Qhov Tseem Ceeb Qhov Sib Txawv - Theem Rov Ua Dua vs Reorder Quantity
Reorder qib thiab rov xaj kom muaj nuj nqis yog ob feem ntau siv cov ntsiab lus uas tseem ceeb heev hauv kev txiav txim cov khoom siv raw rau kev tsim khoom. Kev txiav txim siab txog qib reorder thiab reorder kom muaj nuj nqis yog qhov tseem ceeb txhawm rau tso cai rau cov khoom lag luam uas qeeb yuav raug nqi. Qhov sib txawv tseem ceeb ntawm qib reorder thiab reorder kom muaj nuj nqis yog qhov reorder theem yog cov khoom muag theem uas ib lub tuam txhab yuav tso ib tug tshiab kev txiav txim rau ib tug Tshuag ntawm raw khoom rau ntau lawm whereas reorder kom muaj nuj nqis yog tus naj npawb ntawm units uas yuav tsum tau muab tso rau hauv qhov kev txiav txim tshiab.. Kev tswj xyuas kev noj qab haus huv kev sib raug zoo nrog cov neeg muag khoom raw khoom yog qhov tseem ceeb kom tau txais cov khoom muag thaum txog qib reorder.
Reorder Level yog dab tsi?
Reorder theem, tseem hu ua 'reorder point,' yog qib khoom muag uas lub tuam txhab yuav tso ib qho kev txiav txim tshiab rau cov khoom siv raw rau kev tsim khoom. Raws li kev xav, nws tau xav tias yuav tsum tsis txhob muaj lub sijhawm sib txawv ntawm kev xaj thiab tau txais cov khoom siv raw. Yog li, lub tuam txhab tuaj yeem xaj cov khoom siv tshiab thaum cov khoom lag luam tam sim no poob mus rau xoom thiab cov neeg muag khoom yuav xa cov ntaub ntawv raw. Txawm li cas los xij, nws yog qhov ua tau yuav luag tsis tuaj yeem thiab raug nqi ntau dhau los ua haujlwm xws li kev yuav khoom zoo meej. Yog li, cov tuam txhab nkag siab txog qhov tseem ceeb ntawm kev tswj hwm qhov tsis txaus (ntau) cov khoom lag luam thiab cov khoom lag luam tshiab yuav raug txiav txim thaum cov khoom muag tam sim no mus txog qib uas tau txiav txim siab.
Yuav ua li cas xam cov qib Reorder?
Reorder qib yog xam raws li, Reorder qib=Qhov nruab nrab siv txhua hnub tus nqi x coj lub sijhawm nyob rau hnub
E.g. DEF Lub Tuam Txhab yog lub tuam txhab tsim khoom uas muaj qhov nruab nrab txhua hnub siv cov khoom siv yog 200 units thiab lub sijhawm ua haujlwm yog 12 hnub. Yog li, Reorder qib=20012=2, 400 units
Thaum cov khoom lag luam qib nce mus txog 2,400 units, qhov kev txiav txim tshiab rau cov khoom siv raw yuav tsum muab tso rau.
Reorder qib ua haujlwm raws li ceeb toom ntawm qhov tshwm sim xws li kev ncua sijhawm hauv kev tsim khoom, vim tias qhov qeeb qeeb tuaj yeem txo qis thiab qhov kev txiav txim tshiab tuaj yeem tso rau lub sijhawm.

(1. Kev ruaj ntseg Tshuag, 2. Safety Tshuag + xav tau thaum lub sij hawm reordering, 3. Inventory-level, 4. Stocastic xav tau thaum reordering)
Reorder Quantity yog dab tsi?
Reorder kom muaj nuj nqis yog tus naj npawb ntawm cov units uas yuav tsum tau suav nrog hauv qhov kev txiav txim tshiab. Qhov no tau txiav txim siab thaum ua tiav qib kev xaj rov qab uas qhov kev txiav txim siab tau txiav txim siab txog pes tsawg ntawm cov khoom muag tshiab yuav tsum tau xaj. Nws yog ib qho tseem ceeb sib npaug li kev txiav txim siab thaum twg yuav tso qhov kev txiav txim tshiab vim yog tias muaj cov khoom siv txaus tsis raug txiav txim nws yuav cuam tshuam rau kev tsim khoom.
Yuav ua li cas xam cov Reorder Quantity?
txhawm rau xam qhov rov xaj kom muaj nuj nqis, 'kev txiav txim nyiaj txiag ntau' yog siv. Ntawm no, cov naj npawb ntawm cov units uas yuav tsum tau txiav txim kom txo qis tag nrho cov nqi khoom muag tuaj txog ntawm, Kev txiav txim siab nyiaj txiag ntau=SQRT (2 × Quantity × Tus nqi ib qho kev txiav txim / Tus nqi nqa ib qho kev txiav txim)
Txuas ntxiv los ntawm qhov piv txwv saum toj no, E.g. DEF Lub Tuam Txhab siv qhov ntau ntawm 15,000 units ntawm raw khoom ib xyoos twg. Nws tus nqi ib qho kev txiav txim yog $ 250 nrog tus nqi nqa ib qho kev txiav txim yog $ 10. Yog li, Economic order quantity=SQRT (2 × 15, 000 × 250 / 10)=866 units
DEF yuav tsum tso 17 xaj (thov ib xyoos ib zaug 15,000 faib los ntawm kev txiav txim loj ntawm 866 units.

Summary – Reorder Level vs Reorder Quantity
Qhov sib txawv ntawm qib reorder thiab reorder kom muaj nuj nqis yog tias thaum reorder theem qhia lub tuam txhab thaum yuav tso ib qho kev txiav txim tshiab rau cov khoom raw, reorder kom muaj nuj nqis qhia qhov loj ntawm qhov kev txiav txim. Cov tuam txhab loj loj uas tsim cov khoom lag luam siv ntau yam khoom, yog li rov xaj qib thiab rov xaj kom muaj nuj nqis yuav tsum tau suav rau txhua yam ntawm cov khoom siv raw thiab xaj yuav tsum muab tso nrog cov neeg xa khoom raws sijhawm.
