Notebooks

Demo: Cooling Tank Model uses the SampleApproach class to model human interactions with the modeled system (in model_main.py).
Paper: Optimization Architecture Comparison shows how design and contingency management of a system (in model_optimization.py) can be co-optimized with the ProblemArchitecture class, as well as external solvers.

The support files include various implementations of the tank model.

The baseline Tank Model (model_tank.py), a dynamical implementation of a human-operated tank system to show how fmdtools can be used to model human errors.
A demonstration Optimization Tank Model (model_optimization.py), along with resilience optimization architectures using ProblemArchitecture.
