Multilevel analytical models for investigation of the processes of solving problems with input information distortion

Multilevel analytical models for distortion accounting and means of input information control accounting with estimating the efficiency of solving problems in computing systems were considered. On the basis of the catastrophe method, functional equations were obtained, which serve as the basis for obtaining the calculated ratios and implementing analytical methods for estimating the efficiency of information processing in computing systems for various purposes. On the basis of the proposed approach, a software package was implemented, which makes it possible to carry out a multivariate analysis of various computing system’s modes of operation.
