Abstract :
Based on the area between the curve of the membership function and the horizontal real axes, a new index, called the expansion center for fuzzy numbers is proposed. An intuitive and reasonable ranking method for fuzzy numbers based on their expansion center is also established. This new ranking method is useful in fuzzy decision making and fuzzy data mining.
