“…Recent studies have also developed numerous statistical analysis methods and concepts for fuzzy theory (Fan, 2010;Hsu, Tsai & Chiang, 2009;Ravi, Shankar, Sireesha, Rao & Vani, 2010;Sun & Wu, 2007;Wang & Chen, 2010;Wu & Lin, 2002). The second part involves the examining of the interval fuzzy number method to expand the applicability of the theory (Chu & Lin, 2009;Hung, Vladik, Wu & Gang, 2011;Lin & Chen, 2004;Sengupta & Pal, The Study of Taiwan's New Immigrant Children's Mathematics Achievement 37 2000; Yager, Detyniecki & Bouchon-Meunier, 2001). The third part includes research documents on the sorting of fuzzy numbers.…”
