Document Abstract
In the present paper, we find lower bound of functional mean code word length in fuzzy set with existing knowledge of
different code word length. We know that lower bound of functional mean code word length is measure of fuzzy entropy which
satisfy all different properties of itself. By finding lower bounds of different mean code word length, different measure of
entropies in fuzzy set can be found which are very important in present .
Keywords: Mean code word length, Kraft’s inequality, measure of entropy and fuzzy entropy, measure of directed divergence
