Fuzzy decision-making is one of the important branches of fuzzy set theory, proposed firstly by Bellman and Zadeh in 1970, and fuzzy mathematical programming is one of the effective methods of fuzzy decision-making, introduced firstly by Zimmermann in 1978. The basic theory of fuzzy decision-making is described in detail by the reviewer in his new book `Fuzzy Sets and Fuzzy Decision-Making', CRC Press (1995). The author has contributed to fuzzy nonlinear programming since 1990 and in this paper some relationships between the concept of efficient and weak-efficient solutions of multiobjective convex nonlinear programming problems are considered, especially the relation between the fuzzy solution of the general fuzzy problem and the fuzzy optimal point for the special fuzzy problem.
