Actually, I think this is a pretty neat demonstration. Of course, the clue to
this particular multi-valued logic is the statistical independence of you
microevents. But suppose they are not independent? If the correlation between
the microevents is as positive as possible, you will get the Zadeh max-min
logic; if it is as negative as possible, you will get A AND B = max(0, a + b -
1) and A OR B = min(A+B, 1), etc. As I have reported elsewhere, Jim Buckley and
I have a paper coming out in Fuzzy Sets and Systems which extends this line of
thought to a family of multi-valued logics which can obey the laws of Excluded
Middle and Contradiction.
As Earl says, the fact that you note has been known for a long time, but nobody
pays any attention to it. Believe me, that is not the stuff that is known, at
least by those of us who actually construct fuzzy expert systems, that nobody
pays any attention to.
