A new effect of radius of gyration with neural networks
In 2006, Deng etal. (Comput Math Appl 51: 11271136, 2006) proposed a method to evaluate DMUs. A radius of gyration was employed to rank fuzzy numbers; however, there were some problems with the ranking method. This paper attempts to reveal the issues of Dengs method and proposes a revised method that can avoid these problems for ranking fuzzy numbers. Since the revised method is based on Dengs method, it is easy to rank fuzzy numbers in a way similar to the original method.
