Kev sim kuaj

Ntawm txhua yam kev kuaj xyuas txog kev haumxeeb yog txoj cai ua haujlwm, vim tias qhov kev pabcuam yuav tsum ua haujlwm ua ntej txhua yam kom raug, tsis pub siv yooj yim ntawm kev siv, kev ruaj ntseg thiab txaus ceev yuav muaj kev tsis sib nkag siab kiag li. Ntxiv nrog rau cov tswv yim sib tw, txhua tus kws kho mob tshwj xeeb yuav tsum to taub tias yuav ua li cas thiaj li tau txais cov txiaj ntsim zoo tshaj plaws.

Kev sim ua haujlwm: qhov twg yuav tswj tau lub dag zog tseem ceeb?

- kev kuaj thiab kho qhov system;

- Tshawb lub thawv "dawb" lossis "dub";

- kev ntsuam xyuas thiab kev siv hluav taws xob;

- mus sim tshiab nta los yog regression xeem ;

- mus rau "tsis pom zoo" lossis "zoo" cov kev xeem.

Nyob sib txig ntawm cov haujlwm no nws yog ib qho tseem ceeb uas yuav tau nrhiav txoj hau kev, uas yuav yog "qhov nruab nrab", kom sib npaug zog, siv cov lus qhia kom siab tshaj plaws.

Lub software yog xeem ntau txoj hauv kev, ib qho ntawm kev xeem ntawm "black box" los yog kev tswj xyuas cov ntaub ntawv.

Qhov kev zov me nyuam hauv qhov no yog nthuav tawm ntawm qhov kev xam pom ntawm "black box", thiab daim tshev raug coj los xyuas seb qhov kev cuam tshuam ntawm qhov kev zov me nyuam yuav tsis tau raws li qhov kev paub meej. Tag nrho cov uas tsis raug txiav txim los ntawm txoj kev ntawm cov ntaub ntawv los xyuas dua, uas yog nqa tawm los ntawm txoj kev exhaustive xeem, uas yog, siv tag nrho cov tau cov ntaub ntawv hom.

Yog hais tias rau qhov kev pab cuam qhov kev ua tiav ntawm cov lus txib yuav yog nyob ntawm cov txheej xwm ua ntej nws, ces nws yuav tsum txheeb xyuas txhua theem tau ua. Nws yog heev pom tseeb hais tias feem ntau nws tsuas yog tsis yooj yim sua kom ua tiav kev soj ntsuam, yog li ntawd, ib qho kev xaiv lossis kev tsim nyog tau xaiv ntau zaus, xaiv cov kev khiav hauj lwm ntawm ib qho me me ntawm tag nrho cov ntaub ntawv tawm tswv yim. Qhov kev xaiv no tsuas yog ua kom tiav qhov tsis tuaj ntawm kev hloov ntawm cov lus qhia.

Qhov kev kuaj xyuas kev ua haujlwm yuav tsum xaiv txoj kev xeem. Tib lub sij hawm, nws yog txoj kev cai kom paub qhov txawv ntawm cov hau kev ua tus poob rau lawv:

- kev ntsuam xyuas ntawm qhov tseem ceeb ciam;

- qhov muab faib sib npaug;

- xav tias qhov yuam kev;

- kev txheeb ntawm kev sib raug zoo ntawm qhov ua rau thiab qhov tshwm sim.

Koj tuaj yeem xav txog txhua tus nyias muaj nyias.

Kev soj ntsuam ntawm qhov tseem ceeb ntawm tus ciam. Los ntawm cov ciam qhov tseem ceeb nws yog txoj kev cai uas txhais tau hais tias cov neeg nyob hauv thaj tsam ntawm hom kawm sib npaug. Nyob rau hauv xws li qhov chaw, nws yog ntau dua mus ntes ib qho yuam kev. Kev siv txoj kev zoo li no yuav kom tus kws paub hauj lwm tshwj xeeb kom muaj lub tswv yim zoo, nrog rau kev tshwj xeeb hauv qhov teeb meem no.

Qhov muab faib ua ke. Tag nrho cov teeb meem ntawm cov lus tawm tsis tau muab faib ua ob peb yam kev kawm sib npaug. Cov ntaub ntawv raug muab tso ua ke raws li txoj cai ntawm kev ua kom raug zoo ib yam. Nws yog xam tias yog ib txheej ntawm ib chav kawm pom ib qho yuam kev, ces cov khoom sib npaug yuav taw rau nws. Kev soj ntsuam ntawm qhov kev ua tiav no yog ua tiav hauv ob theem: thawj yog kev faib cov kev kawm sib npaug zos, thiab qhov thib ob twb muab cov ntawv xeem tshwj xeeb.

Kev txheeb xyuas ntawm kev sib raug zoo ntawm kev ua thiab kev tshwm sim. Lub kaw lus tuaj yeem xaiv cov kev xeem nrog kev ua tau zoo vim yog cov kev xeem no. Hauv qhov no, yog vim li cas, yuav tsum tau txais ib qho kev tawm tswv yim cais, thiab thaum muaj kev cuam tshuam, pom muaj qhov zis tawm. Tus qauv no yog tsim los ntawm lub tswv yim ntawm kev muab txhua yam ua rau qee yam kev rau txim, uas yog, ntawm qhov kev pom tseeb ntawm cov kev sib raug zoo tshaj. Kev xeem cov khoom software yog nqa tawm hauv ntau theem, ua rau muaj npe ntawm qhov ua rau thiab qhov yuav tshwm.
