I am trying to solve a Multi Criteria Decision Making problem using The PROMETHEE Method, and I have come across PyDecision Library for Python that contains all PROMETHEE Versions, Yet in their Colab demo they have used an abstract example that has only Beneficial Criterions.

Let's say I want to solve this problem:

Alternat Cost (NB) RAM (B) Storage (B)
Phone1 500 $ 16 GB 64 GB
Phone2 350 $ 8 GB 32 GB

Cost: is a non-beneficial criterion because we want to minimize its value. Ram & Storage: are Beneficial criterions because we want to maximize these values.

So, is there a way to present the type of criterion to PROMETHEE?

  • I'm not a domain expert, but... is there any reason you couldn't just negate the costs? – user2357112 Dec 25 '22 at 14:30
  • I thought about doing that tbh, but in theory PROMETHEE works with 2 different formulas, one if the criterion is Beneficial and the other formula if it is non-beneficial. – nanitoo Dec 25 '22 at 14:34
