Abstract The Goal Programming (GP) is one of the well known multiple objectives programming models. The GP model was applied in quite large number of fields. It was qualified as easy to understand and to use by the practitioners. The different GP formulations consider the goals associated to the objectives as deterministic, imprecise, fuzzy or stochastic. It is worth to note that the literature shows that these formulations deal differently with the decision-maker’s preferences. In fact, many ways are proposed for modeling the decision-maker’s preferences in GP. Moreover, in some GP variants the decision-maker’s preferences are totally absent. The aim of this work is precisely to examine how the decision-maker’s preferences are taken into account in the different variants of the GP model.
