Rau kev rov qab mus, ua raws cov kauj ruam no:

  1. 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.
  2. Tshem tawm lub sijhawm thiab ntxiv 1 los tsim qhov pib lig rau cov haujlwm kawg hauv qhov qhov project .

Ntawm no, koj yuav suav li cas rau pem hauv ntej thiab rov qab hla hauv qhov project tswj?

Forward pass yog ib txoj kev txav mus los rau pem hauv ntej los ntawm network daim duab mus rau kev 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 rau xam pib lig los yog nrhiav seb puas muaj kev poob qis hauv qhov kev ua si.

Tsis tas li ntawd, 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.

Yog li ntawd, dab tsi qhov tseem ceeb yog xam nyob rau hauv rov qab pass ntawm ib 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

Dab tsi yog qhov rov qab hla hauv kev tswj xyuas qhov project?

A rov qab hla dhau hauv thaj tsam ntawm kev tswj 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. Qhov no yog txiav txim los ntawm pib ntawm lub qhov project teem hnub kawg thiab ua haujlwm rov qab los ntawm lub sij hawm network logic.
