In a process where transportation has gained so much importance, it is important to regularly perform maintenance and repair of vehicles for comfortable, safe and fast transportation. In this study, it is aimed to improve the maintenance and repair times of Kocaeli Metropolitan Municipality tram operation. Therefore, Maintenance Repair Data Model is designed by applying K-NN (K-nearest neighbors) classification, Decision Trees and Deep Learning algorithms from Data Mining algorithms.Thus, the warranty periods of the trams are extended and the trams operate with maximum performance by looking at the mean time between failures and the length of maintenance work periods.Quantitative findings revealed that the K-NN algorithm achieved the highest performance with an accuracy rate of 87.6%, outperforming the Decision Tree 85.95% and Deep Learning 70.66% models. Moreover, the K-NN model demonstrated the most balanced classification performance, with a precision of 0.716, recall of 0.637, and an F1-score of 0.652. In contrast, the Deep Learning algorithm exhibited lower performance, with an F1-score of only 0.355, indicating its limited effectiveness when applied to structured maintenance data. These results suggest that in cases where the dataset is structured and relatively small in scale, simpler non-parametric models such as K-NN may offer more efficient and practical solutions for predicting maintenance durations.}, number={2}, publisher={Kocaeli Üniversitesi}
