An Overview of Granular Computing
粒度计算研究综述

Granular Computing(GrC) is an emerging conceptual and computing par information processing. Just as a great umbrella, it may be regarded as a label of theories, methodologies, techniques, and tools that make use of gran- ules, i. e., groups, classes, or clusters of a universe. "GrC" is a superset of the theory of fuzzy information granula- tion, rough set theory, the theory of the quotient space and Interval computing etc, which is a branch of granular math- ematics. It plays an important role in information processing for fuzzy, uncertainty, partial truth and soft computing and is one of the main study stream in A I. This paper summarizes the developed motivations and the research status quo of GrC, lays stress on the introduction of main theoretic models and approaches, then explores applications for va- rious fields using GrC. Finally, we analyze existing problems about Granular Computing and propose the further inves- tigation objects.
