Multi-Layer CPS Simulation for Critical Infrastructure Interdependencies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Critical infrastructure sectors, such as communication, energy, and transportation, are inadequately equipped to detect, analyze, and respond to disruptions that affect multiple sectors simultaneously, particularly due to the complexity of cyber-physical systems and the lack of effective simulation tools for understanding interdependencies and vulnerabilities.
Innovation Solution
A holistic, integrated simulation platform is developed to model multi-layered cyber-physical systems, incorporating electrical, communication, transportation, and other sectors, allowing for the simulation of interactions and stress scenarios like cyber-attacks and natural disasters, enabling users to identify causal relationships and vulnerabilities, and train for responses through interactive attack/defense simulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a holistic integrated simulation platform is developed to model multi-layered cyber-physical systems, then the ability to detect and analyze disruptions affecting multiple sectors is improved, but the device complexity increases
Solution Approach 1:
The simulation platform is divided into multiple independent simulation layers, each representing a different critical infrastructure sector (electrical grid, transportation, water supply, communication). Each layer can be developed, maintained, and executed independently while still contributing to the integrated multi-sector analysis capability.
Solution Approach 2:
The platform is designed as a universal simulation system that can model and analyze disruptions across multiple critical infrastructure sectors simultaneously. It provides multi-functional capabilities including disaster simulation, vulnerability assessment, interdependency analysis, and response planning for various sectors through a single integrated platform.
2Measurement precision
If multiple simulation layers representing different infrastructure sectors are integrated, then the measurement precision of interdependencies and vulnerabilities is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The platform introduces standardized interfaces and coordination mechanisms that act as intermediaries between different simulation layers. These intermediaries enable precise measurement of interdependencies by translating and coordinating data exchanges between sectors while managing the complexity of multi-sector integration.
Solution Approach 2:
The system adds a new dimension of analysis by integrating multiple sectoral simulation layers vertically, allowing simultaneous observation of disruptions across electrical, transportation, water, and communication sectors. This multi-dimensional approach enables comprehensive interdependency analysis that cannot be achieved through single-sector simulations.
3Adaptability or versatility
If the simulation platform models outlier conditions and stress scenarios, then the adaptability to realistic disruption scenarios is improved, but the device complexity increases
Solution Approach 1:
The simulation platform incorporates dynamic modeling capabilities that allow it to adapt to various disruption scenarios including natural disasters, cyber-attacks, and infrastructure failures. Each simulation layer can dynamically respond to stress scenarios and outlier conditions while maintaining system coherence through standardized interaction protocols.

AI summary
Systems and methods for simulating cyber-physical systems are disclosed. A plurality of geographic simulation layers representing respective infrastructure sectors of a real-world environment may be generated, and the layers may be linked together with one another to create a multi-layer simulation. The associations between the layers of the simulation may be adjusted, and characteristics of the simulation layers themselves may be adjusted, to ensure that the simulation conforms to characteristics of the real-world environment being simulated. In some embodiments, a multi-user simulation system allows users at separate terminals to execute attack inputs and defense inputs against the simulation to try to destabilize and stabilize the simulation, respectively. Results of the attack inputs and defense inputs may be simultaneously displayed on a plurality of terminals.
