Abstract
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.
Highlights
There are many scientific papers regarding hub and spoke systems in maritime container shipping
Trunk and feeder network design problems were suggested to be solved by methods like: variable neighborhood search [6], genetic algorithm-based heuristic [7], liner programming, using simplex algorithm [8], mixed integer liner programming [9,10]
Feeder container lines are not a separate system; they are in close interaction with the environment - a system of trunk container lines

Hub ports are considered to be the boundary of the system and the external environment. Mathematical models were simulated for the two levels. Container flows are determined (based on statistical data), which enter and exit the hub. 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.
