A New Approach to Identification of Critical Elements in Railway Infrastructure

Integral approach to assessing the criticality of railway infrastructure elements

“… method for identifying and ranking critical components and sets of components in technical infrastructures (Jönsson et al, 2008)  infrastructure interdependencies simulator (i2Sim) (Alsubaie et al, 2015)  framework for assessing the vulnerability of rail freight networks by introducing two bi-level models (Bababeik et al, 2017)  procedure for identifying potential CI elements in the railway sub-sector (Leitner et al, 2017)  methodology for identifying critical infrastructure objects in transport (Dvorak et al, 2017). The above tools and methods were compared using a set of criteria reflecting defined evaluation conditions, i.e., by taking into account the key factors determining and influencing the criticality assessment of all elements of the railway infrastructure.…”

“…Although all methods deal with evaluating critical elements in railway infrastructure, the individual approaches are so different that they cannot be effectively compared to each other. For example, methods that allow integral evaluation (i.e., Jönsson et al, 2008;Alsubaie et al, 2015;Bababeik et al, 2017) only access evaluation in a networked manner and require the use of specific software tools, whereas methods allowing elementary evaluation (i.e., comprehensive evaluation of point, areal and LEs) only approach evaluation in a separate manner and thus do not take into account all factors (i.e., Leitner et al, 2017;Dvorak et al, 2017).…”

“…The results of the assessment showed that in addition to elements of critical infrastructure, some elements did not meet the defined cross-sectoral and sectoral criteria in railway infrastructure but were key or even critical to the region (Slivkova et al, 2018). These elements must be appropriately identified, and their criticality evaluated in order to adopt adequate security measures (Leitner et al, 2017).…”

“…Assessing elements in terms of railway transport renewal according to a multi-criteria analysis of the financial, economic and environmental domains is a similar approach (Caetano et al, 2018). Another specific approach is assessing the importance of a given element (i.e., performance or category) or its importance arising from the possibility of an alternate route or the likelihood of occurrence of an adverse event (Leitner et al, 2017). Another aspect not to be overlooked is identifying critical sites based on reliability analyses (Fourie and Zhuwaki, 2017), analyses of expected accident data (Striegler et al, 2012) or analyses of the vulnerability of interdependent technical infrastructures (Johansson et al, 2011).…”

Reliability of Selected Critical Infrastructure Elements

“…Research in the area of critical infrastructure is focused mainly on the risk management, as the work of Hudakova (2016), which work is pointed out of the method of risk management of operators of the elements of critical infrastructure or is focused on the process of identifying of critical infrastructure elements as Leitner et al (2017) made. Another research on critical infrastructure are focused on the measuring societal vulnerability due to failure of critical infrastructure, by Lusková et al (2018).…”
