The objects of research - the process of protecting information and information resources, the process of diagnosing units of aviation gas turbine engines, the process of investment management, risk-based. The work improved method for calculating matrix elements Hasse-Witt for hipereliptychnyh special type of curves of arbitrary genus. A rapid method improved scalar multiplication on elliptic curves and hipereliptychnyh of prediction. A method of reducing the influence of boundary effects on the results of wavelet transform. Developed an improved method of analyzing high-frequency envelope of a random vibration. Based on the developed method has become a model for further development of diagnostics units of GTE, which allows to detect wear of parts at an earlier stage. Methods of forecasting failure risk of investing in non-financial assets and the actual results of the deviation from the planned investment and support model of decision making in the management of investments that create information technology investment management.
