The definitions of service-matching degree, composition harmony degree, and cloud-entropy and the corresponding calculation methods are given. A multi-objective optimization mathematical model of cloud manufacturing service composition is built. The manufacturing task of AGV (automated guided vehicle) is taken as an example to verify the proposed CEGA algorithm on the established composition model. The studied result shows that CEGA converges faster than a standard genetic algorithm with shorter timeZa optimizacijo razporejanja proizvodnih virov v oblaku in izboljšanje učinkovitosti sestave storitev proizvodnje v oblaku je bil raziskan problem optimizacije sestave storitev proizvodnje v oblaku. V ta namen je predlagan nov pristop: genetski algoritem, izboljšan z entropijo oblaka (CEGA), ki pri optimizaciji upošteva več ciljev: stopnjo primernosti storitev, stopnjo harmonije sestave in kompleksnost sestave storitev. Podane so definicije stopnje primernosti storitev, stopnje harmonije sestave in entropije oblaka s pripadajočimi računskimi metodami. Postavljen je matematični model večciljne optimizacije sestave proizvodnih storitev v oblaku. Oblikovana je matrika stopnje primernosti storitev na podlagi štirih meril: kapacitete, želje, opreme in lokacijeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
