FUZZY SETS AND SPATIAL CHOICE∗

Abstract

ABSTRACT Vagueness and ambiguities in individual perception pose conceptual and technical problems in the study of spatial choice. These problems may be attributed partially to deficiencies in the set-theoretic structures underlying our models of spatial cognition and evaluation. L. Zadeh's theory of fuzzy sets provides an explicit account of such ambiguities. The potential of this account includes applications in the areas of algebraic and probabilistic choice theory, distance perception, and in temporal and population aggregation.
