Balashova K.V., Semenova E.G., Smirnova M.S., Ivakin Ya.A.  Key approaches of risk management to the detection, assessment, hedging, and localization, of dataware quality deterioration risks

The development of state-of-the-art advanced tools for supporting science-intensive production is an expensive and resource-demanding process. The paper substantiates the relevance of developing scientific tools for complex assessment, hedging, and localization of risks associated with the deterioration of dataware of training systems for control room operators because of the integration of interactive electronic manuals. The functional model of qualitative risk assessment is presented in the numerical form be means of soft computing. Qualitative risks are transferred into quantitative ones by appropriate scaling of possible change ranges of the values of these estimates. Color differentiation of risk levels in digital risk assessment matrices is implemented.
