Microscopic Disruption Management: Energy Consumption and Passenger Compensation Optimisation

Rail operations are often disrupted by accidents that cause traffic to diverge from the scheduled operations, rendering it difficult run schedule as planned. In such a case, operator must change return original schedule. If passengers delayed, train may have policy of economically compensating them (e.g., refunding ticket fare). Compensation amounts usually determined length delay. As result, is critical smart way determining whether accelerate trains absorb delays, thus increasing energy usage, or compensate passengers. This paper presents mathematical model for speed profile while taking passenger usage into account. The determines best sequence operating regimes and switching points between variety different situations types, all accounting delays compensation policies. aim reduce both amount consumed paid There constraints on traction braking forces, velocity, forces induced vertical horizontal track profile, policy. results computational tests performed practical problem instances Spanish rail RENFE showed. suggested approach capable producing strategies strike an excellent balance managerial objectives.
