Fuzzy location problems on networks

Location problems concern a wide set of fields where it is usually assumed that exact data are known. However, in real applications, the location of the facility considered can be full of linguistic vagueness, that can be appropriately modelled using networks with fuzzy values. Thus fuzzy location problems on networks arise; this paper deals with their general formulation and the description of the ways to solve them. Namely, we show the variety of problems that can be considered in this context and, for some of them, we propose the most operative approaches for their solution.
