On the development of approaches to system safety assessment in the design of technical systems

The purpose of the study is to develop analytical approaches for the comparative assessment of technical systems in the implementation of expert activities. In the course of the research, priority directions for the selection of quantitative demonstration indicators of devices and technologies, and recommendations for choosing strategies for expert work when conducting assessments of technical systems security have been identified. A factual approach has been developed for relative (rating) comparison of designed, planned or applied technologies without the use of experimental data in the absence of operational experience. New opportunities for expanding expert assessments and analysis of equipment designs and technological solutions are shown. Their novelty lies in the application of the approaches of the safeometrics developing concept and consists in the use of plausible patterns for quantitative assessment of the parameters contained in the design and technical documentation and characterizing technical systems and complexes. Data for analysis can be prepared (collected) by experts or designers based on the requirements and recommendations of experts.
