摘要：

We show that by using the theory of possibility distribution, multivalued dependencies in fuzzy relations can be expressed in the frame work of particularization. Another definition of functional dependencies in a fuzzy relation is given in terms of fuzzy Hamming weight. We have also discussed the validity of inference rules for multivalued dependencies in fuzzy relations.
