چکیده

In this paper, we consider the design of large-scale hub-and-spoke transportation networks in a competitive environment. We adopt the hub arc location model that locates arcs with discounted transport costs connecting pairs of hub facilities. Two firms compete for passengers in a Stackelberg framework where the leader firm locates hub arcs to maximize its revenue, given that the follower firm will subsequently locate its own hub arcs to maximize its own revenue. Several mechanisms are presented to allocate traffic between the two firms based on the relative attractiveness of travel via the competing hub networks. Results with up to three hub arcs for each competing firm show the role of a competitive environment in designing transportation systems.

A Stackelberg hub arc location model for a competitive environment

In this paper, we consider the design of large-scale multiple allocation hub-and-spoke transportation networks in a competitive environment. We adopt a generic hub arc location model that locates arcs with discounted transport costs connecting pairs of hub facilities. Two firms compete for customers in a Stackelberg framework where the leader firm locates hub arcs to maximize its revenue, given...

A Multi-Level Capacity Approach to the Hub and Spoke Network

The existing works considering the flow-based discount factor in the hub and spoke problems, assume that increasing the amount of flow passing through each edge of network continuously decreases the unit flow transportation cost. Although a higher volume of flow allows for using wider links and consequently cheaper transportation, but the unit of flow enjoys more discounts, quite like replacing...

ارائه یک روش ابتکاری ترکیبی مبتنی بر الگوریتم ژنتیک برای حل مسأله هاب پوششی در حالت فازی

Hub location problem is one of the new issues in location problems. This kind of location problem is widely used in many transportation  and telecommunication networks. Hubs are facilities that serve as transshipment and switching point to consolidate flows at certain locations for transportation,airline and postal systems so they are vital elements of such these networks. The location and numb...

Reliable hub-and-spoke network design problems under uncertainty through multi-objective programming

HLP (hub location problem) tries to find locations of hub facilities and assignment of nodes to extended facilities. Hubs are facilities to collect, arrange, and distribute commodities in telecommunication networks, cargo delivery systems, etc. Hubs are very crucial and their inaccessibility impresses on network whole levels. In this paper, first, total reliability of the network is defined bas...

A Hybrid Solution Method for Hub-and-Spoke Network Design under Uncertainty

Supply chain is an integrated system of facilities and activities. Gaining the optimum design of demand satisfaction network is one of the most important live issues in the decision making problems category. Most of previous studies considered unreal assumptions such as the lack of capacity constraints to satisfy demand in the network and in hubs. By considering the nature of the case that have...
