Details

The tutorial was developed for conducting classes in the discipline "Development of emergency plans" using the SC ARBITR. The discipline is studied during the implementation of the main educational program 20.04.01_12 "Emergency preparedness and response" (international educational program) in the direction of training (specialty) 20.04.01 "Technospheric safety". The main tasks in the field of industrial safety at the present stage of development are: - introduction of a risk-based approach when organizing activities in the field of industrial safety; - development of methods for analyzing and assessing the risks of accidents at industrial facilities; - development and implementation of information technologies that allow solving complex problems of quantitative and qualitative risk analysis. Considering risk as a combination of the probability of an event causing harm and the severity of this harm, this tutorial focuses on the study of methods for assessing the probability of a hazardous event. When analyzing the hazards associated with failures of technical devices, leak detection systems, industrial automation and control systems (IACS), and safety instrumental systems (SIS), it is recommended to analyze the technical risk, the indicators of which are determined by the appropriate methods of reliability theory. At the same time, methods for calculating the reliability of technical systems are recommended to be combined with methods for modeling accidents and quantitative assessment of the risk of accidents. Among the many risk analysis methods used in practice, such methods as the analysis of reliability block diagrams, fault trees and event trees are singled out. In the course of performing practical tasks, students acquire practical skills in working in the software ARBITR. SC ARBITR is a program certified by the regulator Rostekhnadzor for solving the problems of analyzing the reliability and safety of complex technical devices at hazardous production facilities, including nuclear facilities. SC ARBITR is domestic software that implements a logical-probabilistic method based on the use of the mathematical apparatus of Boolean algebra and probability theory.
