Kev kwv yees kev nqis peev yog qhov tsim nyog vim kev nce nqi thiab kev hloov pauv nqi muaj kev paub los ntawm tuam txhab . Yog tias koj ua raws li $ 110 nqi nrog kev muag khoom, lub tuam txhab cov khoom lag luam yuav muaj qis dua nqi . Qhov hnyav-nruab nrab kos yuav txhais tau tias ob qho khoom muag thiab nqi ntawm cov khoom muag yuav raug nqi ntawm $ 105 toj ib chav.

Tib neeg tseem nug, dab tsi yog cov nqi khiav kev xav?

Lub sij hawm tus nqi ntws assumption hais txog yam uas nqi raug tshem tawm ntawm lub tuam txhab cov khoom lag luam thiab tau tshaj tawm raws li nqi ntawm cov khoom muag. Hauv Tebchaws Meskas kev kwv yees kev nqis peev suav nrog FIFO, LIFO, thiab nruab nrab. (Yog tias siv cov cim tshwj xeeb, tsis tas yuav tsum ua ib qho kev xav .)

Tsis tas li, qhov kev kwv yees tus nqi zoo li tau siv los ntawm ntau lub tuam txhab ntau dua li lwm qhov? FIFO 10. Qhov zoo ntawm kev siv LIFO yog dab tsi? Cov tuam txhab nyiam siv LIFO rau lub hom phiaj ua se vim qhov no kev xav txo cov nyiaj tau los tshaj tawm thiab, yog li, xav tau nyiaj ntsuab kev them nyiaj rau tus tsoom fwv.

Ib sab saum toj no, dab tsi yog FIFO tus nqi khiav kev xav?

Nws yog unrealistic xav tias cov nqi khoom muag yuav nyob tas li nyob rau lub sijhawm vim tias kev ua lag luam hloov pauv tas li ua rau tus nqi ntawm cov khoom hloov pauv raws li kev lag luam hloov pauv. Nqi flow assumption yog li cas ib lub tuam txhab txav cov khoom los ntawm nws cov khoom muag rau nws nqi ntawm cov khoom muag.
