Distributed optimization approaches for the integrated problem of real-time railway traffic management and train control
(2019)Linköping Electronic Conference Proceedings ~ RailNorrköping 2019. 8th International Conference on Railway Operations Modelling and Analysis (ICROMA), Norrköping, Sweden, June 17th – 20th, 2019This paper introduces distributed optimization approaches, with the aim of improving the computational efficency of an integrated optimization problem for large-scale railway net-works. We first propose three decomposition methods to decompose the whole problem into a number of subproblems, namely a geography-based (GEO), a train-based (TRA), and a time-interval-based (TIN) decomposition respectively. As a result of the decomposition, ...Conference Paper -
An optimization model for rescheduling trains to serve unpredicted large passenger flow
(2019)Linköping Electronic Conference Proceedings ~ RailNorrköping 2019. 8th International Conference on Railway Operations Modelling and Analysis (ICROMA), Norrköping, Sweden, June 17th – 20th, 2019As the separation of vertically-integrated organizations in railway transportation, not only the competitive but also the collaboration between different operating companies and different modes should be considered emphatically in the rapidly changing multimodal transportation market. This paper tries to solve the Train Timetable Problem for serving Unpredicted Large Passenger Flow causing by the stop of air traffic in collaborating with ...Conference Paper -
A train timetabling and stop planning optimization model with passenger demand
(2019)Linköping Electronic Conference Proceedings ~ RailNorrköping 2019. 8th International Conference on Railway Operations Modelling and Analysis (ICROMA), Norrköping, Sweden, June 17th – 20th, 2019Train timetabling plays an important part in train management, not only for passengers, but also for train operators. In a highly dynamic transportation market, train timetabling is an essential bridge connecting the service supplier with transportation demand. However, in present operations, train scheduling without considering passenger demand can reduce competitive advantages of railway in the multimodal transportation market and will ...Conference Paper
