Hi everybody,
Can anyone tell me anything about results on sensitivity analysis in fuzzy
systems (and perhaps give me some references). I've read a few fuzzy
papers, but surprisingly enough I have encountered nothing related to this
important issue.

are there any general results on

(a) the robustness of fuzzy logic expert systems?
(b) what happens with output if more membership functions are added to the
(c) what happens with output if the shapes of the membership functions are
changed a bit?
And finally,
(d) is there a standard stability-check procedure for fuzzy expert systems?
