Inoperability Input-Output Model for Interdependent Infrastructure Sectors. I: Theory and Methodology
The paper discusses the theory and methodology supporting the development of the inoperability input-output model (IIM). The IIM is based on Leontief’s input-output model, which characterizes… Expand
Homeland security preparedness: Balancing protection with resilience in emergent systems
The report of the President's Commission on Critical Infrastructure Protection [PCCIP, Executive Order 13010, The White House, Washington, DC, 1997] which was issued in October 1997 set in motion a… Expand
Development of the multiregional inoperability input-output model (MRIIM) for spatial explicitness in preparedness of interdependent regions
Any given region in the US is a complex, interconnected, and interdependent economic system of systems that includes multiple stakeholders, spans multiple sub-regions, and produces a very large… Expand
Inoperability Input-Output Model for Interdependent Infrastructure Sectors. II: Case Studies
The paper discusses case studies of the inoperability input-output model (IIM) for modeling impacts of willful attacks on interdependent sectors. The IIM is a model for assessing sector… Expand

Application of the inoperability input - output model (IIM) for systemic risk assessment and management of interdependent infrastructures
Engineering degree students are deficient in mathematical expertise—why?
The general opinion of university lecturers is that standards in mathematics have fallen substantially over recent years. There is, however, very little empirical evidence in support of this… Expand
