Model/4_model.gms¶
GLOBIOM MODEL FILE¶
This is the most important file!
It contains the list of the variables and the equations.
It gives you the definition of the model: MODEL GLOBIOM /``list of equations that are included/``
The code line to run the model starts with SOLVE, e.g.
SOLVE 'Model name'=GLOBIOM USING 'solver'=LP Maximizing 'Objective'= CSPS.
The solver to be used is set via an OPTION LP= statement.
Of the SOLVE directives in this file, the first solves GLOBIOM without
calibration. By default it is skipped (without_free is set) to proceed to two
solves of the GLOBIOM_FORCED model. These are calibration solves for
production cost and trade cost functions in the model that make it possible to
reproduce year 2000 conditions as a starting point for the final GLOBIOM solve.
You can track the calibration process using parameters declared in the
rep_declare_calib.gms file and calculated in the rep_compare_calib.gms file
included after each SOLVE.
More checks are computed in rep_baseyear.gms included at the end of this file.
