摘要：The fuzzy coloring of a fuzzy graph was defined by the authors in
Eslahchi and Onagh (2004). In this paper we define the
chromatic fuzzy sum and strength of fuzzy graph. Some properties
of these concepts are studied. It is shown that there exists an
upper (a lower) bound for the chromatic fuzzy sum of a fuzzy
graph.
