Examples

Picture showing the shower problem case with animations containing hot and cold streams, a plot with operable and non-operable regions and goverving equations for the shower problem case. — Co-current Direct Methane Aromatization Reactor (DMA-MR) schematic ^[1].

The examples above use process operability functions/capabilities extensively for different tasks, such as:

Obtaining operability sets
Evaluation of the Operability Index (OI)
Inverse mapping of operability sets
Finding an optimal design
Ranking of competing design/control structures using the OI as a metric

MATLAB® Process Operability App

Such examples employ the multimodel and nonlinear programming-based approaches [1]. Additional documentation and files are available for reproduction of the examples.
