Dear Biscers:

You may have received Professor Zadeh's message. A new BISC
special interest group Granular Computing (GrC) is being formed.
If you have any suggestions and comments, please send e-mail to
T.Y. Lin (Tsau Young Lin) at "" and
CC to Professor Zadeh at "".

We have set up an account for GrC. If you are interested in
joining the Group please send e-mail to:

Will be provided. Tentatively send to:

Please use "Join GrC" as the subject of the mail, and include the
following information in the body if possible:

Enclosed please find information about GrC. Your comments and
suggestions are appreciated. Please feel free to contact us.

2. Scope

"GrC is a superset of the theory of fuzzy information
granulation, rough set theory and interval computations,
and is a subset of granular mathematics."
--- Lotfi. A. Zadeh

Professor Zadeh pointed out many times that the success of fuzzy
logic rests on two essential notions, granulation (together with computing
with words) and fuzzification. The latter has been well studied in
classical fuzzy set theory. The former is a very natural concept and
appears almost everywhere by different names, such as data compression,
divide and conquer, chunking, interval computations, neighborhood systems,
and rough sets among others, just to name a few. However, the notion
of information granulation has not been fully explored in its own right.
We hope the GrC Special Interest Group can explore, organize and unify
these divergent concepts, theories, and applications into a well
formulated theory of granular computing.

3. Activities

3.1. Online Workshops
Brain Storming Online Workshops will be organized.
If participants think we have high quality discussions, we
will organize special issues in various journals.

3.2. Online Abstracts
We will accept abstracts online continuously until we reach a
certain volume. Then an Online workshop will be held to
discuss these abstracts. Again, by participants decision,
we may organize a special issue.

3.3. Possible Future Actions
If the group feels we have sufficient substance, we may organize
our own Journal.
