粒度计算模型的研究

粒度计算可以看作是利用粒度解决问题的理论、方法、技术和工具。文中介绍粒度计算的一些基本概念以及研究粒度计算的目的,阐述粒度计算研究的基本问题,分析当前粒度计算研究的几个模型,重点讨论不同粒度世界的描述法———商空间法,并从各种角度对几个模型做出比较,得出它们的联系与区别,证明几种方法各有优劣。

The Research of Model of Granular Computing

Granular computing(GrC) may be regarded as a label of theories,methodologies,techniques,and tools that make use of granules in the process of problem solving.Firstly,this paper introduces some fundamental conception and the research intention of GrC.Secondly,the basic problem of GrC is expounded.Finally,this paper analyzes some GrC models at present.The emphases of this paper is discussing the method of different granular space-quotient space.In addition,this paper compares these models from various angles in order to educe the similarities and differences of various models and prove the respective advantages and disadvantages.
