Abstract

Planovi prijema koriste se za statističku kontrolu pošiljki. Bazirani su na AQL-u. Kvaliteta se ocjenjuje preko postotka nesukladnih jedinica. Ako nije zadovoljavajuća pošiljka se ne prihvaća. Kada se radi o nizu pošiljki postotak nesukladnih nešto će varirati, tako da pojam AQL odgovara prosjeku postotka nesukladnih u nizu. Generator postotka nesukladnih u pošiljci je proizvodna tolerancija. Simulacija prihvaćanja niza pošiljki i pripadne OC-krivulje pokazuju da dok je prijem pošiljki oko 95%, planovi su primjenjivi na grafičke proizvode. Kada vjerojatnost prihvaćanja padne ispod 90% planovi prijema postaju neprecizni. OC krivulje govore da je to zbog postotka nesukladnih jedinica. Sa rastom postotka nesukladnih, pada vjerojatnost prijema, međutim pada i preciznost planova, koji su baždareni samo za visoki prijem pošiljki.

Abstract in english:	Sampling procedures are used for statistical control of shipments. They are based on AQL. Quality is graded by percentage of non-conforming units. If not satisfactory shipment is not accepted. When working on, a number of non-conforming shipments percentage will vary slightly, so that the concept of AQL corresponds to the average percentage of non-conforming in order. Manufacturing tolerances are the generator of non-conforming units in the shipment. Simulation of accepting on a series of shipments and associated OC-curves, showed that plans are applicable to the graphics products while acceptance probability are approximately 95%. When acceptance probability drops below 90%, sampling procedures become imprecise. OC-curves suggest that this is due to the percentage of non - conforming units. The probability of acceptance falling down with an increase in the percentage of non-conforming units. The accuracy of plans also falling down. They are calibrated only for high reception shipments.
