Hao-ran Lin , male, graduated from the Department of Mathematics, Shanghai Normal University in 1968, has long been engaged teaching in middle school mathematics . Since 1997, by using teaching materials, he tried fuzzy mathematics enlightenment and popularization work first in ordinary middle schools and published twenty papers in the "Mathematical Bulletin", "People's Education", "Shanghai Education" and other core journals in mathematics education in China. He propagandized enlightenment to secondary school students by popularization of fuzzy mathematics necessary and possible.In 2003 he was named the top ten annual figures in Shanghai education. In 2005, he asked Professor of L.A. Zadeh , the founder of fuzzy mathematics, of University of California, whether the English version of this textbook could be published, which has formed the book today.
