The paper deals with the selected aspects of vulnerability assessment of systems. Historically, the vulnerability is recognised as one of the important aspects of system properties – system quality. The wide utilization of vulnerability can be observed in the IT area. Some approaches to vulnerability assessment are based on experiences and empiricism. For some other works it is necessary to have a quantitative value used for expressing vulnerability. In this paper we have applied the methods of analytical research, information search and a synthesis. They serve to introduce selected approaches expressing system vulnerability. The attention is paid mainly to the environmental and critical infrastructure systems. The results are presented in the form of definitions, equations or graphs. All these alternatives are further usable for assessing critical infrastructure elements. The results are also suitable for deeper development of a safety research scientific discipline.
The paper presents selected aspects of an innovatory approach to formalization of a notation of Polish Logistics System regarding transport co-modality issue. The importance of external transport in logistics process implemented by Polish Logistics System was discussed. The preliminary identification of Polish Logistics System model elements and links between them were made. As a result the formalization of notation of Polish Logistics System structure was proposed.
The aim of this article is to present and investigate the main concepts of supply chain vulnerability and resilience.
