In this paper, an agent-based model of a socio-technical sys-tem is built by modifying the components and domain of anexisting model. This includes adapting an agent decision-making and communication model, a task workow model,and a performance model. The goal is to enable the model-ing of scenarios related to critical infrastructure system fail-ures, both those that are intentional e.g. computer securityviolations and those that are not.This scenario models the non-intentional complex systemfailure which resulted in the 2003 Northeast Blackout, fo-cusing on the people, tools, and organizations involved. Theadapted model formalizes and explains the Blackouts causes.An agent-based framework allows us to implement the modeland perform multiple iterations of the simulation. We studyfeatures of the output, and conduct experiments adjustingthe assignment of tasks to increase the systems robustnessto failure.
