Resilient control systems Practical metrics basis for defining mission impact

Abstract

Resilience" describes how systems operate at an systems. Without a significant investment by the federal acceptable level of normalcy despite disturbances or threats. In government to address this national gap in technology, this paper we first consider the cognitive, cyber-physical policies and regulations, modern control systems will remain interdependencies inherent in critical infrastructure systems and the soft underbelly for cyber-attacks, a major impediment to how resilience differs from reliability to mitigate these risks.implementing national Smart Grid, and the limiting Terminology and metrics basis are provided to integrate the cognitive, cyber-physical aspects that should be considered when technology to optimizing response to the next national defining solutions for resilience. A practical approach is taken to emergency like the Hurricane Sandy.roll this metrics basis up to system integrity and business case metrics that establish "proper operation" and "impact." A notional chemical processing plant is the use case for demonstrating how the system integrity metrics can be applied to establish performance, and as well, the effects on the process that roll into the business case.

Towards a Resilience Metric Framework for Cyber-Physical Systems

“…The framework design is based on a recent definition of resilience by Arghandeh et al (2016) and is an improvement over future work by Rieger (2014) and Eshghi et al (2015). It supports the design of a resilience metric that can evaluate a system with respect to different dimensions of performance that we call performance features.…”

“…This simplification limits the flexibility of the metric and it is therefore not possible to identify the system's shortcomings based on the metric results. The closest to a scalable and flexible metric is the work by Rieger (2014) and Eshghi et al (2015). Their metric considers the CPS domains, analogous to Arghandeh et al (2016).…”

“…Their metric considers the CPS domains, analogous to Arghandeh et al (2016). In Rieger (2014) resilience is considered with respect to control stability. The author uses control response and stability as performance measure.…”

A cyber-physical resilience metric for smart grids

“…Cyber-physical systems are comprised of three different domains that interact to provide a service [1], [7]: the physical, the cyber and the control (or cyber-physical) domain. In each domain, multiple measures of performance are present.…”

Resilience through Learning in Multi-Agent Cyber-Physical Systems

“…Making a system resilient to such events is non-trivial due to the high degree of inter-connectivity among the physical and software components, and the intricate cyber, cognitive, and human inter-dependencies (Rieger, 2014). One way to approach this problem (Rieger et al, 2009) is by decomposing it into two broad research thrusts.…”
