The company performs serial production characterized by complex and diverse technologies, alternative solutions and combined modes of workpiece movement in the manufacturing process. Because of various approaches to this problem, an analysis of previous investigations has been carried out, and a theoretical base is provided for the technological cycle and factors affecting the manufacturing cycle time. The technological and production documentation of the company has been analysed to establish the technological and real manufacturing cycle times, total losses and flow coefficients. This paper describes the original approach to production cycle scheduling on the grounds of investigations of manufacturing capacity utilization levels and causes of loss, in order to measure their effects and to reduce the flow coefficient to an optimum level. The results are a segment of complex studies on the production cycle management of complex products, accomplished in the company in the period from 2010 to 2012Članek podaja rezultate raziskave časovne dimenzije časa proizvodnega cikla sestavnih delov kompleksnih izdelkov. Rezultati predstavljajo del zahtevne raziskave upravljanja s proizvodnim ciklom kompleksnih izdelkov, ki se je začela 2010 ter je bila zaradi svojega pomena, obsega in zahtevnosti problematike razdeljena na več faz. Raziskave so z ozirom na teoretične predpostavke in industrijsko prakso osredotočene na čase ciklov v pogojih ponavljajoče se serijske proizvodnje, kjer lahko zaradi kompleksnih in raznovrstnih tehnologij prihaja do zastojev. Tehnološke proizvodne operacije, s katerimi se spreminjajo oblika in lastnosti obdelovancev, se tukaj prekrivajo z neproizvodnimi operacijami. Tehnološke operacije so jasno diferencirane: v proizvodnem ciklu se uporabljajo tako visokoproduktivni stroji za standardne in posebne namene, kjer so zgoščene tehnološke operacije, kakor tudi univerzalna oprema. Za proizvodnjo je značilno kombinirano gibanje obdelovancev po korakih procesaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
