The GAMS Model Library

The models in the GAMS Model Library have been selected because they represent interesting and sometimes classic problems. Examples of problems included in the library are production and shipment by firms, investment planning, cropping patterns in agriculture, operation of oil refineries and petrochemical plants, macroeconomics stabilization, applied general equilibrium, international trade in aluminum and in copper, water distribution networks, and many more.

Another criterion for including a model in the library is that it illustrates the modeling capabilities GAMS offers. For example, the mathematical specification of cropping patterns can be represented handily in GAMS. A further example of the system 's capability is the style for specifying an initial solution as a starting point in the search for the optimal solution of dynamic nonlinear optimization problems.
