Leontief-Based Simulation Tool
Print

The Leontief-Based Simulation (LBS) Tool s a simulation tool for studying the interdependencies of critical infrastructures. The critical infrastructures are represented as nodes of a network and their interconnections are represented as arcs of that network. The tool is based on the Leontief Input-Output Model where the inoperability of the system of systems is analysed. The dependency of the sub-networks on one another is expressed through Leontief technical coefficients showing to what extent each system needs the goods and services of the others. The LBS tool displays in graphical form the propagation of disturbances among the subsystems, indicating the points where some measures can be taken to turn the network back to equilibrium.
