A note on “The revised method of ranking LR fuzzy number based on deviation degree”

Recently, Asady [(2010). The revised method of ranking LR fuzzy number based on deviation degree. Expert Systems with Applications, 37, 5056–5060] pointed out that Wang et al.’s method has some drawback by a numerical example and then Wang’s method is modified to present an easy way to rank fuzzy numbers. In this note, we will indicate that Asady’s revision has a shortcoming exactly as the same as Wang’s method.
