As a multi-criteria analysis method, PROMETHEE has a long and fruitful history. Developed in the '80s by Jean-Pierre Brans and his collaborators, many scholars have been using and further refining the method over the years. Today, PROMETHEE is still being used a lot within decision making in research settings but also in business contexts. With the PROMETHEE days, which started in 2014, the applications and further developments on the method are again shared on a regular basis. This special issue is the result of the second PROMETHEE days. The workshop was held in Brussels on the 23rd of January 2015, at the Universite libre de Bruxelles (ULB) and organised by Yves De Smet and Cathy Macharis and their respective teams. It gathered 30 participants from nine countries. Twenty-two papers were presented.
