We consider a hub-and-spoke network design problem with congestion. The model we propose extends current models by taking congestion effects into account. This is achieved through a non-linear cost term in the objective function. We first linearize the model, and then provide a Lagrangean ...

Motivated by the strategic importance of congestion management, in this paper we present a model to design hub-and-spoke networks under stochastic demand and congestion. The proposed model determines the location and capacity of the hub nodes and allocate non-hub nodes to these hubs while ...
Recently, hub-and-spoke networks employing central hub facilities to channel flows between interacting nodes have become popular with successful applicatio... Aykin,Turgut - 《Transportation Science》 被引量: 326发表: 1995年 Hub-and-spoke network design with congestion We consider a hub-and-spoke ...
This paper develops a mathematical program with equilibrium constraints (MPEC) model for the intermodal hub-and-spoke network design (IHSND) problem with multiple stakeholders and multi-type containers. The model incorporates a parametric variational inequality (VI) that formulates the user equilibrium ...
distinguished from the conventional hub-and-spoke network design (HSND) problem and its variants (O’Kelly, 1987; Campbell, 1994), due to its unique characteristics elaborated below. In addition to locating hubs, as addressed in the conventional HSND problem, the IHSND problemneeds to identify ...
China Railway Express is developing rapidly, but the point-to-point direct organization mode has brought many problems to it. Therefore, this paper proposes to construct a hub-and-spoke network and a...
This study presents a biobjective hub-and-spoke (HS) network design model for the global air passenger networks. The model explores the tradeoff between the total airline cost (airline preference) and lost time cost for passengers (user preference) as the model’s objectives. Most previous studie...
The multiple allocation hub-and-spoke network design under hub congestion problem is addressed in this paper. A non-linear mixed integer programming formulation is proposed, modeling the congestion as a convex cost function. A generalized Benders decomposition algorithm has been deployed and has success...
