New Algorithms for Trapezoidal Approximation of Fuzzy Numbers Preserving the Expected Interval

Przemyslaw Grzegorzewski.

Fuzzy number approximation by
trapezoidal fuzzy numbers which
preserves the expected interval is
discussed. New algorithms for calculating
the proper approximations
are proposed. It is shown that
the adequate approximation operator
is chosen with respect both to
the global spread of a fuzzy number
and the size of possible asymmetry
between the spread of the left-hand
and right-hand part of a fuzzy number.
