SPC yog txoj kev ntsuas thiab tswj qhov zoo los ntawm kev saib xyuas kev tsim khoom txheej txheem . Zoo cov ntaub ntawv yog sau nyob rau hauv daim ntawv ntawm cov khoom los yog txheej txheem ntsuas los yog nyeem los ntawm ntau lub tshuab lossis ntsuas ntsuas. Cov ntaub ntawv yog sau thiab siv los ntsuas, saib xyuas thiab tswj ib txheej txheem.

Tsuas yog li ntawd, yog cov txheej txheem hauv kev tswj xyuas kev txheeb cais?

A txheej txheem hais tias nyob rau hauv tswj los yog ruaj khov, yog tias nws nyob hauv statistic tswj . A txheej txheem yog nyob rau hauv statistic tswj thaum tag nrho cov laj thawj tshwj xeeb ntawm kev hloov pauv tau raug tshem tawm thiab tsuas yog ua rau muaj kev hloov pauv tseem nyob. Tswj kab kos yog siv los txiav txim seb a txheej txheem yog nyob rau hauv statistic tswj los tsis.

Tsis tas li ntawd, cov txheej txheem ntawm kev tswj xyuas qhov zoo yog dab tsi? Paub thoob ntiaj teb raws li xya qhov kev tswj hwm zoo (7-QC), lawv yog:

  • Daim duab ua rau thiab cuam tshuam (tseem hu ua Ishikawa daim duab lossis daim duab pob txha)
  • Kos daim ntawv.
  • Tswj daim duab.
  • Histogram.
  • Pareto daim ntawv qhia.
  • Scatter daim duab.
  • Stratification.

Hais txog qhov no, daim ntawv teev cov txheej txheem tswj xyuas yog dab tsi?

Kuj hu ua: Shewhart daim duab , statistical process control chart . Cov daim ntawv tswj yog ib daim duab siv los kawm li cas a txheej txheem hloov raws sijhawm. Cov ntaub ntawv yog npaj raws sijhawm. A daim ntawv tswj ib txwm muaj ib txoj kab nruab nrab rau nruab nrab, ib kab rau sab sauv tswj txwv, thiab kab qis rau qis dua tswj txwv.

Cov txheej txheem kev txheeb cais siv rau dab tsi?

Kev tswj xyuas cov txheej txheem ( SPC ) yog ib txoj kev kev tswj kom zoo uas ua haujlwm txheeb cais txoj kev los saib xyuas thiab tswj ib txheej txheem . Qhov no yuav pab kom paub tseeb tias cov txheej txheem ua hauj lwm zoo, ua ntau specification-conforming khoom nrog tsawg pov tseg (rework los yog seem).
