RT Journal Article SR Electronic A1 Drozhzhyn, Oleksii A1 Koskina, Yuliia T1 The Model of Container Feeder Line Organization Focused on the Nature and Parameters of External Container Flows JF Communications - Scientific Letters of the University of Zilina YR 2021 VO 23 IS 2 SP A94 OP A102 DO 10.26552/com.C.2021.2.A94-A102 UL https://komunikacie.uniza.sk/artkey/csl-202102-0018.php AB This article considers the trunk lines, connected with the feeder region as the external environment for the system - feeder lines (its subsystems are container flows, ports and container ships). Hub ports are considered to be the boundary of the system and the external environment. Thus, mathematical models were simulated for the two levels. At the first level, container flows are determined (based on statistical data), which enter and exit the hub. At the second level, the mathematical model allows to find for the feeder line: volumes of container flows, the total capacity of the ships which serves the cargo, and parts of the distribution of this capacity between feeder ports.
