Adaptive Sampling of Dynamic Systems for Generation of Fast and Accurate Surrogate Models [PDF]
Chemie-Ingenieur-Technik, 2021 AbstractFor economic nonlinear model predictive control and dynamic real‐time optimization fast and accurate models are necessary. Consequently, the use of dynamic surrogate models to mimic complex rigorous models is increasingly coming into focus. For dynamic systems, the focus so far had been on identifying a system's behavior surrounding a steady ...

Surrogate Modeling with Gaussian Processes for an Inverse Problem in Polymer Dynamics
International Journal of Computational Methods, 2022When rheological models of polymer blends are used for inverse modeling, they can characterize polymer mixtures from rheological observations. This requires repeated evaluation of potentially expensive rheological models. We explored surrogate models based on Gaussian processes (GP-SM) as a cheaper alternative for describing the rheology of ...

Surrogate Modelling for Efficient Discovery of Emergent Population Dynamics
2019 International Conference on High Performance Computing & Simulation (HPCS), 2019Outcomes of simulating complex systems models, such as emergent properties and desirable system level behaviours, can be discovered via heuristic techniques such as Genetic Algorithms (GAs). Using simulation as the cost function evaluation for a GA (i.e. simulation guided search) is computationally expensive.

Dynamic Surrogate Reservoir Model with well constraints
2016 3rd International Conference on Computer and Information Sciences (ICCOINS), 2016Reservoir flow calculation is a significant aspect in oil and gas industries to calculate the results of a reservoir. Due to the large number of grid blocks and heterogeneity in reservoir models, extensive simulations are required to reduce the risk in reservoir's productivity.

Dynamic structure response using surrogate models
2019Environmental vibrations are a well-known problem that can cause annoyance and even have negative health effects to the exposed population. Using surrogate models for the estimation of vibrations is an attractive alternative to costly numerical modelling or on-site measurements.
