We have a 30-year experience in implementing our PROMETHEE & GAIAmethods in software:
A first implementation was realized at the ULB at the end of the 1980's. It was named PROMCALC and it was running under MS-DOS. It was one of the first really interactive software based on outranking methods.
At the end of the 1990's Decision Lab was developed in a joint venture between the ULB and the Canadian company Visual Decision.
Today VPSolutions proposes the Visual PROMETHEE software. It is the only PROMETHEE-based software developed under the supervision and backed by the authors of the PROMETHEE & GAIA methodology.
