Abstract
The paper considers a methodology that makes it possible to determine the relationship between useful, distracting and interfering information. The proposed methodology allows you to evaluate the relevance of information supplied to a specialist. The situation when a specialist, based on the information received, makes certain decisions and performs the assigned tasks is considered. The regularity of the change in the probability of performing these functions on the amount of information received and information capacity has been established. The regularity of the change in the probability of performing these functions on the amount of information received and information capacity has been established. It is shown that the equation of information dynamics is an information analogue of T. Malthus's population model. This makes it possible to use well-known methods of analysis and extend the results obtained to other mathematical models. The procedure for selecting models that take into account various restrictive effects is considered. The factor of self-limitation is taken into account. The transition to an informational analogue of the Quetelet-Verhulst population model is justified. The external limiting factor is considered in the context of the influence of distracting and disturbing information. A predictive model for determining the pattern of changes in information ability is proposed. This model takes into account the speed of information flow under ideal conditions and the destructive influence of distracting and interfering information. The procedure for using the model is reviewed. This procedure provides an introduction to the calculations additional variable to take into account the influence of distracting and interfering information. The regularity of the change in the additional value and its relationship with information capabilities have been determined. It allows you to go to the procedure for finding out the potential value of the relevance indicator. A relationship has been established to determine the relevance indicators, which make it possible to take into account the potential amount of useful, distracting and interfering information. The relationship between the current and established values of relevance indicators has been established. The classification of the effects of distracting and interfering information is carried out. Relevance characteristics for the prevailing equal and weak influence of interfering and distracting information compared to useful information are analyzed. Methodology of using the relevance characteristics is considered. The ratios that make it possible to quickly assess the relevance indicator at predetermined control points and to determine the time to reach the control values of the observed values are established. The situation that arises under very strong and very weak influences of distracting and interfering information is analyzed.
