MS_228 — Risk assessment and decision support systems for interdependent lifeline infrastructures (2)

The Input-Output model comprises a linear, deterministic, equilibrium approach and a framework capable to describe the degree of interconnectedness. It can be used in national or regional level and with some restrictions in city level if economical data is available. It gives better results in large systems, if coefficients are considered to be constant for a fixed unit of time (static approach); however it should be carefully used in “close systems”.
