Key Findings

01A frequency-based assignment model, adapted from transit assignment, can effectively represent full and empty container flows at a global level.
02Service frequency and port capacity significantly influence the patterns of full and empty container flows and, consequently, port choice.
03Minimizing expected cost, rather than just travel time, provides a more realistic optimization objective for container liner shipping.
