VEDA-BE User Guide

The VErsatile Data Analyst is a software dedicated to the analysis of data and results obtained from a broad variety of mathematical models or data bases. VEDA is a powerful and user friendly tool for the construction of analyst tables and graphs to help in the analysis of results from complex mathematical models. 

VEDA is suitable for any GAMS-based model built on the concept of Sets for identifying and grouping model components and parameters for the management of numeric values, including those provided by the user to the model, derived in GAMS code as part of the model preparation and/or reporting procedures, as well as those obtained from the model solution (e.g. the primal and dual solution values obtained from optimization). Any GAMS-based model can be linked to VEDA by means of the GDX2VEDA utility and the associated <application>.VDD VEDA definition file. Appendix A discusses the GDX2VEDA Data Definition File in some detail.

In this manual, examples are taken from the World SAGE[1] model, which is one variant of the generic MARKAL family of models[2]. The manual is also fully compatible with the TIMES model as well, and illustrative of how VEDA can be used with most GAMS models...
