Abstract

Inženjerstvo kvalitete obuhvaća sve aktivnosti koje osiguravaju kvalitetu proizvoda kroz njegov životni ciklus, a to su planiranje proizvoda, konstruiranje proizvoda, razvoj proizvodnog procesa sam proizvodni proces te usluge nakon prodaje. Za razliku od tradicionalne kontrole kvalitete u inženjerstvu kvalitete koriste se složene analize podataka, statističko modeliranje te strojno učenje koji su potpomognuti raznim računalnim programima. R programski jezik je jedan od vodećih programa u tom području te je u ovom radu prikazano njegovo široko područje primjene. Uvodno su prikazani jednostavni alati za kontrolu kvalitete kao što su histogram, kontrolne karte, Paretov dijagram, dijagram uzroka i posljedica te slični. Nakon toga prikazan je postupak prilagodbe teorijske raspodjele podataka empirijskim podacima te je prikazan način izračuna sposobnosti procesa. U nastavku je napravljena analiza kako ocjena sukladnosti proizvoda utječe na podjelu rizika između kupca i proizvođača. Korištenjem Monte Carlo simulacije u posljednjem dijelu rada napravljena je procjena mjerne nesigurnosti i statistička analiza tolerancija.

Abstract (english)

Quality engineering encompasses all activities that ensure the quality of a product throughout its life cycle, namely product planning, product design, process design, production, and service after purchase. Unlike traditional quality control, quality engineering uses complex data analysis, statistical modeling and machine learning that are supported by various computer programs. The R programming language is one of the leading programs in this field, and this paper presents its wide field of application. Introductory, this paper explains simple quality control tools such as histogram, control chart, pareto diagram, the cause and effect diagram etc. After that, the paper is focused on the procedure of fitting distribution to empirical data, as well as the method of calculating the process capability. Following that is an evaluation on how the conformity assessment of a product affects the division of risk between the customer and the producer. In the final part of the paper the focus is on the conformity assessment and statistical analysis of tolerances using the Monte Carlo simulation.
