Euclidean Hub-and-Spoke Networks
The hub-and-spoke distribution paradigm has been a fundamental principle in geographic network design for more than 40 years. One of the primary advantages that such networks possess is their ability to exploit economies of scale in transportation by aggregating network flows through common sources. In this paper, we consider the problem of designing an optimal hub-and-spoke network in continuo...
متن کاملHub-and-spoke Free Trade Areas
Hub-and-Spoke Free Trade Areas* This paper analyzes how the sequential formation of free trade areas affects the volume of trade between member countries. In a three--country, three-good model, if two countries have a free trade area, and both sign a similar agreement with the third, trade between the two decreases, and welfare rises in both. However, if only one of them signs an FTA with the t...
متن کاملThe Reliable Hub-and-spoke Design Problem: Models and Algorithms
This paper presents a study on reliable single and multiple allocation hub-and-spoke network design problems where disruptions at hubs and the resulting hub unavailability can be mitigated by backup hubs and alternative routes. It builds nonlinear mixed integer programming models and presents linearized formulas. To solve those difficult problems, Lagrangian relaxation and Branch-and-Bound meth...
متن کاملThe Hub and Spoke Paradigm for CSR Evaluation
In this paper, we introduce the new paradigm used in the most recent ARPA-sponsored Continuous Speech Recognition (CSR) evaluation and then discuss the important features of the test design. The 1993 CSR evaluation was organized in a novel fashion in an attempt to accomodate research over a broad variety of important problems in CSR while maintaining a clear program-wide research focus. Further...
متن کاملOn the Hub-and-spoke Model with Arc Capacity Conatraints
In this paper, we present a new formulation of one-stop capacitated hub-and-spoke model as a natural extension of the uncapacitated one-stop model. The model involves arc capacity constraints as well as hub capacity constraints, which enables us to incorporate some practical factors into the model. We also present a branch-and-bound based exact solution method with Lagrangian relaxation boundin...
