Granular computing: examples, intuitions and modeling

摘要

The notion of granular computing is examined. Obvious examples, such as fuzzy numbers, infinitesimal number and access control model, (pre-) topological spaces are examined. A general models are proposed; localized multi-level granulation can be modeled by generalized topological spaces, called neighborhood systems. For most general granulation are modeled by Tarski type relational structures.
