Aerospace Instrument-Making Annotation << Back AN APPROACH TO ASSESSING THE CRITICALITY OF BUSINESS PROCESSES OF AIRCRAFT MANUFACTURING ENTERPRISES IN THE CONTEXT OBJECT CATEGORIZATION PROCEDURES CRITICAL INFORMATION INFRASTRUCTURE M.Yu. Rytov, Yu.Yu. Gromov, N.O. Musienko The process of assessing the criticality of business processes of aircraft manufacturing enterprises for the primary procedures for categorizing critical information infrastructure objects is described, which provides the executing commission with additional tools for collecting and analyzing assessments of significance indicators. The approach being developed is to combine the qualitative indicators provided by the experts of the categorization commission with quantitative indicators that are calculated according to a formalized procedure. Criticality assessment consists in a qualitative analysis and quantitative assessment of the key characteristics of a business process, formalization of the estimates obtained into calculated indicators and calculating the final values of the criticality of the business process. As part of assessing the criticality of a business process, estimates are calculated for all key characteristics of the process under study, since they can fully affect the development of events in the event of a computer incident, increasing or decreasing the level of subsequent negative consequences. These characteristics include the following indicators: the level of process automation, the impact of the business process on possible negative consequences that have arisen in the event of a computer incident, the impact of the business process on the functioning of other critical business processes, the presence of duplicate or backup systems that ensure the execution of the business process. Keywords: critical information infrastructure, aviation industry, aircraft construction, aircraft instrumentation, categorization, CII object, business process, criticality assessment.
