Modeling ExtensionsΒΆ
The IDAES platform includes several modeling extensions that provide additional capabilities including surrogate modeling, material design, and control. A brief description of each is provided below.
PySMO: Python-based Surrogate Modeling Objects
PySMO: Python-based Surrogate Modeling Objects provides tools for generating different types of reduced order models. It provides IDAES users with a set of surrogate modeling tools which supports flowsheeting and direct integration into an equation-oriented modeling framework. It allows users to directly integrate reduced order models with algebraic high-fidelity process models within an single IDAES flowsheet.
OMLT: Optimization and Machine Learning Toolkit
OMLT: Optimization and Machine Learning Toolkit provides tools for generating machine learning, neural network and gradient-boosted tree models with the Pyomo optimization environment. It provides IDAES users optimization formulations for ML models (e.g. full-space, reduced-space, MILP) and an interface to import Sequential Keras and general ONNX models.
Note
OMLT is an external tool that requires additional dependencies. See the OMLT documentation for details on installation and usage.
ALAMOPY: ALAMO Python
ALAMOPY: ALAMO Python provides a wrapper for the software ALAMO which generates algebraic surrogate models of black-box systems for which a simulator or experimental setup is available.
Note
ALAMO is an external tool to needs to be installed separately. See the ALAMOPy documentation for details on ALAMO installation and usage.
RIPE: Reaction Identification and Parameter Estimation
RIPE: Reaction Identification and Parameter Estimation provides tools for reaction network identification. RIPE uses reactor data consisting of concentration, or conversion, values for multiple species that are obtained dynamically, or at multiple process conditions (temperatures, flow rates, working volumes) to identify probable reaction kinetics. The RIPE module also contains tools to facilitate adaptive experimental design.
HELMET: HELMholtz Energy Thermodynamics
HELMET: HELMholtz Energy Thermodynamics provides a framework for regressing multiparameter equations of state that identify an equation for Helmholtz energy and multiple thermodynamic properties simultaneously.
MatOpt: Nanomaterials Optimization
MatOpt: Nanomaterials Optimization provides tools for nanomaterials design using Mathematical Optimization. MatOpt can be used to design crystalline nanostructured materials, including but not limited to particles, wires, surfaces, and periodic bulk structures.
Caprese
Caprese is a module for the simulation of IDAES flowsheets with nonlinear program (NLP)-based control and estimation strategies, namely Nonlinear Model Predictive Control (NMPC) and Moving Horizon Estimation (MHE).
Uncertainty Propagation Toolbox
Uncertainty Propagation Toolbox is a module for quantifying and propagating parametric uncertainty through an optimization or simulation problem based on an IDAES model.
