Kev Tswj Xyuas Zoo (QC) yog tus txheej txheem los xyuas kom meej tias cov zoo ntawm ib yam khoom los yog kev pab cuam tau ua tau raws li tej yam kev cai predetermined. Vim tias nws yuav siv qhov chaw tom qab ib qho khoom tsim tawm nws feem ntau koom nrog cov haujlwm xws li kev tshuaj xyuas los yog kuaj.

Ib yam li ntawd, lub luag haujlwm ntawm kev tshuaj xyuas hauv kev tswj kom zoo yog dab tsi?

Kev tshuaj xyuas suav nrog ntsuas, tshuaj xyuas thiab ntsuas cov khoom, txheej txheem thiab cov kev pabcuam tiv thaiv cov cai tshwj xeeb los txiav txim siab ua raws. Ib kev tshuaj xyuas txiav txim siab seb cov khoom lossis cov khoom puas nyob rau hauv kom muaj nuj nqis thiab mob. Hauv kev tswj kom zoo , cov lub luag haujlwm ntawm kev tshuaj xyuas yog los xyuas thiab validate cov ntaub ntawv variance.

Tsis tas li ntawd, 4 hom kev tswj kom 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.

Yog li ntawd, qhov txawv ntawm kev tswj xyuas zoo thiab kev tshuaj xyuas yog dab tsi?

Kev tswj kom zoo hais dav dav rau cov txheej txheem ntawm kev tswj cov khoom zoo kom tau raws li tus qauv xav tau. Kev tshuaj xyuas tsuas yog ib feem ntawm cov txheej txheem no siv los txheeb xyuas zoo cov khoom tsis raug.

Kev tswj kom zoo thiab nws txoj haujlwm yog dab tsi?

Lub ntsiab muaj nuj nqi ntawm kev tswj kom zoo yog kuaj thiab xyuas cov khoom zoo tawm tsam cov txheej txheem ua ntej. Kev Tswj Xyuas Zoo chav haujlwm muaj nuj nqi rau kom paub tseeb tias zoo ntawm tag nrho cov khoom tsim, nyob rau txhua theem ntawm kev tsim khoom / ua cov Khoom Siv Tshuaj.
