Granular Computing: Information hiding and integration

Granular compuitng have three semnatic views: uncertainty mathematics, konwledge engineeering and methodology of computing (how-to-solve-it) In this paper, a theoretical issue on "how-to-solve-it" is raised and formalized. Some suprised phenomena are observed; if "information structures" are considered with the universe and granules, then the solution integrations may not be unique. In other words, there may have more than one integrated structures for a given internal structures of granules and quotient structure.
