Determinants of cargo flow modeling in container terminals in conditions of „extended pre–gate”

The paper considers determinants of construction of the mathematical model describing in a macro scale a stream of cargo, flowing through a container terminal equipped with an extended pre-gate. Accordingly, the work analyzes the handling points and channels of container’s flows at a hypothetical terminal, as well as opportunities allowing to increase the flow’s efficiency by changing the random stream of arriving trucks and trains into the determined one.
