Optimizacija montažnega in strežnega sistema delavniške proizvodnje s pomočjo digitalnega dvojčka : zaključna naloga Razvojno raziskovalnega programa I. stopnje StrojništvoGrgurič, Jurij, strojnikZa optimiziranje procesov, ki so v današnji industriji čedalje kompleksnejši in vedno bolj avtomatizirani, se ne moremo več zanašati na preproste izračune in izkušnje. Zato vedno pogosteje ... uporabljamo diskretne simulacije, ki predstavljajo digitalni dvojček realnega sistema. S pomočjo simulacije lahko preizkušamo različne scenarije, tudi povsem hipotetične, ne da bi motili realni sistem. Problem delavniške proizvodnje (angl. JSSP) predstavlja elementarno težavo planiranja zaporedja proizvodnje različnih naročil. Cilj optimizacije je bil najti zaporedje naročil, v katerem bodo vsi proizvodi končani v cim krajšem času. Naš 10-dimenzionalni problem smo optimizirali naključno in z genetskim algoritmom. Z obema metodama smo pridobili enak najboljši rezultat (2 d 8 h 44 min), kvalitativno pa smo lahko vrednotili le konvergiranega, ki ga je pridobil genetski algoritem. Ta se je izkazal kot dobro orodje simulacijske optimizacije, saj v kratkem času preveri veliko število permutacij, s pomočjo mutacij in križanja pa relativno hitro in z zadostno stopnjo gotovosti najde aproksimacijo optimalne vrednosti. Prav zaradi enostavnosti, hitrosti in relativne natančnosti ostaja med vodilnimi algoritmi optimizacije aplikativnih simulacij.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [j.
