критерій ефективності

Aim. The purpose is to form a generalized performance indicator and analysis of resonant vibration machines, taking into account their main energy, dynamic and technological characteristics. Method. Three basic parameters the ratio of the maximum acceleration of the working mass to the power consumption, the coefficient of asymmetry of acceleration and the width of the resonance zone were used to evaluate the efficiency of vibration systems. These indicators are reduced to a dimensionless form in the next step.

Current situation of efficiency evaluation of security components of computer systems and networks is analyzed. It is founded that mentioned in the article effectiveness assessment methods are not sufficiently provided with fundamental theory and methodology and to great extent are subjective. Usage of generalized efficiency evaluation criterion is proposed. Methodology of usage of such criterion on the test case with block ciphers is overviewed.
