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.
