This method is also applicable for piece-wise continuous fuzzy numbers or the fuzzy numbers which are only continuous from right or only continuous from left. The core of fuzzy numbers should have a singleton set.</p> <p><strong>Keywords: </strong>Continuous fuzzy number; piece-wise continuous fuzzy number; Maximum (MAX) and Minimum (MIN) of fuzzy number; core; &alpha;-cut; bounded increasing and bounded decreasing functions; membership function.</p> <p><strong>GANIT </strong><em>J.
