Los ntawm Kerri Simon. 2 lus. Txheej txheem stability yog ib lub ntsiab lus tseem ceeb tshaj plaws ntawm cov Six Sigma methodology, lossis ib qho kev txhim kho zoo rau qhov teeb meem ntawd. Kev ruaj ntseg suav nrog kev ua tiav zoo ib yam thiab, thaum kawg, siab dua txheej txheem yields los ntawm kev siv cov txheej txheem kev txhim kho.

Tsuas yog li ntawd, koj yuav txiav txim siab li cas yog tias tus txheej txheem ruaj khov?

Yog tus txheej txheem Kev faib tawm tseem nyob ib puag ncig lub sijhawm, piv txwv li cov khoom tawm poob hauv qhov ntau ( Txheej txheem Dav), ces tus txheej txheem yog hais tias ruaj khov los yog tswj. Yog cov Outputs yog kis thoob plaws sab nraum qhov txwv, ces tus txheej txheem Tsis ruaj tsis khov los yog Tawm ntawm Kev Tswj.

Qhov thib ob, kev ruaj ntseg hauv kev tswj xyuas yog dab tsi? Txheej Txheem Stability hais txog qhov sib xws ntawm cov txheej txheem nrog rau qhov tseem ceeb txheej txheem cov yam ntxwv xws li tus nqi nruab nrab ntawm qhov tseem ceeb ntawm qhov loj lossis qhov hloov pauv ntawm qhov tseem ceeb ntawd. Yog tias txheej txheem coj tus cwj pwm tsis tu ncua dhau sijhawm, ces peb hais tias tus txheej txheem yog ruaj khov los yog hauv tswj.

Tsis tas li ntawd, dab tsi yog qhov ruaj khov thiab muaj peev xwm txheej txheem?

A Muaj peev xwm txheej txheem yog a txheej txheem uas tau ua tiav nws cov lus qhia zoo thiab cov khoom lag luam thiab cov hom phiaj. A Cov txheej txheem ruaj khov yog ib qho uas ua haujlwm nyob rau hauv cov cai tswj kev txwv thiab tsis muaj kev hloov pauv ntau dhau.

Cov txheej txheem muaj peev xwm yog dab tsi?

Txheej txheem Peev Xwm (Cp) yog qhov ntsuas ntsuas ntawm a txheej txheem muaj peev xwm tsim cov khoom nyob rau hauv cov kev txwv tshwj xeeb raws li qhov sib xws. Cp qhia koj yog koj li txheej txheem yog muaj peev xwm ntawm kev ua cov khoom nyob rau hauv specifications thiab Cpk qhia koj yog tias koj txheej txheem yog nyob nruab nrab ntawm cov kev txwv tshwj xeeb.
