An interactive method for multiobjective linear programming problems with interval coefficients

In the context of multiobjective linear programming (MOLP) problems where there is indetermination around some parameters, the authors suppose that the decision maker knows only the limits of variation of these parameters and eventually one of their central values. For such situations, they have proposed a general methodology which enables us to transform the nondeterministic MOLP problem into a deterministic one and to solve the latter program by an interactive approach derived from the STEM method. In the present paper the authors develop a particular method based on that general methodology and we illustrate it by a didactive example.
