Digital Twins in Complex Systems
Research Guide
What is Digital Twins in Complex Systems?
Digital Twins in Complex Systems are real-time virtual replicas of physical systems enabling simulation, prediction, and optimization in systems engineering.
Grieves and Vickers (2016) introduced digital twins to mitigate unpredictable emergent behavior in complex systems, cited 2778 times. Madni et al. (2019) integrated digital twins into model-based systems engineering (MBSE), with 920 citations. Bachelor et al. (2019) applied digital twins to aeronautical systems lifecycle management, garnering 93 citations.
Why It Matters
Digital twins enable predictive maintenance in manufacturing and aerospace by synchronizing virtual models with physical assets (Grieves and Vickers, 2016). In offshore crane operations, they simulate dynamics under wave influences for safer designs (Fotland et al., 2019). Madni et al. (2019) show digital twins enhance MBSE for lifecycle optimization in safety-critical systems. Perabo et al. (2020) demonstrate their use in ship propulsion modeling via open simulation platforms.
Key Research Challenges
Synchronization with Physical Assets
Maintaining real-time data alignment between physical systems and digital replicas faces latency and sensor inaccuracies. Grieves and Vickers (2016) highlight this for mitigating emergent behaviors. Madni et al. (2019) note integration challenges in MBSE workflows.
Modeling Emergent Behaviors
Predicting nonlinear interactions in complex systems requires advanced simulation techniques. Grieves and Vickers (2016) address undesirable emergences in digital twins. Schluse et al. (2017) emphasize experimentable twins for MBSE validation.
Scalability in Interdisciplinary Design
Integrating multi-domain models across engineering disciplines demands unified frameworks. Graessler et al. (2018) extend V-models for mechatronics. Bachelor et al. (2019) tackle this in aeronautical thread concepts.
