This report describes wharf crane operations at container ports. In particular, it explores econometric models of wharf crane productivity, as well as simulation and analytical models that focus on the queuing phenomenon at the wharf crane. The econometric model revealed factors that significantly affect wharf crane productivity, while all other models, based on extensive time-motion studies, revealed that assumptions of exponential service times are not always appropriate. Time distributions were also investigated for the arrival and backcycle processes at the wharf crane. All findings were incorporated into simulation and mathematical queuing models for the loading and unloading of container ships.
