Dynamic Optimization Software (DyOS)

Dynamic Optimization Software (DyOS) is a software tool for solving multi-stage dynamic optimization problems.
This problem class includes the optimization of operation and control for chemical processes and energy systems, and other related applications.

A large class of dynamic optimization problems involve models given by differential-algebraic equations. DyOS features state-of-the-art numerical solution methods, among them an automatic adaptation of the control profile discretization. DyOS has successfully been used to solve

multi-stage problems,

nonlinear model-predictive control problems,

dynamic optimization problems under uncertainty, and

integrated scheduling and control problems.

Energy system models can be passed to DyOS, e.g., as Functional Mock-up Units. For a comfortable usage of DyOS, interfaces to Python and MATLAB are included.
