Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Assessment of the Criticality of Business Processes of Aircraft Manufacturing Enterprises When Categorizing Objects of Critical Information Infrastructure YU.YU. GROMOV, M.YU. RYTOV, N.O. MUSIENKO The modernized process of assessing the criticality of business processes of aircraft manufacturing enterprises for primary categorization procedures of critical information infrastructure objects is described, which provides the executing commission with additional tools for collecting and analyzing estimates of significance indicators. The approach being developed consists in combining qualitative indicators, which are given by experts of the categorization commission, with quantitative criteria, which are calculated according to a formalized procedure. The criticality assessment consists in qualitative analysis and quantitative assessment of the key characteristics of the business process, formalization of the obtained estimates into calculated indicators and calculation of the final values of the criticality of the business process. As part of the assessment of the criticality of the business process, estimates are calculated for all key characteristics of the process under study, since they can fully influence the development of events in the event of a computer incident, increasing or decreasing. Keywords: Critical information infrastructure, aviation industry, aircraft engineering, aviation instrumentation, categorization, CII object, business process, criticality assessment.
