In this paper we generalize a standard goal programming (Gf) problem to inv
estigate GP problems with alternatives and goals being fuzzy sets and the s
atisfaction of a goal by a fuzzy goal function defined on alternatives set
is also understood by a fuzzy relation. We propose a unifying approach cove
ring several approaches known from literature. (C) 2000 Elsevier Science B.
