Abstract:

This paper introduces the new concept of restoration interdependencies that exist among infrastructures in their restoration efforts after an extreme event. Restoration interdependencies occur whenever a restoration task in one infrastructure is impacted by restoration efforts in another infrastructure. This work identifies examples of observed restoration interdependencies in the restoration efforts after Hurricane Sandy as reported by major newspapers in the affected areas. A classification scheme for the observed restoration interdependencies is provided which includes five distinct classes: traditional precedence, effectiveness precedence, options precedence, time-sensitive options, and competition for resources. This work provides an overview of these different classes by providing the frequency they were observed, the infrastructures involved with the restoration interdependency, and discussing their potential impact on infrastructure restoration.

Keywords: restoration interdependencies, Hurricane Sandy, scheduling
