  1. 6. Prediction of Component Breakdowns in Commercial Trucks : Using Machine Learning on Operational and Repair History Data

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Einar Bremer; [2020]
    Keywords : Machine Learning; Data Science; Neural Networks; Recurrent Neural Networks; Random Forest; Autoencoder; Long Short Term Memory;

    Abstract : The strive for cost reduction of services and repairs combined with a desire for increased vehicle reliability has led to the development of predictive maintenance programs. In maintenance plans, accurate forecasts and predictions regarding which components in a vehicle is in risk of a breakdown is bene_cial to obtain since this enables components to be predictively exchanged or serviced before they break down and cause unnecessary downtime.
