对关键基础设施(更名为CI)的中断或故障的研究，是对(A)关键基础设施系统(更进一步称为独联体)中的现象进行调查的一个重要领域。对问题强度及其影响扩散模式的预测所产生的结果，是有关各方为尽早和有效地实现安全和安保措施而进行的任何决策过程的重要组成部分。因此，本文的目的是评估CI系统中的级联效应。文章的第一部分讨论了影响的类型--形成其性质的方面；以及这些影响在竞争情报结构中的传播方式。此外，还描述了目前评估这种连锁影响的方法。基于这些事实，作者定义了在CI系统中评估连锁影响的原则和框架。用于量化级联影响在独联体中的扩散的CIA方法(级联影响评估-更名为CIA)是本文最重要的部分。这一方法的实质在于它评估了在选定地区发生的所有行业，并评估了这些行业的复原力和联系；随后，创建了连锁影响扩散风险的结构图。(C)2018爱思唯尔B.V.保留所有权利。
Research into disruptions to, or failures in, the Critical Infrastructure (further only CI), represents an important area of investigations into the phenomena in (a) Critical Infrastructure System (further only CIS). The results arising from the prediction of the intensity of problems - and the line(s) of their impacts spread-patterns, are an important part of any decision-making process carried out by the involved parties for the early and effective realization of Safety and Security Measures. Therefore, this article's aim is to assess cascading effects in a CI system. The first part of the article deals with the typology of impacts - the aspects that form their nature; and the ways these impacts spread in a CI structure. Furthermore, the current approaches to the assessment of such cascading impacts are also described. Based on these facts, the authors define the principles and framework for assessing cascading impacts in a CI system. The CIA Method (Cascading Impact Assessment - further only CIA), which serves for the quantification of the spread of cascading impacts in a CIS, is the most important part of this article. The essence of this method lies in its assessment of all lines of business occurring in the chosen area, as well as an assessment of their resilience and links; subsequent to this, a structural map of the risk of the spread of cascading impacts was created.
