Impacts of Port Productivity and Service Level on Liner Shipping Operating Cost and Schedule Reliability

Operating costs and schedule reliability are the two major concerns of container liner shipping operations. Port congestion and port productivity below expectations are among the main causes of schedule unreliability in the liner shipping industry, and they also result in higher operating costs of shipping lines. So far, little research has been conducted to quantify the impacts of port productivity and service level on liner shipping operating costs and schedule reliability. The problem is difficult because liner shipping operations involve many uncertainty time factors and relationships between these factors often lack closed-form expressions. This research builds a discrete event simulation model for quantitative analyses. Port productivity is measured by the number of moves per hour during a vessel’s berth time window. Port service level is measured by the percentage of “berth-on-arrival” for the service of arriving vessels. The simulation model incorporates bunker cost functions and three major time components, namely sailing time, port time and buffer time. Extensive simulation experiments with an Asia-Europe route show the significant effects of port productivity and service level on liner shipping operating cost and schedule reliability.
