Abstract: Selecting a set of potential facility sites is a difficult multi-criteria issue and the objectives weighting is a critical part of the decision making process. However, in order to include as much information as possible, analysts usually try to combine the opinions of several experts. This paper work presents a hybrid approach based on the actual conditions of a case study and on the opinions of four industrial Tunisian experts. The overall objective of this paper is to consider multi-criteria to calculate global priority weights using the fuzzy analytic hierarchy process (FAHP) and PROMETHEE method. After that, a new multi-objective facility location/allocation problem model, which combines FAHP-PROMETHEE and mathematical programming (MP), namely the PROMETHEE-MP model, is tested. The novelty of the proposed model is the simultaneous combination of relevant factors, which are difficult to interpret and cost factors which require network distribution.

Keywords: location/allocation problem; criteria weighting; expert opinions; FMCDM; FAHP-PROMETHEE; PROMETHEE-MP.
