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.
