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.

Keywords: information flows, mass service system, priority of service, probability distribution laws, simulation model.
