I2Sim: A matrix-partition based framework for critical infrastructure interdependencies simulation

In the recent years, there has been considerable interest in modeling and simulating interdependencies among critical infrastructures. For most cases, agent-based frameworks are employed for these types of simulation. In this paper, we have presented a new approach for interdependency simulation that we implemented in our infrastructure interdependency simulator (I2Sim). This is based on matrix partition-based technique named multi-area Thevenin equivalent (MATE). MATE model has been used for large-scale real-time power system simulation and is an efficient alternative to the existing agent-based critical infrastructure simulation frameworks. Another distinguishing feature of I2Sim is that, it is based on cell-channel model where interdependencies among different infrastructures can be represented through a formal technique that is based on the extension of Loentief input-output model. In this paper, we have presented the implementation architecture of I2Sim. We also have discussed some simulation results to show the usefulness of our approach.
