The Grey Systems Theory Framework
2016Over the past 30 years, grey systems theory has developed as a scientific discipline with its own theoretical structure consisting of systems analysis, evaluation, modeling, prediction, decision-making, control, and techniques of optimization.

Introduction to Grey Systems Theory
2010On the basis of dividing the spectrum of scientific and technological endeavors into finer sections, the overall development of modern science has shown the tendency of synthesis at a higher level. This higher level synthesis has caused the appearance of the various studies of systems science with their specific methodological and epistemological ...

The hybrid intelligent systems design using grey systems theory
Grey Systems: Theory and Application, 2015Purpose – The purpose of this paper is to discuss how tacit and explicit knowledge determine grey knowledge and how these are stimulated through interactions within networks, forming the grey hybrid intelligent systems (HISs).

Application of grey system theory in telecare
Computers in Biology and Medicine, 2011As a superiority to conventional statistical models, grey models require only a limited amount of data to estimate the behaviour of unknown systems. Grey system theory can be used in the effective factor assessment, and used in large samples where data are not available or uncertain whether the data was representative.

SAR Image despeckling using grey system theory
2007 IEEE International Conference on Grey Systems and Intelligent Services, 2007Speckle noise appears in synthetic aperture radar (SAR) images owing to the SAR imaging mechanism. This paper investigates and proposes a novel method on SAR images despeckling via grey system theory. In the method, we dynamically select one referential sequence to stand for inner region pixels, and a group of comparative sequences to represent the ...

Application of grey system theory in China
[1990] Proceedings. First International Symposium on Uncertainty Modeling and Analysis, 2002The conceptions, aims and applications in China of grey system theory are introduced. Some mathematical notions, such as the status of grey systems in grey number terms, the differences between grey numbers and interval numbers and the relation between grey numbers and real sets, are considered. >

Grey system theory in China: A bibliometrics analysis
2009 IEEE International Conference on Grey Systems and Intelligent Services (GSIS 2009), 2009Using the method of bibliometrics, a 1982~2006 Grey Systems database was constructed for China from National Knowledge Infrastructure(CNKI). Gather documents with Grey System contained in their titles, by analyzing the year, institution, journal, high citation frequency, theme, subject, output manner etc.

Advances in grey systems theory and its applications
2007 IEEE International Conference on Grey Systems and Intelligent Services, 2007The scientific background that grey systems theory comes into being, the astonishing progress that grey systems theory has made in the world of learning and its wide employment in many scientific areas are presented in this paper. We compare grey systems theory with other kinds of uncertain information such as stochastic uncertainty, uncertainty, fuzzy
