Twenty-Five Years of Hub Location Research
TLDR
Insight into early motivations for analyzing hub location problems are provided and linkages to problems in location analysis and network design are described to suggest promising directions for future effort.Abstract:
Last year was the 25th anniversary of two seminal transportation hub location publications, which appeared in 1986 in Transportation Science and Geographical Analysis. Though there are related hub location and network design articles that predate these works, the 1986 publications provided a key impetus for the growth of hub location as a distinct research area. This paper is not intended as a comprehensive review of hub location literature; rather, our goal is to reflect on the origins of hub location research, especially in transportation, and provide some commentary on the present status of the field. We provide insight into early motivations for analyzing hub location problems and describe linkages to problems in location analysis and network design. We also highlight some of the most recent research, discuss some shortcomings of hub location research and suggest promising directions for future effort.read more

Coordinated Logistics with a Truck and a Drone
John Gunnar Carlsson,Siyuan Song +1 more
TL;DR: It is demonstrated that the improvement in efficiency of a delivery system in which an unmanned aerial vehicle UAV provides service to customers while making return trips to a truck that is itself moving is proportional to the square root of the ratio of the speeds of the truck and the UAV.

Filling in the blanks: network structure and interbank contagion
TL;DR: In this paper, the authors propose an efficient alternative that combines information-theoretic arguments with economic incentives to produce more realistic interbank networks that preserve important characteristics of the original interbank market.

Hub Location Problems
TL;DR: This chapter overviews the key distinguishing features, assumptions and properties commonly considered in HLPs, and highlights the role location and network design decisions play in the formulation and solution of HLPs.

Optimum Locations of Switching Centers and the Absolute Centers and Medians of a Graph
TL;DR: It is shown that the optimum location of a switching center is always at a vertex of the communication network while the best location for the police station is not necessarily at an intersection.

A Quadratic Integer Program for the Location of Interacting Hub facilities
TL;DR: In this paper, a new formulation of a general hub location model as a quadratic integer program was reported, and a variety of alternative solution strategies were discussed. But the non-convexity of the objective function makes the problem difficult.
