Solving discrete network design problem using disjunctive constraints

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 8, Page 1028-1042, 18 March 2025.
Abstract This paper introduces a deterministic algorithm to solve the discrete network design problem (DNDP) efficiently. This non‐convex bilevel optimization problem is well‐known as an non deterministic polynomial (NP)‐hard problem in strategic transportation planning.

Integrated scheduling of gantry cranes, container trucks and yard cranes in on‐dock railway operation areas at multimodal container ports

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
This paper investigates an integrated scheduling problem for gantry cranes, container trucks and yard cranes in on‐dock railway operation areas at sea‐rail container ports. This paper proposes an integer programming model using the space‐time‐state network and develops a reformulation‐then‐optimization solution approach.

EQUILIBRIUM TRAJECTORIES FOR CONTROL SYSTEMS WITH HETEROGENEOUS DYNAMICS

Ural Mathematical Journal
The paper considers the construction of equilibrium in bimatrix games with heterogeneous dynamics of players' interaction. Heterogeneity of dynamics is connected with difference in maximal rates of the participants.

Network‐Wide Calibration of Link Capacities for Dynamic Traffic Assignment Models

Journal of Advanced Transportation, Volume 2025, Issue 1, 2025.
Dynamic traffic assignment (DTA) models are used in many transportation planning and traffic management scenario analyses today. The aim of the DTA model is to reproduce the pattern of vehicular movements. DTA models require inputs in terms of demand and capacity of the road network and are very challenging to calibrate for large urban networks.

Trends and Advances in Urban Logistics Research: A Systematic Literature Review

Journal of Advanced Transportation, Volume 2025, Issue 1, 2025.
It is important to establish appropriate performance indicators so that decision‐makers can better determine the best alternatives for sustainable urban freight distribution systems. This literature about urban logistics and routing problems is structured and analyzed through a systematic literature review of a total of 201 papers from 2002 to 2023 ...

Aggregation formulation for on‐site multidepot vehicle scheduling scenario

Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 20, Page 3030-3062, 15 October 2024.
Abstract The multidepot vehicle scheduling problem (MDVSP) is a fundamental public transport challenge. To address the large‐scale model and inherent solution symmetry associated with the traditional trip‐to‐trip connection‐based approach for MDVSP, a new trip‐to‐route (T2R) connection‐based approach is proposed.

Massively Parallel Dantzig-Wolfe Decomposition Applied to Traffic Flow Scheduling [PDF]

, 2009
Optimal scheduling of air traffic over the entire National Airspace System is a computationally difficult task. To speed computation, Dantzig-Wolfe decomposition is applied to a known linear integer programming approach for assigning delays to flights ...
