauv loj. Cov kev txhim kho me me no ntxiv, ua rau muaj kev nce qib tseem ceeb hauv cov txheej txheem, kev ua tau zoo, thiab kev ua haujlwm tag nrho.
Ib qho tseem ceeb ntawm Kaizen yog nws cov xwm txheej. Nws txhawb kom muaj kev koom tes los ntawm txhua theem ntawm lub koom haum, tso cai rau cov neeg ua haujlwm los pab txhawb lawv cov tswv yim, kev soj ntsuam, thiab kev pom. Txoj hauv kev no tsis yog tsuas yog txhim kho cov peev txheej daws teeb meem xwb tab sis kuj ua rau cov neeg ua haujlwm coj ncaj ncees thiab koom nrog.
Kaizen xyuas kom meej tias lub koom haum muaj kev txhawb zog tsis tu ncua kom ua tau zoo dua, ua tau zoo dua, thiab ua tau zoo dua. Nws yog kev cog lus rau kev txhim kho txuas ntxiv thiab yog ib qho tseem ceeb ntawm Lean kab lis kev cai.
kawg
Lub 5 lub hauv paus ntsiab lus ntawm ntshiv tsim: Tus nqi, tus nqi kwj deg, thiab kev txhim kho, thiab kev txhim kho nrog lub moj khaum muaj zog rau kev ua haujlwm zoo tshaj plaws.
Cov koom haum uas tuav L5 Txoj Cai Ntawm Lean Manufacturing tsis tsuas yog txhim kho lawv cov kev ua tau zoo tab sis kuj txo cov pov tseg thiab txhim kho lawv cov khoom thiab cov kev pabcuam zoo.
