MATHEMATICAL AND SIMULATION MODELING OF OPERATION PROCESSES IN THE CONCENTRATION NODE OF HYBRID LOGISTIC TRANSACTION FLOWS

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.
