Engineering Contradiction Analysis
1Measurement precision
If traditional simulation methods are used to study complex systems, then computational detail and geometric fidelity can be achieved, but computational cost becomes prohibitively expensive
Solution Approach 1:
The patent creates simplified surrogate models that copy the essential behavior of complex simulation systems. These surrogate models are trained on simulation data and can reproduce key outcomes at a fraction of the computational cost, enabling rapid experimentation and sensitivity analysis without running full expensive simulations repeatedly.
Solution Approach 2:
The patent segments the simulation workflow into distinct phases: (1) running expensive high-fidelity simulations to generate training data, (2) training surrogate models on this data, and (3) using the trained surrogates for subsequent analysis. This segmentation allows the computationally intensive tasks to be performed once, while subsequent analyses use the inexpensive surrogate models.
2Adaptability or versatility
If traditional simulation codes with low-level mechanistic components are used, then detailed system behavior can be modeled, but the models become non-differentiable and lead to intractable likelihoods
Solution Approach 1:
The patent replaces the traditional mechanistic simulation code with a machine learning-based surrogate model. These ML models are inherently differentiable and can compute gradients efficiently, enabling the use of gradient-based optimization and inference methods that are intractable with traditional non-differentiable simulation codes.
Solution Approach 2:
The patent changes the fundamental parameter representation from discrete mechanistic components to continuous probabilistic parameters that can be optimized via gradient descent. This allows the model to remain flexible in representing system behavior while becoming computationally tractable through differentiable programming.
3Reliability
If traditional simulation approaches are used for sensitivity and uncertainty analyses, then comprehensive system understanding can be pursued, but the analyses become impractical due to computational expense
Solution Approach 1:
The patent uses surrogate models as copies of the expensive simulation system specifically for sensitivity and uncertainty analyses. These surrogate copies can be queried thousands of times with negligible computational cost, enabling comprehensive sensitivity analyses and uncertainty quantification that would be impossible with the original expensive simulations.
4Measurement precision
If simulators are used with high geometric details and complex physics, then accurate system representation is achieved, but the number of simulator runs must be limited due to computational constraints
Solution Approach 1:
The patent segments the modeling task into two parts: a high-fidelity simulation run once to generate training data, and a surrogate model that can be executed many times. This segmentation preserves the accuracy benefits of high-detail simulations while enabling numerous runs through the inexpensive surrogate.
