Abstract

U ovo radu predstavljeni su načini kontrole proizvoda te planovi uzorkovanja za atribute i varijable. Planovi uzorkovanja za atribute provode se prema normi HRN ISO 2859-1, dok se planovi uzorkovanja za varijable provode prema normi HRN ISO 3951-1. Također, u ovome radu predstavljeni su primjeri planova uzorkovanja za atribute i varijable. Primjeri za atribute izvedeni su za jednostruki i dvostruki plan uzorkovanja po normalnom, pooštrenom i smanjenom režimu kontrole. Primjeri planova uzorkovanja za varijable izvedeni su prema s-metodi za dvostruke povezane granice odstupanja za normalni, pooštreni i smanjeni režim kontrole. U eksperimentalnom dijelu rada provedena je simulacija uzorkovanja u programskom paketu Minitab. Simulacija uzorkovanja atributa provedena je prema jednostrukom planu uzorkovanja za normalni režim kontrole. Simulacija uzorkovanja varijabli provedena prema planu uzorkovanje sa dvostrukim povezanim granicama odstupanja prema normalnom režimu kontrole. Dobiveni rezultati simulacije su analizirani te je izveden zaključak.

Abstract (english)

This paper presents product control methods and sampling plans for attributes and variables. Sampling plans for attributes are carried out according to HRN ISO 2859-1, while sampling plans for variables are carried out according to HRN ISO 3951-1. Also, examples of sampling plans for attributes and variables are presented. Examples for attributes were derived for single and double sampling plan under normal, tightened and reduced inspection. Examples of sampling plans for the variables were derived according to the s-method for combined control of double specification limits for normal, tightened, and reduced inspection. In the experimental part of the paper, a simulation of sampling in the Minitab software package was performed. Attribute sampling simulation was performed according to a single sampling plan for the normal inspection. Variable sampling simulation performed according to the sampling plan of double specification limits according to the normal inspection. The obtained simulation results were analyzed and a conclusion was drawn.
