National Critical Infrastructure Modeling and Analysis Based on Complex System Theory

Abstract

National critical infrastructure is a typical complex system with the characteristics of self-organized criticality. In this paper, we firstly analyze the basic concepts of national critical infrastructure and the associated complex system characteristics, and then construct the model of national critical infrastructure based on complex system theory. This model abstracts the nodes of national critical infrastructure network and their connectivity relationships, and supports the measurements of national critical infrastructure's attributes, therefore reflects the dynamics of national critical infrastructure. The occurrence and propagation mechanism of national critical infrastructure's cascade failure behavior is analyzed based on this model, which preliminary validates effectiveness of the proposed model.

Resilience in Complex Systems: An Agent‐Based Approach

“…Principles of network theory and network analysis are used to represent CIS as capacitated networks [Kroshl, ]. Complexity theory is applied to characterize the interdependencies and nonlinear interactions between elements of the network, the system environment, and the humans who act to operate and restore the network after a disruption [Chunlei, Lan, and Yiqi, ]. We demonstrate that ABM, and the NetLogo tool specifically [Babiš and Magula, ], can consider dynamic system interdependencies such as human interactions necessary to restore the network in an efficient manner, and is capable of modeling complex network behavior and quantifying metrics of resilience.…”

Challenges of Coordination in Provision of Urban Infrastructure for New Residential Areas: The Iranian Experience

“…To wit, what occurs to one urban infrastructure can directly and indirectly influence other urban infrastructures. Chunlei et al (2011), in parallel with this notion, point out that infrastructure systems are not only with huge scale, but also interconnected with each other. A sectoral stoppage of one urban infrastructure could result in a cascading failure for multiple interdependent infrastructures and trigger huge impact.…”

“…As such, forecasting the future needs of each of urban infrastructures by pertinent planners. In addition to above mentioned complexity characteristics of the infrastructure, Chunlei et al (2011) numerate some more characteristics for urban infrastructure as a large-scale complex system: (1) Multi-level, infrastructure cover all aspects of social life, involving energy, potable water, power, transportation, etc. Moreover, each facility can be divided into subsystems; (2) Openness.…”

Support for Managing the Survivability of Energy Systems Based on a Combinatorial Approach

“…The application of the theory of complex networks underlies the topological methods for studying critical infrastructures [8,9]. When analyzing large geographically distributed systems, such as an ES, this theory is often used to study their behavior under deliberate influences or accidental failures, including in the case of the cascading nature of the development of disturbances [10].…”
