The PROMETHEE-GAIA multicriteria decision aid methodology has been developed by Professor Jean-Pierre Brans and myself at the ULB and VUB universities of Brussels since 1982.


For an introduction to the basic principles of PROMETHEE and GAIA or for more resources related to the methodology, you can consult the web site.


The PROMETHEE and GAIA methods have been implemented by their authors in different software :


  • PromCalc in the 1990's,
  • Decision Lab in the 2000's, (developed by the Canadian company Visual Decision under a collaboration agreement with our department)
  • Visual PROMETHEE which is currently available for download from the web site.


The PROMETHEE Days 2016 annual workshop took place in Montréal, Canada, on May 2-4, 2016, together with the Optimization Days 2016 international conference.


The PROMETHEE Days 2017 workshop took place in Portsmouth, UK, this month.


The PROMETHEE Days 2018 will be held in Heraklion, Greece, on May 22-25, 2018.
