This course will systematically explain the basic theory, basic methods and application of the grey system, which was first introduced in 1982 by J.L. Deng at Huazhong University of Science and Technology. The content of the course is the quintessence of the course group's long-term theoretical exploration, practical application and teaching practice. It also absorbs the theories and applications obtained by domestic and foreign colleagues in recent years. The main content includes the basic concepts and basic principles of grey systems, sequence operators and grey data mining, grey incidence analysis, grey cluster evaluation models, GM series models, grey combination models, grey system forecasting technology, etc.
This course has been selected as the National Excellent Course in 2008, and as the National Excellent Resource Sharing Course in 2012; besides, it was selected as the National Excellent Online Open Course in 2018, and National first-class undergraduate courses in 2020. The supporting textbooks were selected as the "Eleventh Five-Year" and "Twelfth Five-Year" national planning textbooks and the "Famous Masterpiece Series" of Science Press. In 2017, it was rated as the No. 1 Highly Cited Book of Natural Sciences by CNKI in 1949-2009
Through online courses, students will systematically master the basic theories and methods of grey system, be able to use grey system modelling software proficiently, have the ability to analyze and solve practical problems, and the wisdom of innovative thinking.
On September 7, 2019, German Chancellor Angela Merkel gave special praise to China’s original grey system theory in a speech at Huazhong University of Science and Technology. He praised the work of Professor Deng Julong, the founder of Grey System Theory, and Professor Liu Sifeng, the head of this course, ‘profoundly affect the world’.
