Kev tswj kom zoo ( QC ) yog cov txheej txheem lossis txheej txheej txheej txheem tsim los xyuas kom meej tias cov khoom tsim los yog kev pabcuam ua raws li cov txheej txheem kev ua tau zoo lossis ua tau raws li qhov xav tau ntawm cov neeg siv khoom lossis cov neeg siv khoom. QC zoo ib yam li, tab sis tsis zoo ib yam nrog, kev ruaj ntseg zoo (QA).
Ntawm no, tus qauv tswj kev ua tau zoo yog dab tsi?
Cov qauv zoo txhais tau tias yog cov ntaub ntawv uas muab cov kev xav tau, kev qhia tshwj xeeb, cov lus qhia, lossis cov yam ntxwv uas tuaj yeem siv tsis tu ncua los xyuas kom meej tias cov khoom siv, cov khoom, cov txheej txheem, thiab cov kev pabcuam haum rau lawv lub hom phiaj.
Ib yam li ntawd, QC daim ntawv txheeb xyuas yog dab tsi? Kev tswj kom zoo daim ntawv teev npe yog ib qho kev qhia ntawv rau koj cov khoom 'cov ntsiab lus, ntim, xim, barcodes, tsos, muaj peev xwm tsis xws luag, kev ua haujlwm thiab cov kev cai tshwj xeeb. Nws kuj yog qee zaum hu ua "cov ntawv tshuaj ntsuam xyuas" lossis kev tshuaj xyuas daim ntawv teev npe.
Ib yam li ntawd, koj tuaj yeem nug, 4 hom kev tswj xyuas zoo yog dab tsi?
Muaj xya yam kev tswj xyuas qhov zoo uas suav nrog:
- Txheeb xyuas Ntawm nws qhov yooj yim tshaj plaws, kev tswj xyuas kom zoo yuav tsum tau kuaj xyuas cov npe ntawm cov khoom uas yuav tsum tau ua thiab muag koj cov khoom.
- Daim duab Fishbone.
- Tswj daim duab.
- Stratification.
- Pareto daim ntawv qhia.
- Histogram.
- Scatter Diagram.
Dab tsi yog qhov txawv ntawm QA & QC?
Cov qhov sib txawv ntawm kev ruaj ntseg zoo thiab kev tswj kom zoo yog tias Kev Tswj Xyuas Zoo yog cov khoom taw qhia, thaum Quality Assurance yog txheej txheem taw qhia. Thaum QC xyuas kom cov txiaj ntsig ntawm qhov koj tau ua yog raws li koj qhov kev cia siab. Ob leeg QC thiab QA yog interdependent rau ib leeg.

Tus qauv Ramsey txawv ntawm tus qauv Solow li cas?
Tus qauv Ramsey-Cass-Koopmans txawv ntawm Solow-Swan qauv nyob rau hauv qhov kev xaiv ntawm kev noj yog qhia meej meej microfounded ntawm ib tug taw tes nyob rau hauv lub sij hawm thiab yog li endogenizes tus nqi txuag. Yog li ntawd, tsis zoo li nyob rau hauv tus qauv Solow-Swan, qhov kev txuag tus nqi yuav tsis tas mus li ntawm kev hloov mus rau lub sijhawm ntev
Dab tsi yog qhov txawv ntawm tus qauv dej tsaws tsag thiab cov qauv rov ua dua?
Tus qauv dej tsaws tsag ntshiab zoo li dej tsaws tsag uas txhua kauj ruam yog theem sib txawv. Cov kev hloov pauv hauv cov txheej txheem dej tsaws tsag yuav ua raws li Txoj Cai Tswjfwm Hloov Hloov uas tswj los ntawm Pawg Tswjhwm Hloov Hloov. Iterative qauv yog ib qho uas muaj ntau tshaj 1 repetition ntawm theem ntawm kev ua ub no nyob rau hauv ib tug txheej txheem
Dab tsi yog tus qauv rau tus nqi sib tw elasticity?
Hla elasticity (Exy) qhia peb txog kev sib raug zoo ntawm ob yam khoom. nws ntsuas qhov rhiab heev ntawm qhov xav tau hloov pauv ntawm cov khoom X mus rau qhov hloov pauv ntawm tus nqi ntawm cov khoom Y. Nqe elasticity mis: Exy = feem pua hloov hauv Quantity xav tau ntawm X / feem pua ntawm cov nqi ntawm Y
Tus qauv ntawm tus nqi zog rau ib chav tsev yog dab tsi?
Txhawm rau xam tus lej, muab cov lej ua haujlwm ncaj qha ib teev los ntawm cov sijhawm ua haujlwm ncaj qha uas yuav tsum tau ua kom tiav ib chav. Piv txwv li, yog tias tus nqi ua haujlwm ncaj qha ib teev yog $ 10 thiab nws yuav siv sijhawm tsib teev los ua kom tiav ib chav, tus nqi ua haujlwm ncaj qha rau ib chav yog $ 10 muab rau tsib teev, lossis $ 50
Dab tsi yog qhov txawv ntawm tus qauv tsim nqi ncaj ncees thiab tus qauv rov ntsuas dua?
Lwm yam tshaj tus nqi ncaj ncees tsis muaj depreciation whereas revaluation qauv muaj depreciation. Yog tias muaj qhov nce hauv tus qauv tus nqi ncaj ncees rau cov cuab yeej nqis peev, puas yog qhov txiaj ntsig tseem hu ua qhov nce ntawm kev txheeb xyuas uas yog tib yam rau tus qauv rov qab rau ppe???
