摘要：
It is often necessary to join (naturally) two or more fuzzy relations to answer a user's query. However, the result of a join may not be what one expects. In this paper, we study the decomposition problem of fuzzy relation schemes. We show that the algorithm proposed by A. V. Aho et al. to test lossless join decomposition for classical relations can be applied in the fuzzy domain when particularizations are induced by functional dependencies.
