Assessment of the Individual Risk of Injury to Service Personnel During the Operation of Complex Technical Systems Using a Simulation Model

In a typical system for ensuring the safety of operation of equipment of complex technical systems, the most important element is the assessment of the individual risk of death (injury) and/or harm to the health of service personnel.. T erefore, in the process of developing a qualitative decision on the formation of a list and parameters of safety program measures, it is necessary to assess individual risk indicators, which is complicated by the presence of various uncertainties that cause the appearance of individual risk during the operation of equipment. T e article presents a simulation model that allows assessing the indicators of individual risk of death (injury) of service personnel during the operation of equipment in order to form a safety program. T is simulation model dif ers from the existing ones in that, as a result of aggregation of models of subprocesses of the operation of a hazardous production facility, it is possible to establish a relationship between the scenarios of the implementation of negative events, the parameters of the safety program measures and the complex ef ects of all signif cant undesirable factors. T e developed simulation model makes it possible to increase the adequacy of the assessment of the risk indicator: the individual risk of death (injury) and/or harm to the health of service personnel. T e ef iiency of the methodology will be demonstrated by the example of receiving an electrical injury by maintenance personnel during operation of the power supply system.
