Deng Julong

Deng Julong (; January 1933 – June 22, 2013) was a professor of Huazhong University of Science and Technology, Wuhan, China. He is acknowledged as the founder of grey system theory, first proposed in 1982 with the publication of his paper “Control problems of grey systems,” in the international journal ''Systems and Control Letter'', edited at the time by Roger W. Brockett, a professor at Harvard University. This theory underlies the theory of grey relational analysis. His theory inspired many noted scholars like Jeffrey Yi-Lin Forrest, Liu Sifeng, Wang Jianwei, and Keith W. Hipel, recipient of Izaak Walton Killam Memorial Prize. Provided by Wikipedia
