A Train Scheduling for Energy Optimization: Tehran Metro System as a Case Study

IEEE transactions on intelligent transportation systems (Print), 2023
Energy efficiency is one of the main issues in designing and operating different electrical systems. Energy-saving in electrical railway systems is an important concern due to the high amount of used energy.

An integrated approach of train scheduling and rolling stock circulation with skip-stopping pattern for urban rail transit lines

Transportation Research Part C: Emerging Technologies, 2021
Integrated planning for urban rail transit (URT) systems is a significant technique in URT operation to balance service level and operating cost. It is generally oriented towards transportation efficiency and solved in a sequential way due to the ...

An Integrated Train Scheduling Optimization Approach for Virtual Coupling Trains

2022 IEEE 25th International Conference on Intelligent Transportation Systems (ITSC), 2022
As a state-of-the-art train control technology, virtual coupling provides a flexible and efficient operation scheme for urban rail transits. In this paper, an integrated train scheduling method is proposed to obtain the optimal coupling strategy and ...

Train routing and timetabling problem for heterogeneous train traffic with switchable scheduling rules

Transportation Research Part C: Emerging Technologies, 2017
This paper proposes a mathematical model for the train routing and timetabling problem that allows a train to occasionally switch to the opposite track when it is not occupied, which we define it as switchable scheduling rule. The layouts of stations are

Modeling and solving the last-shift period train scheduling problem in subway networks

, 2021
Train arrivals and departures should be scheduled over a certain period when talking about train timetabling problems. For the midnight train operations, passengers significantly concern about the network transfer issue.

Class Scheduling for Pilot Training

Operations Research, 2004
In this paper, we study the class scheduling problem at the training center of Continental Airlines. When pilots get new assignments, they must be retrained for up to eight consecutive weeks. During that time, they are removed from the roster, and thus impose a significant cost on the airlines. We formulate the problem with the objective of minimizing

An actor-critic deep reinforcement learning approach for metro train scheduling with rolling stock circulation under stochastic demand

Transportation Research Part B: Methodological, 2020
This paper presents a novel actor-critic deep reinforcement learning approach for metro train scheduling with circulation of limited rolling stock. The scheduling problem is modeled as a Markov decision process driven by stochastic passenger demand.

Energy-Efficient Subway Train Scheduling Design With Time-Dependent Demand Based on an Approximate Dynamic Programming Approach

IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2020
Owing to environmental concerns, the energy-efficient subway train scheduling problem is necessary in subway operation management. This paper designs an approximate dynamic programming (DP) approach for energy-efficient subway train scheduling problem ...
