Fuzzy reliability analysis in the implementation of geographic information systems

We use fuzzy logic for proposing a classification model which divides a geographic map into isoreliable zones. This classification is based on a software tool called FUZZY-SRA (spatial reliability analysis) integrated in a geographical information system (GIS) of the PROCIDA island, located near Naples (Italy). The GIS is realized with technology of the Environmental Systems Research Institute and the logical operations, for processing the linguistic approximations and the classification of the zones, are defined in the context of an algebraic structure, already known in literature.
