Kvalitāte un pārbaude
Mar 21, 2018

Tālāk ir aprakstītas četras kvalitātes izmaksu pamatkategorijas:

1, Profilakse - izmaksas, kas radušās plānojot, ieviešot un saglabājot kvalitātes sistēmu, kas nodrošinās atbilstību kvalitātes prasībām ekonomiskā līmenī. Problēmu novēršanas izmaksu piemērs ir apmācība, izmantojot statistisko procesu kontroli.

2, novērtēšana --- izmaksas, kas radušās, nosakot kvalitātes prasību atbilstības pakāpi. Novērtēšanas izmaksu piemērs ir pārbaude.

3. Iekšēja kļūme - izmaksas, kas radušās, ja produkti, sastāvdaļas un materiāli neatbilst kvalitātes prasībām pirms īpašumtiesību nodošanas klientam. Iekšējās kļūmes izmaksu piemērs ir lūžņi.

4, Ārējā kļūme --- izmaksas, kas radušās, kad produkti pēc kvalitātes īpašumtiesību pārejas neatbilst kvalitātes prasībām. Ārējās kļūmes izmaksu piemērs ir garantijas pretenzijas.

Kaut arī kvalitātes kontroles līmeni lielā mērā nosaka varbūtības teorija un statistiskie aprēķini, ir ļoti svarīgi, lai datu vākšanas procesi, uz kuriem šīs procedūras būtu atkarīgas, būtu piemēroti un precīzi. Vislabākā statistiskā procedūra ir bezvērtīga, ja tiek piegādāti bojāti dati un, tāpat kā apstrādes procesi, pārbaudes datu vākšana pati par sevi ir process ar praktiskiem precizitātes, precizitātes, izšķirtspējas un atkārtojamības ierobežojumiem.

Visus pārbaudes un / vai mērīšanas procesus var definēt, ņemot vērā to precizitāti un atkārtojamību, tāpat kā ražošanas procesu novērtē pēc precizitātes un atkārtojamības. Kontrolētos eksperimentus var veikt, un rezultātu statistiskos mērījumus var veikt, lai noteiktu pārbaudes metodes efektivitāti attiecībā uz pārbaudāmajām daļām. Vienu vai otru metožu piemērotību var novērtēt, pamatojoties uz standarta novirzēm un konfidences līmeņiem, kas attiecas uz katru pieeju, ko izmanto konkrētā pārbaudes situācijā. (beigas)
