Fuzzy systems. The fuzzy logic [ 1, 2] has been derived from the conventional logic, i.e., the fuzzy set theory. The fuzzy logic consolidates the smooth transformation between false and true. Instead of presenting the output as extreme ‘0’ or ‘1,’ the output results in the form of degree of truth that includes [0, 1]. citizen shippers
