Resilience Assessment

Resilience is the ability of an object to retain its basic functions in the case of adverse events from an external or internal environment. Adverse events can jeopardize the operation of an object or cause it to become completely inoperable. The assessment of static resilience should be dealt with mainly by objects that are included in local, regional, national, and international critical infrastructure. ritical infrastructure is the basis of today's modern functioning society. The paper is focused on design of the static resilience evaluation of objects in the rail transport. The proposed method of static resilience assessment is based on safety pillars and is applied in a case study to a specific object of the rail transport. This approach is original in the conditions of the Slovak Republic.

Resilience Assessment

The article discusses the possible impact of disasters on functionality of the transport critical infrastructure elements by overcoming their resilience. The aim of the article is to provide an appropriate approach to the resilience measurement through understanding of this close relationship. It was achieved by using combination of (1) a decisiontheoretical approach based on Influence Diagrams, which was used as a tool to model functionality disruption level of transportation network elements after disaster impact and (2) the time decomposition of the functionality disruption duration of these elements. Based on this approach, the transportation network element resilience assessment was conducted in form of the transportation element resilience loss. The proposed approach is intended to be applied to the critical infrastructure elements rather than to the transportation network as a whole.
