Purchase Or Evaluate

The ANSWER-TIMES and ANSWER-MARKAL software is commercial software. Prior to making a decision to purchase, it is possible to obtain a free 60-day evaluation version of the software.

However the ANSWER software does not exist in isolation. The ANSWER software is specialized software specifically developed for working with the TIMES and MARKAL model generators developed by IEA-ETSAP (see www.iea-etsap.org/web/tools.asp) and two other software components are required:

  • The source code for the TIMES (or MARKAL) model generator that is written in the GAMS modelling language, and where ETSAP holds the intellectual property rights. The model generator source code is free, but first a Letter of Agreement acknowledging ETSAP’s intellectual property rights must be executed. See below.
  • The GAMS modelling language software and a suitable GAMS-compatible solver. The GAMS (General Algebraic Modeling System) software is commercial software owned by GAMS Development Corporation, Washington D.C.

Also, if you are interested in purchasing or evaluating ANSWER-TIMES, it is recommended that you also acquire the VEDA-BE results handling software owned by KanORS Inc, India.
