Hauv kev tsim khoom, nrawm rau kev lag luam thiab cov nqi tsim khoom tuaj yeem ua lossis tawg lub tuam txhab. Tsuas yog nyob rau lub sijhawm (JIT) kev tsim khoom yog ib txoj haujlwm ua haujlwm txhawm rau txo lub sijhawm ntws hauv cov tshuab tsim khoom, nrog rau lub sijhawm teb los ntawm cov neeg muag khoom thiab rau cov neeg siv khoom.
Yuav ua li cas yog lub sijhawm hauv kev tsim khoom?
Lean manufacturing (tseem hu ua lean production, just-in-time manufacturing and just-in-time production, or JIT) yog ib txoj kev tsim khoom siv feem ntau ntawm kev txo lub sijhawm nyob rau hauv cov txheej txheem ntau lawm nrog rau lub sijhawm teb los ntawm cov neeg muag khoom thiab rau cov neeg siv khoom.
Lub sijhawm tsim khoom ua haujlwm li cas?
Just-in-time (JIT) kev tsim khoom hais txog cov kev txhawj xeeb no. Nws yoglub hom phiaj uas txo cov sij hawm cov khoom siv los ntawm kev tsim khoom thiab, tib lub sijhawm, txiav rov qab lub sij hawm teb los ntawm cov neeg muag khoom Tswj cov kev hloov pauv yog tus yuam sij los tuav cov nqi tsim khoom thaum nce productivity.
Qhov laj thawj tseem ceeb ntawm lub sijhawm tsim khoom yog dab tsi?
Dab tsi yog Just-in-Time (JIT)? Just-in-time, lossis JIT, yog ib txoj hauv kev tswj cov khoom muag uas tau txais los ntawm cov neeg muag khoom tsuas yog raws li lawv xav tau. Lub hom phiaj tseem ceeb ntawm txoj kev no yog txo qis cov nqi tuav cov khoom muag thiab nce cov khoom xa tuaj.
Yuav ua li cas yog lub sijhawm xwb?
Just-in-time tseem hu ua JIT yog ib txoj kev tswj cov khoom muag uas yog kev ua haujlwm, cov khoom siv thiab cov khoom (yuav tsum tau siv hauv kev tsim khoom) rov ua dua lossis teem sijhawm kom txog raws nraim thaum xav tau hauvtxheej txheem tsim khoom.
