Empirical studies on yard operations Part 2: Quantifying unproductive moves undertaken in quay transfer operations

The impact of higher container stacking on yard operations has been treated as one of the major factors influencing the efficiency of terminal operations. For terminal operators who have to increase their storage capacity by way of higher container stacking, the consequences must be carefully measured. This paper examines the unproductive container movements undertaken in one high throughput terminal with high land productivity, and provides an example of how terminal operator handles the yard operations and the possible impact on areas of operation.
