P-Graph Approach to Allocation of Inoperability in Urban Infrastructure Systems
2015
Chemical Engineering Transactions
Inoperability input-output modeling (IIM) was introduced as a methodology for determining ripple effects propagating through interdependent infrastructure systems as a result of disruptive events such as natural disasters. It is based on the dimensionless metric of inoperability which indicates degree of failure along a scale ranging from 0 to 1. Previous approaches have focused on calibration of interdependencies based on records of economic statistics; IIM has also been used mainly for
