【Abstract】 the existence of fixed-points in fuzzy relations is proved.Some methods for finding thefixed-points as well as the definitions of the walk,bridge and sub-bridge of fixed-points arepresented.It is also proved that fixed-points can be used to calculate transitive closure offuzzy relations,An approved algorithm for calculating the transitive closure is given and thesimulation results show that its speed is higher than that by Warshall′s.更多还原
