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).


In the article the two simulation models of heterogeneous hybrid transaction flow 

that is the result of a superposition of uniform and Poisson flows have been created and 

tested. The first model simulates the generation process of two independent transaction 

streams (uniform and Poisson) and their subsequent superposition. The second simulation 

model is based on the superposition mathematical model of both uniform and Poisson 

transaction flows. On the basis of the mathematical model a random number generator has 

been built, which directly determines the  time intervals between the transactions of the 

hybrid flow. The results of experiments for mathematical and simulation models of the 

hybrid stream have been analyzed as well as the adequacy of these models has been 

estimated.  The current work is the continuation of the previous research of the author.

Keywords: transaction flows, superposition of flows, simulation models, mathematical models, probability distribution, adequacy of models.
