Підхід до математичного моделювання ефективності web-ресурсів

Abstract

Modeling of estimation processes of functioning efficiency level of information webresources is considered in the paper. The application of stochastic models with thresholds is represented. An approach to estimation of the parameters of these models is proposed. A number of experimental researches has been carried out. The researches were executed using real data of a web-resource functioning. Based on the experiments, an efficiency of the proposed approach has been approved. To estimate an efficiency of the information web-resources functioning, it is necessary to use mathematical models. These models allow to solve the tasks of software algorithms optimization and usage of technical resources. Their building requires a comprehensive research of the web-resources functioning processes taking into account the influence of all elements of a system on its functioning. The fundamental difference between the model proposed in this paper and the threshold autoregressive and time-dependent autoregressive moving average models consists primarily in the fact that the values of a modeled indicator are identified by only available parts. Therefore, instead of a time series model, models of dynamic observation systems are used. In addition, there is the possibility of multiple modes change in the evolution process of an observation system.
