Granularity research based on panweighted field of pansystems

In order to study granularity, this paper aims to discuss how to construct granules from the view of panweighted field of pansystem.

By changing the panweights of panweighted field – subdivision of panweights, increase/decrease of panweights and reallocating panweights, to construct proper granules is the approach taken.

This paper provides a new method of studying granularity. If the weights of panweighted field are subdivided, then the granularity diminishes; if the panweights of panweighted field are increased, then the corresponding granularity diminished. Contrarily, the decrease of panweights of panweighted field results in the corresponding granularity increased; by reallocating panweights, use different method to construct different granules, such as compatible class, neighbor operator, compatible core, s‐s core and so on.

How to reallocate panweights is the main limitation.

A very useful advice for studying granularity.

This paper combines the granularity with panweighted field of pansystem, and studies granularity from the view of panweighted field of pansystems.
