✦ Synopsis

In 2002, Chu and Tsao proposed a method to rank fuzzy numbers. They employed an area between the centroid and original points to rank fuzzy numbers; however there were some problems with the ranking method. In this paper, we want to indicate these problems of Chu and Tsao's method, and then propose a revised method which can avoid these problems for ranking fuzzy numbers. Since the revised method is based on the Chu and Tsao's method, it is easy to rank fuzzy numbers in a way similar to the original method.

To improve the ranking method of Lee and Li [1], Cheng [2] proposed the coefficient of variation (CV index). Shortcomings are also found in the CV index. Cheng [2] also proposed the distance method to improve the ranking method of Murakami et al. However, the distance method is not sound either. Mor
