Vector model of the engineering infrastructure risk

Abstract

The subject of the article is the concept of a vector risk model and its application in the process of risk estimation and evaluation in relation to the basic features of the utility of engineering infrastructure. This model, with the help of dimensions such as e.g.: functionality (F), reliability (N), safety (B), continuity of operation (C), etc. as well as parameters concerning conditions and operating environment (E) takes into account the set of potential hazards to engineering infrastructure and a set of risk factors resulting both from the structure of the engineering infrastructure itself and its environment. This model allows for easy selection or development of the method of risk estimation and management, which in turn may be the basis for determining the current level of the usefulness of engineering infrastructure and the risk of its loss. The value of IT risk is determined using synthetic indicators expressed in the form of conventional potentials calculated on the basis of parameters and indices of basic engineering infrastructure elements. The model determined this way also allows, among others, for: continuous control of selected operational indicators of the basic elements of engineering infrastructure (for early detection of hazard, hazard and vulnerability analysis, risk assessment and evaluation related to individual features of engineering infrastructure), monitoring of infrastructure risk level and its changes to the music of introducing innovativeness and modern technological solutions to it, e.g. information technology solutions.
