LUB Txoj kev ntawm kaum Teeb tsa qhov ua tau (thaj chaw), S. Nrhiav tus EXACT coordinates ntawm tag nrho cov vertices ( ces kaum cov ntsiab lus) ntawm S. Ntsuas lub hom phiaj muaj nuj nqi, P, ntawm txhua qhov vertex Qhov siab tshaj plaws (yog tias muaj) yog tus nqi loj tshaj plaws ntawm P ntawm vertex. Qhov tsawg kawg nkaus yog qhov tsawg tshaj plaws tus nqi ntawm P ntawm vertex.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog txoj hauv kev los daws LPP?

Graphical Method ntawm kev daws teeb meem Linear Programming

  • Cov yeeb yaj kiab pom zoo.
  • Kauj Ruam 1: Tsim cov LP (Linear programming) teeb meem.
  • Kauj Ruam 2: Tsim ib daim duab thiab npaj cov kab txwv.
  • Kauj Ruam 3: Txiav txim siab qhov siv tau ntawm txhua txoj kab txwv.
  • Kauj Ruam 4: Txheeb xyuas thaj tsam kev daws teeb meem ua tau.
  • Kauj Ruam 5: Teeb lub hom phiaj ua haujlwm ntawm daim duab.
  • Kauj ruam 6: Nrhiav qhov zoo tshaj plaws point.

Dab tsi yog txoj hauv kev algebraic hauv linear programming? Algebra thiab Simplex Txoj kev . A linear programming teeb meem (LP) ib teeb meem optimization qhov twg tag nrho cov hloov pauv tsis tu ncua, lub hom phiaj yog a kab tawm (nrog rau qhov kev txiav txim siab sib txawv) muaj nuj nqi, thiab thaj tsam ua tau yog txhais los ntawm tus lej kawg ntawm kab tawm tsis sib npaug los yog sib npaug.

Ntawm no, koj ua li cas xam cov ntsiab lus ntawm cov kab hauv kab?

Cov kaum cov ntsiab lus yog cov vertices ntawm cheeb tsam ua tau. Thaum koj muaj daim duab ntawm qhov system ntawm kab tawm kev tsis sib xws, tom qab ntawd koj tuaj yeem saib daim duab thiab yooj yim qhia qhov twg kaum cov ntsiab lus yog. Tej zaum koj yuav tau daws ib qhov system ntawm kab tawm sib npaug rau nrhiav ib co ntawm cov coordinates ntawm lub cov ntsiab lus nyob nruab nrab.

Txoj kev daws teeb meem ntawm kaum point yog dab tsi?

Cov kaum point daws txoj kev muaj plaub cov kauj ruam tseem ceeb:: Txiav txim siab qhov kev sib koom tes ntawm txhua qhov vertex ( kaum point ) ntawm thaj tsam ua tau.: Xam tus nqi ntawm lub hom phiaj ua haujlwm ntawm txhua kaum point .: Tsim lub hom phiaj ua haujlwm nrog tus nqi siab tshaj plaws.
