Abstract

A rule-based Mamdani max–min fuzzy expert system for prediction of coefficient of motion resistance (CMR) is presented. Owing to nonlinear characteristic of soil–wheel interactions, application of fuzzy rule-based models for determination of CMR is instrumental. We were encouraged to apply fuzzy logic approach for the modeling by use of the experience of induced CMR as affected by tire inflation pressure, velocity, and wheel load to be practically applicable with wide range of unknown nonlinear systems. Employment of fuzzy if–then true rules makes it possible to handle ill-defined and nonlinear arrangements and gives higher privilege over conventional methods. Therefore, of aforementioned rules, 27 if–then true rules were incorporated to develop a sophisticated highly intelligent representation based on centroid method for defuzzification stage preceded by Mamdani max–min inference supposition. The model performance was evaluated on the basis of various statistical criteria and also was compared to a conventional model. Mean relative error lower than 10 %, good scattering around line (1:1), and high coefficient of determination (R 2 = 99 %) obtained by the fuzzy logics model are confirmed.
