Betreff: Arithmetic operations with fuzzy numbers


is there anybody, who can help me in the field of arithmetic operations =
using fuzzy numbers?

I have to divide two fuzzy numbers (a triangular or trapecial shaped =
fuzzy number should be divided by a fuzzy number with an EXP-shaped =
membership-function) and sum up the resulting fuzzy numbers (also =
EXP-shaped membership-functions).

- Is it correct to use ALPHA-cuts?
- Is there any software-support in this field (for I am a student I=B4m =
especially interested in free- or shareware products)?
- I=B4m also interested in literature concerning this problem.

You can reach me at the follwing address:
