Criteria for the Use of Information Technology in Assessing the Quality of Critical Infrastructure by Safety Indexes

The study aims to analyse several calculation procedures of safety assessment methods. The research objective of the study is to implement an information technology solution capable of being extensively modified and freely extended with the necessary parameters and variables, depending on the needs. The research object is a safety index assessment of critical infrastructure facilities. The research subject is the modeling utilizing specific safety indices that exhibit linear dependencies. Conversely, indices featuring non-linear relationships necessitate processing through IT software. However, the model’s adaptability and versatility stemming from its classification calculation procedures allow for extensive modification and augmentation with requisite parameters and variables to address varying requirements. The paper systematizes the procedure for obtaining an integral safety index of quality from the construction of safety function matrices. The scope of practical application of the assessment model in safety research can be a universal analytical tool for managing the safety of complex systems of any level.
