Large model facilities

GAMS is not the tool of choice for small, infrequently solved problems.  In such cases, the generality of the presentation may not be worth the effort, and spreadsheet or other formulations are probably quicker and easier to deal with.  GAMS is best employed for medium or large sized models (more than 100 rows and/or columns) and can handle large problems as the table of a few or my application model sizes below indicates.

The gains to using GAMS rise with problem size and complexity of the model use exercise study.  When a modeler deals with large problems, the GAMS algebraic statement is probably the only thing that is thoroughly understood.  Often the numerical formulation has grown out of control.
