The machine learning model may be trained to optimize the temporal cost function of sustained service interruptions and forecast ETRs for service interruptions (in minutes). The machine learning model may process data/information in real-time and provide an ETR when inputs are not yet available in the repair/resolution process, and update (reforecast) the ETR in real-time as the inputs late become available.
