p-Median problems in a fuzzy environment

David Kutangila-Mayoya, José Luis Verdegay


In this paper a formulation for the fuzzy p-median model in a fuzzy environment
is presented. The model allows to find optimal locations of p facilities and their
related cost when data related to the node demands and the edge distances are
imprecise and uncertain and also to know the degree of certainty of the solution. For
the sake of illustration, the proposed model is applied in a reduced map of Kinshasa
(Democratic Republic of Congo) obtaining results which are rather than realistic
