Annotation: The article is devoted to assessing the efficiency of using trian-gular and trapezoidal membership functions in fuzzy systems. Two metrics are proposed: execution time of the fuzzy inference algorithm, dispersion of the output value. The results of exper-iments on testing three fuzzy systems of different architecture complexity are presented: determining the size of a tip for a waiter; forecasting changes in energy consumption in the pro-duction system; driver assistance on the roads.

Keywords: fuzzy inference time, membership functions, fuzzy logic
