Optimization Problem MPS Files

One can expect from any GEMS interpreter to export the fully assembled optimisation problem in a standard mathematical programming format MPS. The exported file contains the complete linear or mixed-integer formulation constructed from the system configuration, model libraries, and input data.

This export is primarily intended for verification, debugging, and external analysis of the optimisation problem.

A GEMS interpreter generates a MPS file in the study output directory. This functionality is available only in the Antares Modeler interpreter. The GemsPy interpreter does not currently have a native function for this purpose; using the dedicated method of the underlying OR-Tools object that represents the optimisation problem is one possible way to export the MPS file.

The MPS file follows the naming convention {year}-{block}.mps, where year is the Monte Carlo year number and block is the optimization block number. For example, 1-1.mps corresponds to year 1, block 1.

The file is typically overwritten each time the study is executed.
