20.500.12556/RUL-178114 Z digitalnim dvojčkom do optimalne postavitve in logistike proizvodnje v podjetju Unior Optimizing production layout and logistics using a digital twin at Unior Prispevek prikazuje uporabo digitalnega dvojčka kot ključnega orodja za optimizacijo tlorisov in notranje logistike v podjetju UNIOR. Zaradi zaprtja ene izmed proizvodnih enot je bilo potrebno preseliti več strojev in tehnologij na dve obstoječi lokaciji, pri čemer je bil cilj zagotoviti učinkovito razporeditev brez dodatnih gradbenih posegov. Z uporabo digitalnega dvojčka smo izvedli natančne simulacije, analizirali različne scenarije in optimizirali materialne tokove, kar je omogočilo povečanje števila izvedenih operacij za več kot 320 %, skrajšanje poti materialov za 43 % ter odpravo potrebe po zunanjih logističnih storitvah. Primerjava z začetno rešitvijo, pripravljeno pred začetkom optimizacije, je pokazala, da pristop z digitalnim dvojčkom vodi do bistveno boljše učinkovitosti, boljše izrabe prostora in racionalizacije notranje logistike. Prispevek ne prikazuje le uspešnega primera reorganizacije proizvodnih kapacitet, temveč tudi dokazuje, da je digitalni dvojček nepogrešljivo orodje pri optimizaciji in reorganizaciji obstoječih proizvodnih postavitev v sodobnem industrijskem okolju. This paper presents the optimization efforts at the company UNIOR. Following the closure of one of its production units, it was necessary to relocate several machines and technologies to two existing locations, with the goal of achieving an efficient arrangement with minimal construction interventions. Using the digital twin, we conducted precise simulations, analysed various scenarios, and optimized material flows, which enabled a more than 320% increase in the number of operations performed, a 43% reduction in material transport distances, and the elimination of the need for external logistics services. To support analysis and decision-making, we also used Sankey diagrams, which visualized the intensity and direction of material flows and significantly contributed to identifying bottlenecks and selecting the optimal layout. A comparison with the initial layout, developed based on expert knowledge without the use of simulation tools, showed that the digital twin approach leads to significantly better efficiency, improved space utilization, and more streamlined internal logistics. The paper not only presents a successful case of production capacity reorganization but also demonstrates that the digital twin is an indispensable tool for optimizing and reorganizing existing production setups in modern industrial environments. digitalni dvojčki optimizacija proizvodnje postavitev proizvodnje notranja logistika prilagodljiva proizvodnja pametne tovarne true false false Slovenski jezik Angleški jezik Članek v reviji 2026-01-19 10:26:00 2026-01-19 10:26:01 2026-01-20 04:23:58 0000-00-00 00:00:00 2025 0 0 Str. 162-167 št. 3 Letn. 31 jun. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 658.5:004 1318-7279 242501379 zupan_07-2025.pdf zupan_07-2025.pdf 1 B1F1F05B5CDF623BC746296838281695 2c41cdc98f614269cf625c74b600194b0d0866ba13c42de6f9dddd01d4ba161c 317496ae-f519-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225666 https://revija-ventil.si/wp-content/uploads/zupan_07-2025.pdf 0 61af5bdf-f519-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225668 Fakulteta za strojništvo Ventil 0 0 0
