Choosing the location of a global logistic hub for reaching a new market can be considered as a “facility locationproblem” addressed through optimization based on quantitative criteria, or as a multi-criteria decision makingproblem using both quantitative and qualitative criteria. The second approach has been chosen for consideringthe real case of a logistic provider in Africa. The first originality of this article is to suggest a global frameworkpositioning the different types of criteria that may be used, based on an analysis of the relationships between theconcept defining the decision making context. For assessing the various decision criteria, an important re-quirement of the company was to reuse when possible assessments coming from trustable external sources,mainly international organization indexes (World Bank, World Economic Forum, etc.), and to complete themwith knowledge coming from internal experts. This knowledge being often imprecise and uncertain, FuzzyTOPSIS, often used for Multi Criteria Decision Making, is chosen as a global methodology. The standard methodhas been modified on two important points: (1) a new fuzzy distance is suggested to measure the differencebetween two solutions, allowing to postpone the defuzzification process until the end of the reasoning, (ii) ameasure of confidence has been added to each elementary assessment, allowing the experts to clearly distinguishthe fuzziness of an evaluation (“around 10”) and the possibility that this evaluation is wrong. We show in anillustrative example how taking into account this new distance and the suggested confidence level may yieldricher results than the standard method.
