“…There are other tools that can contribute to the development of a new model of vehicle replacement optimization, such as, Fuzzy Logic and the Support Vector Machine (SVM): ( [21], [24], [27], [86], [106] and [115]). Regarding predictive maintenance, and specifically the analysis of oils, some mathematical models and concepts were used, which are referenced by the following authors: ( [4], [5], [17], [19], [32], [33], [40], [56], [57], [58], [66], [88], [89], [91], [92], [93], [94], [95], [96], [97], [98], [99] and [116]). [5] justifies the utility and necessity of mathematics in engineering, analysing the main mathematics courses in engineering courses, reflecting on the real or desirable connection between mathematics and engineering courses.…”
