Commercial air transport in rural and remote areas of the United States has a long history. After the Airline Deregulation Act of 1978, carriers were free to serve any cities and routes they wished. In anticipation of carriers gravitating toward large urban markets, the Essential Air Service...

A common theme in analysis and evaluation of network-based critical infrastructure is the assessment of system vulnerability. Graph theoretic, simulation, and optimization-based techniques have played a significant role in examining potential network vulnerabilities given the insights they can...

Digital subscriber lines (xDSL) belong to a family of technologies that provide the ability to transmit digital data over local telephone (copper) infrastructure. As the second most popular broadband platform in the United States, it is estimated that over twenty-five million xDSL lines are in...

Evaluating network infrastructures for potential vulnerabilities is an important component of strategic planning, particularly in the context of managing and mitigating service disruptions. Many methods have been proposed to facilitate such analysis, providing different interpretations of...

This Handbook offers an unrivalled overview of current research into how globalization is affecting the external relations and internal structures of major cities in the world.

The US federal Essential Air Service program was established to subsidize air service to communities unable to retain commercial carriers after airline deregulation in 1978. In this paper, the subsidized service between program communities and commercial hub airports is investigated relative to...

Siting facilities in continuous space such that continuously distributed demand within a region is optimally served is a challenging location problem. This problem is further complicated by the non-convexity of regions typically encountered in practice. In this paper a model for maximizing the...
