Annotation

The paper describes the results of mathematical and simulation modeling of the

concentration (distribution) transaction node in the logistic system formalized by the queue

system. The author developed a number of the system models, with transaction flows on the

input, generated on the base of traditional and alternative methods. The mentioned models

describe processes of formation and maintenance of the hybrid flow of material (inmaterial)

logistics objects. In order to verify and validate the models, a comparative analysis of the

results obtained during the experiments was carried out. The analysis resulted in a

grounded conclusion about the mutual correspondence of numerical characteristics of

models as well as introduced the alternative generation method for the transaction input

flow in the imitating modeling of queue systems.

This work is based on materials obtained by the author in the previous studies.

Keywords: mass service system, transaction flows, mathematical model, simulation model, verification, validation.
