Optimizing Travel Time and Regenerative Energy for Periodic Timetables
A bicriteria model (PESP-Passenger-Energy) is introduced to optimize periodic timetables for passenger travel time and regenerative energy recovery, proving NP-hardness on one-station networks while identifying polynomial-time cases.
