20.500.12556/RUL-106464 Digital twins understanding the added value of integrated models for through-life engineering services Digital twins are digital representations of physical products or systems that consist of multiple models from various domains describing them on multiple scales. By means of communication, digital twins change and evolve together with their physical counterparts throughout their lifecycle. Domain-specific partial models that make up the digital twin, such as the CAD model or the degradation model, are usually well known and provide accurate descriptions of certain parts of the physical asset. However, in complex systems, the value of integrating the partial models increases because it facilitates the study of their complex behaviours which only emerge from the interactions between various parts of the system. The paper proposes that the partial models of the digital twin share a common model space that integrates them through a definition of their interrelations and acts as a bridge between the digital twin and the physical asset. The approach is illustrated in a case of a mechatronic product - a differential drive mobile robot developed as a testbed for digital twin research. It is demonstrated how the integrated models add value to different stages of the lifecycle, allowing for evaluation of performance in the design stage and real-time reflection with the physical asset during its operation. digital twin modelling multi-domain model digitalni dvojček modeliranje večdomenski model true false true Angleški jezik Slovenski jezik Članek v reviji 2019-02-25 13:37:43 2019-02-25 13:37:46 2022-08-19 03:46:01 0000-00-00 00:00:00 2018 0 0 f. 139-146 Vol. 16 2018 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 004.9(045) 2351-9789 10.1016/j.promfg.2018.10.167 16492059 16492315 RAZ_Vrabic_Rok_i2018.pdf RAZ_Vrabic_Rok_i2018.pdf 1 E7267D2D8F12F85274B5122FCA71ED40 9d013598c9a93609a88e29b46fd4a7059c601d7d0149b6bec330aa919c8fd0e3 55989fd0-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=117236 https://www.sciencedirect.com/science/article/pii/S2351978918312897?via%3Dihub#! 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=117237 Fakulteta za strojništvo 0 0 0
