SIMULATION MODELING OF PROCESSES FOR SERVICING THE FLOW OF MESSAGES OF OPERATIONAL, REGULATORY AND REFERENCE INFORMATION BY A NODE OF THE COMPUTER NETWORK OF THE RESEARCH INSTITUTION
PIDHURSKYI Оleksandr – Сandidate of Тechnical Sciences, Аssociate Professor,
Аssociate Professor of the Department of Мodelling and Іnformation Тechnologies in
Economics, Vinnytsia National Agrarian University (e-mail paraplane@meta.ua).
PRYSIAZHNIUK Oleh Ivanovych – Ph.D. in Agricultural Sciences, Senior
Researcher, Head of the Laboratory of Mathematical Modeling and Information
Technologies at the Institute of Bioenergy Crops and Sugar Beet of National Academy of
Agrarian Sciences of Ukraine (e-mail ollpris@gmail.com).
The paper describes the results of implementation of the simulation model of service
processes developed by the author describing the total non-uniform flow of messages of the
operational, reference and routine information by the computer network node. Experiments
with the simulation model are carried out for different values of the loading factors of the
node of the computer network, as well as at different levels of priority in servicing
communications operational, reference and regulatory information. Recommendations on
the application of service priority levels for streaming messages of operational, reference
and routine information are formulated, depending on the intensity of receipt of these
messages and the duration of their service by the computer network node.
