Lub hom phiaj tseem ceeb ntawm txhua lub tuam txhab lag luam yog kom tau txais txiaj ntsig ntau tshaj plaws. Qhov no txhais tau tias yuav tsum tau txiav cov nqi. Cov coefficient ntawm kev siv cov ntaub ntawv yog ib qho kev qhia uas tso cai rau koj los soj ntsuam cov rationality ntawm lub tom kawg, lawv xav tau kom tau qhov kawg tshwm sim. Yog tias lub tuam txhab pov tseg ntau cov peev txheej, ces nws tsis tuaj yeem ua tiav. Kev khwv tau nyiaj ntau tshaj yog ua tau nyob rau hauv ib puag ncig kev sib tw tsuas yog txo tus nqi.

Production as a process

Kev txiav txim siab siv tus nqi ntawm cov ntaub ntawv tso cai rau koj los ntsuas seb cov khoom tsim tawm puas muaj txiaj ntsig thiab muaj txiaj ntsig. Tom qab ntawd, yog tias qhov ntsuas tsis txaus siab rau peb, peb yuav tsum sim hloov qhov xwm txheej. Txawm li cas los xij, qhov no tsis yooj yim sua yog tias koj tsis muaj lub tswv yim txog cov txheej txheem tsim khoom. Yog li ntawd, pib nrog, cia peb xav txog nws siv cov piv txwv ntawm kev lag luam engineering. Nws yog qhov yooj yim rau kev txheeb xyuas vimcov txheej txheem tsim khoom ntawm feem ntau cov tuam txhab hauv cheeb tsam no zoo ib yam.

Thawj theem yog kev tsim cov khoom siv raw thiab qhov khoob. Twb tau ntawm no peb tuaj yeem ntsib cov nqi. Ntau cov khoom siv raw khoom siv pov tseg, ntau qhov kev siv cov khoom siv yuav txawv ntawm kev sib koom ua ke. Qhov thib ob theem yog txuam nrog kev ua cov blanks thiab muab lawv cov kev teeb tsa uas yuav tsum tau ua. Lawm, qhov no kuj tuaj nrog cov nqi. Ntxiv mus, lawv nyob ntawm qhov ua tau zoo ntawm qhov pib theem. Nyob rau theem thib peb, kev sib dhos ua ntej thiab ncaj qha ntawm cov khoom yuav tshwm sim.

Indicators of production factor

Cov khoom tsim tau tuaj yeem ua rau ob qho tib si hauv lub cev thiab hauv cov nqe lus muaj nqis. Txhua tus nkag siab tias lub tuam txhab tuaj yeem ua haujlwm txuas ntxiv thaum nws cov nyiaj tau los tshaj nws cov nqi. Txawm li cas los xij, tom kawg yog dab tsi? Xav txog tus qauv peb yam. Txhawm rau tsim cov khoom, peb xav tau cov cuab yeej. Cov no yog peb cov nyiaj tseem ceeb. Lub rationality thiab efficiency ntawm ntau lawm nyob ntawm seb peb siv lawv li cas: intensively los yog dav. Characterizes cov hauj lwm zoo ntawm cov yam tseem ceeb peev productivity. Tus inverse ntawm qhov ntsuas no kuj siv.

Tsis tas li, cov khoom siv zog yog xav tau los tsim cov khoom. Cov no yog peb cov peev txheej ua haujlwm. Qhov ntawd tsuas yog lawv thiab qhia qhov coefficient ntawm kev siv cov ntaub ntawv. Kev ua tau zoo yog qhia los ntawm qhov ntsuas uas twb tau hais hauv qhov kev piav qhia ntawm cov cuab yeej ruaj khov. Qhov no yog material yield. Thaum kawg,lub zog ua haujlwm yog qhov tseem ceeb ntawm kev tsim khoom. Nws tseem tuaj yeem siv dav thiab siv zog. Thiab nws cuam tshuam rau peb cov nqi. Ib qho qhia txog kev ua haujlwm ntawm kev ua haujlwm yog kev tsim khoom ntawm cov neeg ua haujlwm thiab kev siv zog ntawm cov khoom. Cov no kuj yog inverse indicators.

Khoom siv tus nqi

Tus qauv ntawm qhov ntsuas no qhia txog cov peev txheej ua haujlwm. Tsis tas li ntawd, kev siv cov khoom ntawm kev ua haujlwm qhia txog cov khoom tiav ntawm cov khoom tiav. Qhov ntsuas tom kawg feem ntau yog siv rau hauv kev lag luam uas qhov kev ua haujlwm tseem ceeb ntawm cov khoom siv raw yuav siv qhov chaw.

Hauv kev tsim khoom, kev siv cov ntaub ntawv feem ntau suav nrog. Lawv xav txog qhov feem pua ntawm cov khoom siv raw yuav tsum muaj nyob rau hauv cov khoom tiav, thiab txhua yam zoo li qhov tseeb. Muaj ob hom kev siv tus nqi.

