Abstract

For a given Transportation Problem, several assumptions can be considered on the supply and demand levels. In accordance with the kind of information the decision maker has, s/he may express those values in many ways. Here three situations are considered: the decision maker can exactly define them as point values, s/he can give them as interval values or, if s/he has vague information, express them as fuzzy numbers. For each of these three cases, different models (classical, interval and fuzzy) of the Transportation Problem may be obtained, respectively. This paper deals with these three different models. The links among them are provided, focusing on the case of the Fuzzy Transportation Problem, for which methods of solution are proposed and discussed.
