CGE Modelling: Course Software


The courses use the General Algebraic Modeling System (GAMS) software. The text editor used is GAMS Studio (included with the GAMS programme) and all data are handled using GAMS Data Exchange (GDX) and MS Excel.

It is not necessary to buy GAMS for these courses; the Practical course only requires the Demo/Student version of GAMS and the GAMS corporation provide (time limited) licences for participants on the other courses offered.

The GAMS software can be download from here. Please ensure you download the correct version for your PC.

We will not use GAMSIDE for the courses in 2022-23, so ensure you choose to install the GAMS Studio version.

Operating System

The instructions assume you are using a Windows PC with Windows 8.1, or later.

We believe that GAMS Studio, GAMS GDX and MS Excel all operate with full functionality on Apple Macs with x86 64 bit Mac OS X. (We will test the Apple Mac version during 2022).

The courses are not set up for LINUX operating systems, although there are versions of GAMS compatible with LINUX systems. We have not, and will not test the LINUX versions.

Microsoft Office

The courses use MS Excel for providing (some) model data and for downloading results data MS Excel is very useful for tabulating and graphing model results. A word processor, e.g., MS Word, will be needed to complete the assignments.


MOODLE is accessed through the internet. During the courses participants will have access to all the course materials (course programme, video presentations, PowerPoint slide shows, various ‘how to’ guides, technical and teaching documents, practical (CGE and other) computer exercises, and  GAMS libraries containing all the GAMS codes and databases used during the course) via the Moodle Cloud site.
