A Georgia Tech inventor has developed PRIISM; (Probabilistic Resilient Interdependent Infrastructure System Modeling) a software that conducts comprehensive system modeling that includes the complex relationships between components in multiple connected infrastructure systems. This includes dependencies between systems, geographic interdependencies, and repair interdependencies. Repair interdependencies is where repairing or recovering one component in a system is dependent on a component from another connected system that provides access to the damaged component. These capabilities allow PRIISM to assess and predict infrastructure system performance and account for hazardous events such as cascading failures.
- Accounts for system inter-dependencies in modeling
- A cost effective way to manage system assessment and risk
- Minimizes impact of system disruptions in an interconnected architecture
- Infrastructure network systems
Existing infrastructure system risk modeling methods focus on single systems, providing assessments of risk within a single infrastructure network type. These modeling and analysis technologies look specifically at a single infrastructure system. Information inputs to infrastructure risk assessment software programs include component characteristics such as location, material, age, size, and maintenance record. Existing methods only focus on single systems, leaving them unprepared for the interconnectedness of modern infrastructure systems and the risks and vulnerabilities created by dependencies of systems on one another.
