Researchers have developed a new framework for mitigating error propagation in modular digital twins by treating it as a sequential decision-making problem. They formulated this using a Markov Decision Process (MDP) and a Partially Observable MDP (POMDP) to account for imperfect state classification. The MDP policy demonstrated superior performance in maintaining system fidelity and nominal operation, while the POMDP achieved nearly equivalent results under realistic noise conditions. AI