Planned

Thawj hom kev ntsuas, raws li lub npe txhais tau, yog kwv yees. Nws yog siv los npaj cov dej num ntxiv thiab tsim kom muaj lub tswv yim txhim kho. Cov mis yog raws li nram no: Kpl \u003d Mch / Mn. Nws siv cov lus pom zoo hauv qab no: Kpl yog qhov kev npaj siv, Mch yog qhov hnyav ntawm cov khoom, Mn yog kev noj cov khoom raws li cov qauv tsim. Raws li tau pom los ntawm cov qauv, nws tsis zoo qhia txog qhov xwm txheej tiag tiag. Cov qauv yog teem rau qhov xwm txheej hypothetical. Qhov tseeb, peb yuav ntsib tus nqi ntau dua li qhov tau npaj tseg.

Qhov tiag

Qhov ntsuas no twb muaj tseeb dua tus yam ntxwv ntawm kev siv cov khoom ntawm kev ua haujlwm. Peb qhia conditionalnpe. Cia Kf yog qhov siv tau tiag tiag, Mch yog qhov hnyav ntawm cov khoom, zoo li hauv rooj plaub dhau los, thiab Mf yog cov khoom siv tiag tiag. Ces tus qauv yuav zoo li no: Kf=Mch / Mf.

Nws yog ib qho yooj yim pom tias nyob rau hauv ob qho tib si tus coefficient tuaj yeem coj qhov tseem ceeb ntawm 0 txog 1. Txawm li cas los xij, qhov tseeb nws tsis tuaj yeem sib npaug rau ib qho. Ib txwm ib feem ntawm cov khoom siv pov tseg, tab sis tsis muaj nyob rau hauv cov khoom tiav. Tab sis nws yog ib qho tseem ceeb kom nkag siab tias ib feem ntawm nws tuaj yeem rov qab siv tau lossis rov ua dua tshiab, uas cov lus nug coefficient tsis suav nrog. Yog li ntawd, cov txheej txheem tsim khoom yuav tsum tau txheeb xyuas kom meej, thiab tsis yog tsom rau tus lej xwb.

Khoom siv tus nqi

Qhov no yog lwm qhov qhia tseem ceeb uas qhia txog cov xwm txheej hauv kev lag luam. Peb nthuav qhia cov ntawv sau tseg. Cia C ua tus nqi noj khoom haus, thiab Kf tus naj npawb ntawm cov khoom tsim tawm tiag tiag. Rau cov qauv, peb kuj xav tau cov khoom siv tiag tiag - Mt. Cia Ned yog tus nqi ntawm kev noj ib chav tsev ntawm cov zis. Ces C \u003d (Mf / KfWeek)100%.

Txoj kev txhim kho kev ua haujlwm

Kev siv cov ntaub ntawv tsim nyog tso cai rau lub tuam txhab kom tau txais txiaj ntsig ntau tshaj plaws. Txawm li cas los xij, ntau nyob ntawm qhov xwm txheej hauv kev lag luam tag nrho.

kev txiav txim siab ntawm kev siv cov khoom siv
kev txiav txim siab ntawm kev siv cov khoom siv

Cov hauv qab no cuam tshuam rau cov khoom siv:

  • Txhim kho thev naus laus zis ntawm cov txheej txheem tsim khoom. Yog lub tuam txhab thiabRaws li kev lag luam txhim kho, dhau sij hawm, txhua tus tau txais kev sib yuav tsawg dua rau ib chav tsev ntawm cov zis. Qhov no txhais tau hais tias cov khoom siv tau siv ntau dua, thiab cov nqi raug txo.
  • Txhim kho cov txheej txheem kev npaj ntawm cov txheej txheem tsim khoom. Qhov no yog hais txog kev txhim kho ib feem tsim, xaiv workpiece thiab xaiv cov khoom siv.
  • Txhim kho lub koom haum ntawm cov txheej txheem tsim khoom. Qhov no tuaj yeem suav nrog kev txhim kho kev koom tes ntawm cov tuam haujlwm, kev sib zog ntawm kev tshwj xeeb, kev txhim kho cov txheej txheem kev npaj.

Example

Xav txog kev txiav chipboard rau kev tsim khoom. Qhov ntau rational yog, cov khoom tsawg dua peb nkim. Kev siv qhov tseem ceeb hauv qhov no yuav yog qhov sib npaug ntawm qhov sib piv ntawm thaj chaw ntawm qhov chaw stamped thiab cov khoom ua haujlwm. Qhov zoo dua qhov txiav ntawm chipboard, qhov ze dua qhov ntsuas no yog rau ib qho. Tab sis nws yuav tsum yog dab tsi?

Peb tsis tuaj yeem hloov thaj tsam ntawm qhov chaw stamped nyob rau hauv txhua txoj kev. Nws qhov ntev yog qhia meej. Txawm li cas los xij, peb tuaj yeem cuam tshuam rau thaj tsam ntawm lub workpiece. Nws yog txiav txim siab los ntawm kev sib npaug ntawm cov kauj ruam ntawm qhov chaw los ntawm qhov ntev ntawm cov sawb. Qhov kev lag luam ntau dua qhov contours ntawm cov blanks yav tom ntej nyob, qhov me dua qhov sib txawv ntawm lawv. Qhov no txhais tau tias tsawg dua cov khoom siv. Yog li, los ntawm tib tus nqi ntawm cov khoom siv raw, lub tuam txhab yuav muaj peev xwm ua tau ntau yam khoom. Tus nqi yuav txo qis thiab cov txiaj ntsig yuav nce ntxiv.
