Hi Bertrand, I have a quick question. Suppose we have the following PROMETHEE modelling: *The criterion is minimized *The difference between objects 'a' and 'b' on that particular criterion is -5, i.e. d of (a-b) = -5 * V-shape preference function with P-threshold of 6 is selected. How do we calculate the P (a,b)? Will it be 5/6 since we minimized the criterion so that the preference function should be reversed? Many thanks your time!

Hello,

You are right. As the criterion has to be minimized, a is better than b and a positive preference degree value of 5/6 is computed. That is done automatically in the software.
