| abstract        = Defuzzification is the process of converting a fuzzy quantity to precise quantity, just as fuzzification is the conversion of a precise quantity to a fuzzy quantity. Various types of defuzzification methods, are available for conversion of fuzzy to non-fuzzy. In this paper, defuzzification functions in intuitionistic fuzzy environment such as triangular, trapezoidal, L-trapezoidal, R-trapezoidal, Gaussian, S-haped, Z-shaped functions are defined. The proposed defuzzification techniques are useful to develop intuitionistic fuzzy logic controller.&lt;br /&gt;
