Linear zvirongwa

Linear zvirongwa ndeimwe matavi inokosha wemasvomhu, iro rinoitwa kudzidza yokungotaura uye methodological nheyo chaidzo mabasa. Bazi iri masvomhu iri zvinowanzoshandiswa achangopfuura makore siyana zveupfumi uye mukugadzirwa, iyo isina rokupedzisira basa iri reDare kwemasvomhu kuronga uye kushandiswa zvoga kukarukureta enyika. Bazi iri sayenzi hwokuzvipira kuna kudzidza Linear Optimization yokutevedzera. Kureva Linear zvirongwa yakatsaurirwa kuna nhamba. Kokutanga ino izwi akanga dzataurwa nokuda T. Koopmans muna 1951. Zvakanyanya Kunaka Panguva Yepamuviri hurongwa mutsetse nechimwe chirongwa kuti kwaita chokuita Zvakanyanya Kunaka Panguva Yepamuviri mutengo pamwero, kureva chinangwa vakatsunga inofungidzirwa.

Linear zvirongwa: nzira

Achibatsirwa ane unyanzvi kuti Linear zvirongwa zvinogona kugadziriswa vazhinji matambudziko extremal dzinoitwa upfumi. Muchiitiko chino, kazhinji kunodiwa kuwana zvakanyanyisa tsika mamwe mashandiro ane shanduka. Sezvo hwaro Linear zvirongwa kunoratidzirwa mhinduro kubva Linear equations zvinogona kuchinjwa kuva equations uye Misiyano. Izvi mhando mapurogiramu kunoratidzwa kwemasvomhu Pfungwa variables, sequences uye kutsunga kwakaita nzira yose kukarukureta uye musoro kuongorora. Izvi zvinoshandawo:

- kana paine kwemasvomhu chokwadi uye quantitative kuomesa pakati vakadzidza zvinhu uye variables;

- kana paine zvakafanana zvinhu kuburikidza Masvomhu pakati kutevedzana;

- kuitwa akadzidza panyaya kwemasvomhu pfungwa pamwe kunzwisisa musimboti wenyika zvakavapo.

Linear zvirongwa zviri maindasitiri kugadzirwa kunoita kuti kuverenga pamusoro Zvakanyanya Kunaka Panguva Yepamuviri chokupika michina zvose, kugadzirwa mitsetse, michina, uyewo Mutongo ouchenjeri kushandisa dziripo zvinhu matambudziko.

Mune zvokurima, kana uchishandisa nzira iyi pakutsvaga nemutengo wakaderera chokupa zvokudya pamwe iripo huwandu chikafu. Izvi anofunga mhando uye zviri zvimwe zvinovaka muviri.

Muna foundry indasitiri, unyanzvi ichi kunoita kuti kuwana mhinduro kuna chokufambisa dambudziko uye dambudziko wemisanganiswa, tiri chikamu metallurgia vebasa. Musimboti wacho chokufambisa dambudziko iri iyi hunosanganisira Zvakanyanya Kunaka Panguva Yepamuviri kunoita unoparadza emakambani kuti mabhizimisi kuti vari mubasa kugadzirwa zvinhu.

Linear zvirongwa: dambudziko

A pachena kuchiitwa matambudziko ose zvoupfumi ayo kugadziriswa nzira Linear zvirongwa ndiyo kusarudzwa zvimwe dzakasiyana rokusarudza, uyewo constraints. Nemhaka yokugadzirisa chinetso ichi kuwana zvakanaka mhinduro dzose zvinotsiva.

A guru kukosha kushandisa Linear zvirongwa mitoo ari upfumi ndiye anosarudza kuti Zvakanyanya Kunaka Panguva Yepamuviri musiyano pakati vakawanda zvokusarudza kuti inokurukurwa bvumidzwa zvinobvira. matambudziko akadaro anenge zvisingaiti kugadzirisa mune dzimwe nzira, saka rekukwazisa vanobvumira here kuwana dhigirii ari ouchenjeri kushandisa zvibereko mari. Achibatsirwa Linear zvirongwa anobvumirwa saka huru basa ndiro chokufambisa, izvo zvinofanira kuderedza turnover kuti mutengi nhumbi mukufamba pakukurukura kubva mugadziri.

Mukuita kugadzirisa matambudziko aya atange kusika muenzaniso kuti rinoreva Pfungwa mamiriro ezvinhu mumutauro akarongeka. Pashure danho iri, unogona kuwana mhinduro achishandisa nzira imwe kwakajeka. Pane rinokosha basa "Tsvakai zvinogadzirisa" nokuti izvi Excel.

Sezvo zviri pachena kubva apa, Linear zvirongwa zviri zvikuru kwazvo zvezvinotaurwa chikumbiro.
