Abstract
Ordinal fuzzy switching functions are calculated by max, min and (1-x) operators.Logical Choquet integrals are calculated by Choquet integral instead of max-min calculations.Logical Choquet integrals satisfy lots of good properties such as the complementary laws, monotonicity when the function is monotonicity with binary inputs and so on.To demonstrate the properties, 3 examples, `Fuzzy XOR', `friendship and power' and `Evaluation of 3 subjects' are given.
