Advanced Analytics: Modeling and Optimization with GAMS

April 03-05, 2019 – Vienna, Austria

Implement advanced analytics by using GAMS (General Algebraic Modeling System) for modeling and solving optimization problems.



The course is for you if you need to

  • advance your analytics skills by building your own models for custom analysis
  • get an overview of mathematical optimization
  • learn how to use GAMS to solve real-world optimization problems
  • understand, enhance, and modify existing GAMS models Course language

The training seminar covers

  • the foundations of mathematical programming
  • basics of modeling and optimization solution algorithms
  • working with the GAMS IDE
  • how to map decision problems in business and science to the basic objects of optimization models: indices, data, variables, constraints, and objective functions
  • how to analyze results and identify key influencing factors in complex models
  • how to analyze and understand existing models
  • where to look for more information efficiently

All course material will be in English. The default course language is English and can be switched to German if (and only if) all participants prefer it.



  • USB-stick with a printed copy of the course material
    • the course material
    • the example model library used throughout the course including solutions to the exercises
    • the latest GAMS system and an unlimited-size temporary license with several solvers
  • Business lunches as well as coffee breaks with snacks & beverages


    • A notebook or laptop computer running Windows® for learning and practicing in and out of class
    • While GAMS is available for a wide range of platforms and operating systems, we will use the GAMS IDE for the course which only runs on Windows®. Administrator rights might be needed for installing the software.
    • If you don’t have GAMS installed we will install it at the beginning of the course, including the course license.
    • Basic experience with computers: familiarity with the concept of files and directories, ability to install software.

      • Structure
      • The GAMS Integrated Development Environment (GAMS IDE)
      • First modeling exercise
    • GAMS Language 1: Objects in Optimization
      • Data Objects: Sets, Scalars, Parameters, Tables
      • Variables
      • Equations
      • Models and Model Attributes
      • Output Files, Debugging

    I’d like to thank you for the training course, also on behalf of the project team. It made a lasting and good impression on all of us. I am convinced that the information we got leaves us well positioned for the further course of our project.

    Host of in-house course, German energy company

    Very nice – looking for future workshops!

    2017 course participant, Vienna

    Dr. Maindl provided a lot of cases to help me to understand the new language. The most useful thing is that this course provides not only practical modelling, but also the theoretical background of each model. Because of this, I can apply GAMS to my research well. I really appreciate his lecture.

    Dr. J. Shin, 2018

    Professor, South Korea

    The course was really nice and I had opportunity to learn a lot from this. I learned GAMS for the first time in my life and it is a very powerful tool. I am really thankful for the course.

    Thank you so much for the great course, the exercises, … It was indeed very nice!
