Abstract

Rail road switch heaters are used to avoid the formation of snow and ice on top of rail road switches during the cold season, in order to guarantee their correct functioning.

Effective management of the energy consumption of these devices is important  to reduce the costs and minimise the  environmental impact. While doing so, it is critical to guarantee the reliability of the system.

In this seminar reliability and energy consumption indicators for a system of (remotely controlled) rail road switch heaters are analysed by developing and solving a stochastic model-based approach based on the Stochastic Activity Networks (SAN) formalism. An on-off policy is considered for heating the switches, with parametric thresholds of activation/deactivation of  the heaters and considering different classes of priority.
