Nyob rau hauv tsab xov xwm no koj yuav kawm txog cov nqi, cov qauv nqi, thiab tseem nkag siab lub ntsiab lus ntawm lawv qhov kev faib ua ntau hom.

Cov nqi yog cov peev txheej nyiaj txiag uas yuav tsum tau siv los ua cov haujlwm ua lag luam. Kev txheeb xyuas cov nqi (cov qauv nqi tau muab hauv qab no), ib tus tuaj yeem txiav txim siab txog kev ua haujlwm ntawm kev tswj hwm ntawm nws cov peev txheej.

Cov nqi tsim khoom zoo li no tau muab faib ua ntau hom, nyob ntawm seb lawv cuam tshuam li cas los ntawm kev hloov pauv ntawm cov ntim ntau lawm.

Ntxhais

Raws li cov nqi tas li lawv txhais tau tias cov nqi no, tus nqi uas tsis cuam tshuam los ntawm qhov ntim ntawm kev tsim khoom. Ntawd yog, lawv cov nqi yuav zoo ib yam li thaum lub tuam txhab ua haujlwm hauv kev txhim kho, siv tag nrho cov peev txheej, lossis, hloov pauv, thaum lub sijhawm tsim khoom.

Piv txwv li, cov nqi no tuaj yeem yog tus thawj coj lossis qee yam khoom sib cais los ntawm tus nqi ntawm cov nqi tsim khoom dav dav (cov nqi xauj tsev, cov nuj nqis rau kev saib xyuas engineering thiab cov neeg ua haujlwm tsis muaj feem cuam tshuam nrog cov txheej txheem tsim khoom), cov nyiaj hli cov neeg ua haujlwm, txiav tawm rau nyiaj tuav pov hwm, nqi ntawv tso cai,software thiab lwm yam.

Nws tsim nyog sau cia tias qhov tseeb cov nqi no tsis tuaj yeem hu ua tas li. Tseem, qhov ntim ntawm ntau lawm tuaj yeem cuam tshuam rau lawv, txawm tias tsis ncaj qha, tab sis tsis ncaj. Piv txwv li, kev nce ntim ntawm cov khoom tsim tawm tuaj yeem xav tau qhov chaw dawb hauv cov tsev khaws khoom, ntxiv kev saib xyuas cov txheej txheem uas hnav sai dua.

Ntau zaus hauv cov ntaub ntawv, cov kws tshawb fawb siv nyiaj txiag feem ntau siv lo lus "cov nqi kho mob tas li ntawm kev tsim khoom."

Variables

Tsis zoo li cov nqi tas li, cov nqi sib txawv yog ncaj qha proportional rau ntim ntawm cov khoom tsim.

Hom no suav nrog cov khoom siv raw, cov khoom siv, lwm yam khoom siv uas koom nrog hauv cov txheej txheem tsim khoom, hluav taws xob thiab ntau hom nqi. Piv txwv li, thaum tsim cov thawv ntoo los ntawm 100 units, nws yog ib qho tsim nyog yuav tau yuav cov khoom siv uas lawv yuav raug tsim.

Tus nqi tib yam tuaj yeem sib txawv

Ntxiv mus, cov nqi tib yam tuaj yeem yog ntau hom, thiab, raws li, cov nqi sib txawv. Tus nqi qauv los ntawm cov nqi no tuaj yeem suav tau tseeb tseeb qhov tseeb.

Piv txwv li, hluav taws xob. Lub teeb teeb, cua txias, kiv cua, khoos phis tawj - tag nrho cov cuab yeej no uas tau teeb tsa hauv chaw ua haujlwm yog siv hluav taws xob. Cov cuab yeej siv tshuab, cov cuab yeej siv tshuab thiab lwm yam khoom siv uas koom nrog hauv kev tsim khoom, cov khoom lag luam, thiabsiv hluav taws xob.

Tib lub sijhawm, hauv kev txheeb xyuas nyiaj txiag, hluav taws xob tau sib cais kom meej thiab hais txog ntau hom nqi. Vim hais tias txhawm rau ua kom raug kev kwv yees ntawm cov nqi yav tom ntej, nrog rau kev suav nyiaj rau cov nqi tam sim no, kev sib cais meej ntawm cov txheej txheem nyob ntawm qhov kev siv ntau lawm yog qhov tsim nyog.

tag nrho cov nqi tsim khoom

Cov nqi sib txawv thiab cov nqi tas li hu ua "tag nrho cov nqi". Cov mis laij lej yog raws li nram no:

Io=Ip + Iper, qhov twg:

IO - tag nrho cov nqi;

F - tus nqi tas;

Iper – tus nqi sib txawv.

qhov ntsuas no txiav txim siab tag nrho cov nqi. Nws txoj kev tsom xam nyob rau hauv dynamics tso cai rau koj pom cov txheej txheem ntawm optimization, restructuring, txo los yog nce nyob rau hauv lub ntim ntawm ntau lawm thiab kev tswj cov txheej txheem ntawm lub enterprise.

Tus nqi tsim khoom nruab nrab

Los ntawm kev faib tag nrho cov nqi ntawm ib chav tsev ntawm cov zis, koj tuaj yeem pom tus nqi nruab nrab. Cov mis laij lej yog raws li nram no:

Is=Io / Op, qhov twg:

Yog - tus nqi nruab nrab;

Op - qhov ntim ntawm kev tsim khoom.

qhov ntsuas no tseem hu ua "tus nqi tag nrho ntawm ib chav tsev ntawm cov khoom tsim tawm." Siv qhov ntsuas no hauv kev txheeb xyuas nyiaj txiag, ib tus tuaj yeem nkag siab tias lub tuam txhab siv nws cov peev txheej los tsim cov khoom lag luam zoo li cas. Tsis zoo li tag nrho cov nqi, cov nqi nruab nrab, cov qauv kev suav uas tau muab los saum toj no, qhia qhov ua tau zoo ntawm cov nyiaj txiag los ntawm 1unit ntawm cov zis.

txhawm rau txheeb xyuas qhov ua tau ntawm kev hloov pauv qhov ntau ntawm cov khoom tsim tawm, qhov taw qhia yog siv uas qhia txog tus nqi ntawm kev tsim khoom rau ib chav tsev ntxiv. Nws hu ua marginal cost. Cov mis laij lej yog raws li nram no:

Ypres=(Io2 - Io1) / (Op2 - Op1), qhov twg:

Ypres – marginal cost.

Qhov kev suav no yuav muaj txiaj ntsig zoo yog tias cov neeg ua haujlwm tswj hwm ntawm lub tuam txhab txiav txim siab nce cov ntim ntau lawm, nthuav dav thiab ua lwm yam kev hloov pauv hauv cov txheej txheem ntau lawm.

Yog li, tom qab koj tau kawm txog cov nqi, cov qauv nqi, nws paub meej tias yog vim li cas kev lag luam tsom xam kom meej meej cais cov nqi ntawm cov khoom loj, kev tswj hwm thiab kev tswj hwm, nrog rau cov nqi tsim khoom dav dav.
