Abstract

Zaradi stalnih sprememb na trgu izdelkov se morajo podjetja hitro prilagajati, da ostanejo konkurenčna in ohranijo rentabilnost. Eden od pristopov je fleksibilna proizvodnja, ki je zmožna hitrega reagiranja glede na potrebe trga, tako da je možna izdelava različnih izdelkov na isti liniji - mešani model proizvodnje. S tem se pojavi nov problem, kako določiti pravi vrstni red naročil, ki določa najkrajši pretočni čas. Naročila morajo biti izdelana v določenemu roku oziroma, tako da je izdelava za proizvodni sistem najugodnejša. Težavo se rešuje z digitalnim dvojčkom proizvodnega sistema in digitalnimi agenti. Pri tem pa se porajata vprašanji, katero simulacijsko orodje izbrati za izdelavo digitalnega dvojčka in kako implementirati digitalnega agenta s pripadajočim optimizacijskim algoritmom. V magistrskem delu smo obravnavali izdelavo digitalnega dvojčka Demonstracijskega centra pametna tovarna v programu Visual Components. Razvili smo digitalni dvojček z novim algoritmom, ki izvaja ne-sprotno simulacijo za različne vrstne rede naročil in predlaga tistega, ki določa najkrajši čas proizvodnje oziroma izvedbe naročil. Algoritem je implementiran kot nov simulacijski element v digitalnem dvojčku, ki iz sprejetih naročil samodejno generira različne vrstne rede izvajanja, jih simulira, analizira, primerja in zapiše rezultate.

Secondary title:	Product order sequence optimization with a digital twin constructed in simulation software Visual Components
Secondary abstract:	Because of constant changes on product market production companies have to quickly adapt so that they stay relevant and continue operate profitably. One of solutions is flexible manufacturing, which allows fast reaction on such changes, with possibility of producing completely different products on same production line at the same time also called mixed production model. With this concept a new problem arises, how to choose appropriate order of products so that throughput time is short as possible. Solution to this problem is constructing digital twin and using digital agents. Main issue is choosing right simulation software according to our needs and implementation of an algorithm. In master's thesis we focused on this issue. For our subject of analysis hybrid production system Demonstration center smart factory was chosen, for which we implemented off-line digital twin in simulation tool Visual Components. Digital twin simulates order optimization and offers best possible solution. Algorithm is implemented as additional element in digital twin itself that generates different scenarios of an order, simulates, analyzes, compares them and lastly writes results.
