Abstract. By coupling computer with measurement devices, information measurement systems are being made, whose basic tasks are automation measuring and quality control of manufacturing processes, mathematical processing of measured results in real time, storing of measured results, documenting of measured results, process management, etc. Statistical methods for quality evaluation provide analyses of production processes which can serve as the basis for undertaking adequate preventive and correction measures in order to increase the total production quality. In this paper importance is emphasized for applying statistical quality control methods to evaluation of process stability and capability. There is a preview of structure and functioning of the developed applicative software for statistical process control. At the end, corresponding conclusions are given.
Key Words: Statistical Process Control, Process Stability, Process Capability.
RAZVOJ SISTEMA ZA STATISTIČKU KONTROLU KVALITETA PROIZVODNIH PROCESA
Sprezanjem računara i mernih uređaja stvaraju se informacioni merni sistemi, čiji su osnovni zadaci automatizovano merenje i kontrola kvaliteta proizvodnihh procesa, matematička obradu rezultata meranja u realnom vremenu, memorisanje mernih rezultata, dokumentovanje rezultata merenja, upravljanje procesima, itd. Statističke metode za ocenu kvaliteta omogućavaju analizu proizvodnih procesa a na osnovu iste i sprovođenje odgovarajućih preventivnih i korektivnih mera u cilju podizanja ukupnog kvaliteta proizvodnje. U radu je istaknut značaj primene statističkih metoda kontrole kvaliteta za ocenu stabilnosti i sposobnosti proces. Prikazana je struktura i finkcionisanje razvijenog aplikativnog sofvera za statističku kontrolu procesa. Na kraju su dati odgovarajući zaključci.
Ključne reči: statistička kontrola procesa, stabilnost procesa, sposobnost procesa
