Forward pass yog ib txoj kev txav mus los rau pem hauv ntej los ntawm lub network daim duab los txiav txim qhov project ncua sij hawm thiab nrhiav txoj hauv kev tseem ceeb lossis Free Float ntawm qhov project . Qhov twg rov qab hla dhau sawv cev mus rov qab mus rau qhov kawg tshwm sim los xam qhov pib lig lossis nrhiav seb puas muaj kev poob qis hauv qhov kev ua si.
Dhau li ntawm no, dab tsi yog backward pass?
A rov qab hla dhau nyob rau hauv thaj tsam ntawm kev tswj xyuas qhov project yog hais txog kev suav cov hnub ua tiav lig thiab hnub pib lig rau feem ntawm cov sijhawm ua haujlwm uas tsis tau ua tiav.
Ib sab saum toj no, PERT daim duab yog dab tsi? A PERT daim ntawv qhia yog qhov cuab yeej tswj hwm qhov haujlwm uas muab cov duab sawv cev ntawm qhov haujlwm raws sijhawm. Txoj Haujlwm Kev Ntsuam Xyuas Kev Ntsuam Xyuas ( PERT ) rhuav tshem cov haujlwm ntawm tus kheej ntawm ib qhov project rau kev txheeb xyuas.
Ntxiv rau qhov no, cov txiaj ntsig dab tsi suav nrog ntawm qhov rov qab dhau ntawm qhov project network?
Los ntawm qhov no dhau , Lub Caij Nplooj Ntoos Hlav thiab Caij Nplooj Ntoos Hlav cov nqi raug xam . Cov qauv rau cov rov qab hla dhau yog qhia hauv qab no: Late Start = LF - Duration. Late Finish = Yam tsawg kawg nkaus (lossis qis tshaj) LS tus nqi los ntawm cov neeg ua tiav tam sim
Koj ua li cas rov qab hla dhau?
Rau kev rov qab mus, ua raws cov kauj ruam no:
- Siv lub sijhawm ua tiav thaum ntxov ntawm cov haujlwm kawg hauv lub network thiab sau tus lej ntawd raws li hnub ua tiav lig thiab.
- Tshem tawm lub sijhawm thiab ntxiv 1 txhawm rau tsim qhov pib lig rau cov haujlwm kawg hauv qhov project.

Kev xaiv qhov project hauv kev tswj qhov project yog dab tsi?
Kev xaiv qhov project yog txheej txheem los ntsuas txhua lub tswv yim ntawm qhov project thiab xaiv qhov project nrog qhov tseem ceeb tshaj plaws. Cov phiaj xwm tseem tsuas yog cov lus qhia nyob rau theem no, yog li kev xaiv feem ntau ua raws li cov lus piav qhia luv luv ntawm qhov project. Cov txiaj ntsig: Kev ntsuas ntawm qhov txiaj ntsig zoo ntawm txoj haujlwm
Dab tsi yog qhov project thiab dab tsi tsis yog qhov project?
Qhov tseem ceeb yog dab tsi tsis yog qhov project yog cov txheej txheem txuas ntxiv, kev lag luam raws li ib txwm ua haujlwm, tsim khoom, txhais pib thiab xaus hnub, tsis muaj teeb meem yog tias nws hnub lossis xyoo, tab sis nws yuav tsum ua tiav hauv lub sijhawm kom xa tag nrho. pab neeg ua haujlwm ntawm qhov project
Qhov project thiab qhov project lifecycle yog dab tsi?
Lub voj voog ntawm lub neej yog qhov sib lawv liag ntawm cov theem uas ib qhov project mus dhau los ntawm nws qhov pib mus rau nws kaw. Qhov project lifecycle tuaj yeem txhais tau thiab hloov kho raws li qhov xav tau thiab yam ntawm lub koom haum
Dab tsi yog qhov tseem ceeb ntawm EOQ hauv kev tswj cov khoom muag thiab hauv kev tswj xyuas kev ua haujlwm feem ntau?
EOQ xam qhov kev txiav txim kom muaj nuj nqis rau cov khoom lag luam tshwj xeeb uas siv cov khoom siv xws li nqa tus nqi, tus nqi xaj, thiab kev siv txhua xyoo ntawm cov khoom muag khoom. Kev Tswj Nyiaj Txiag Ua Haujlwm yog qhov tseem ceeb tshwj xeeb ntawm kev tswj nyiaj txiag
Tshooj 404 xav tau dab tsi ntawm kev tswj hwm cov ntaub ntawv tswj xyuas sab hauv tshawb fawb lub tuam txhab pej xeem thiab piav qhia txog kev tswj hwm cov ntaub ntawv ntawm kev tswj hwm sab hauv kom ua tau raws li cov cai ntawm ntu 40
Txoj Cai Sarbanes-Oxley xav kom cov kev tswj hwm ntawm cov tuam txhab pej xeem ntsuas qhov ua tau zoo ntawm kev tswj hwm sab hauv ntawm cov neeg tawm tswv yim rau kev tshaj tawm nyiaj txiag. Tshooj 404(b) xav kom ib lub tuam txhab tuav pov hwm tus neeg soj ntsuam los ua pov thawj rau, thiab tshaj tawm txog, kev tswj xyuas kev ntsuam xyuas ntawm nws cov kev tswj hwm sab hauv
