This study applies the Mamdani fuzzy inference system to assess the suitability of EVs based on six key variables: price, production year, driving range, passenger capacity, power, and battery capacity. Triangular membership functions are used to represent the linguistic variables, and the rule base reflects realistic decision preferences. Through fuzzification, Mamdani inference, aggregation, and defuzzification, crisp suitability scores are produced for each vehicle. Results show that EVs with high specifications and proportional prices achieve the highest scores, while those with high prices but low specifications rank lowest. The fuzzy Mamdani approach effectively integrates linguistic and subjective criteria to support structured decision-making in EV selection.</p> Ikha Puspita Parwitasari, Azis Putra Setyawan ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 https://ejurnal.undana.ac.id/index.php/JD/article/view/25024 Wed, 31 Dec 2025 04:46:51 +0000
