Grey analysis then comes to a clear set of statements about system solutions [specify]. At one extreme, no solution can be defined for a system with no information. At the other extreme, a system with perfect information has a unique solution. In the middle, grey systems will give a variety of available solutions.
Liu is an honorary fellow of the World Organisation of Systems and Cybernetics, [6] and an honorary editor of "International Journal of Grey Systems" (USA). [7] German Chancellor Angela Merkel mentioned Liu's contributions to grey system theory in a 2019 speech at Huazhong University of Science and Technology. [8]
Deng Julong (Chinese: 邓聚龙; 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 ...
This list of types of systems theory gives an overview of different types of systems theory, which are mentioned in scientific book titles or articles. [1] The following more than 40 types of systems theory are all explicitly named systems theory and represent a unique conceptual framework in a specific field of science .

[8] [9] These have special analysis methods. In particular linear regression techniques [10] are much more efficient than most non-linear techniques. [11] [12] The model can be deterministic or stochastic (i.e. containing random components) depending on its planned use.

McClelland, "Systems and History in International Relations," General Systems Yearbook, III (1958). The General Systems Yearbook also contains examples of the third kind of general systems activity — creating new laws and refining old. [3]
Open systems have input and output flows, representing exchanges of matter, energy or information with its surroundings. An open system is a system that has external interactions. Such interactions can take the form of information, energy, or material transfers into or out of the system boundary, depending on the discipline which defines the ...
