Background: This paper introduces an enhanced multi-period p-mobile hub location model that accounts for critical factors such as service time, flow processing delays, and congestion impacts at capacity-constrained hubs. As (urban) transportation networks evolve, mobile hubs play an increasingly...

In transportation systems with mobile and modular facilities, decisions related to facility location and facility capacity management during the planning horizon are critical; because the parameters effective in these decisions change over time, and it is necessary for the decision-maker to...

Motivated by recent antitrust cases, a hub-and-spoke collusive mechanism involving multiple downstream firms and their common upstream supplier is explored. To this end, I develop a repeated sequential game in which downstream firms receive private demand signals and send private messages to the...

In distribution systems such as airlines and express package delivery, the use of hub-and-spoke networks is common, and flow consolidation at hub facilities is essential for cost reduction. While a constant discount factor is typically used to model cost reduction in interhub links, this paper...

We introduce a novel multimodal (ground and air transportation) network design model with transshipments for the transport of express cargo with heterogeneous service classes (i.e., next morning delivery, and next day delivery). We formulate this problem using a novel path-based mixed-integer...

We examine two factors that might explain the extent of air traffic delays in the United States: network benefits due to hubbing and congestion externalities. Airline hubs enable passengers to cross-connect to many destinations, thus creating network benefits that increase in the number of...

Background: The purpose of this paper is to develop a generic transport system for same-day delivery that is suitable for matching long-distance bulk distribution with local distribution. Methods: The innovative concepts of this research entail the introduction of mobile hub (MH) networks in...

Background: Nowadays, variable domination structure is instrumental in studying multiobjective decision making problems. We investigate multiobjective location problems with respect to variable domination structure and its applications in supply chain management. Methods: We formulate practical...

Considering the influence of economies of scale and ship capacity on empty container repositioning, using foldable containers and container leasing may be effective ways to save the operating costs of liner shipping companies. Considering the minimization of the transportation costs of empty and...

The Hub-and-Spoke network is a defining feature of the airline industry. This paper is among the first in the literature to introduce an empirical framework for analyzing network competition among airlines. Airlines make market entry decisions and choose flight frequencies in the first stage,...

This paper compares two possible formats for free trade in the Americas: a system of spokes surrounding a U.S. hub, and a free trade area. The paper identifies the sources of welfare change, and it argues that a country's attitude towards a system depends on whether the arrangement is a...

Wholesale-retail hub and spoke cartels usually combine a horizontal collusive behaviour between competitors and the involvement of at least one hub, who operates at a different level of the supply chain and facilitates the collusion, and some forms of vertical restraints, typically RPM or, in...

Numerous recently uncovered cartels operated along the supply chain, with firms at one end facilitating collusion at the other - hub-and-spoke arrangements. These cartels are hard to rationalize because they induce double marginalization and higher costs. We examine Canada's alleged bread cartel...

We analyze a hub-and-spoke cartel in the Brazilian automotive fuel industry. Using the court documents and detailed data on the supply chain we uncover three mechanisms beyond information sharing used by wholesalers (hub) to help retailers (spokes) solve the obstacles of price coordination:...

Hub-and-spoke (HS) networks are cost-effective because they allow the realization of economies of density. However, the cost of point-to-point (PP) networks may be lower than that of HS networks when certain conditions, such as cargo demand, bunker price, vessel size, and the shippers’ value...

Entrepôts are hubs that facilitate trade between multiple origins and destinations. We study these entrepôts, the network they form, and their impact on international trade. We document that the trade network is a hub-and-spoke system, where 80% of trade is shipped indirectly--nearly all via...

Reasonable layout of logistics centers in the ASEAN countries has important practical significance for improving logistics network efficiency and reducing logistics transportation costs. This paper based on the current status of the ASEAN logistics network and the characteristics of the...

One of the important tools to increase supply chain productivity and reduce logistics costs is to establish logistics hubs. Since there is no logistics hub in the central region of Iran, this study was conducted to identify a suitable area for a logistics hub in Isfahan province. In this line,...
