An improved Least Cost Heuristic for dynamic yard crane deployment in container terminals Abstract: Yard Crane (YC) deployment in a multi-berth terminal is a very complex problem. The total amount of work to the entire terminal yard changes dynamically over time. The levels of workload to different parts of the yard also vary …

terminals, a greater degree of clustering is observed as thereservation is made earlier . When considering the associated operational costs associated to yard cranes and yard trucks, greater clustering results in more efficient use of the energy, and therefore reservation may be desirable when possible to enhance terminal productivity.

The quay crane (QC) is one of the most important equipment in the container terminal because it decides the capacity of the quayside operation and berth service. A macroscopic simulation model of the quayside operation and berth service in the container terminal is proposed in this study.

This paper focuses on how to optimally route transfer cranes in a container yard during loading operations of export containers at port terminals. Decision variables are the number of containers that a transfer crane picks up at each yard-bay and the sequence of yard-bays that a transfer crane visits during a loading operation.

Global engineering company ABB and Austria-based crane manufacturer Kuenz have secured the largest single order for Automatic Stacking Cranes (ASC) ever placed by a European terminal. This order is part of the ambitious "phase 2" expansion project at APM Terminals Maasvlakte II (APMT MVII) in Rotterdam, the Netherlands.

To attract more ships and decrease operational costs, terminal operators seek methods to improve container handling efficiency without purchasing new equipment. Double cycling is one of the most widely used low-cost techniques to improve the efficiency of quay cranes (QCs) by eliminating some empty crane moves [1, 2]. With QC double …

The joint scheduling of quay cranes (QCs), yard cranes (YCs), and yard trucks (YTs) is critical to achieving good overall performance for a container terminal. However, there are only a few such integrated studies. Especially, those who have taken the vessel stowage plan (VSP) into consideration are very rare. The VSP is a plan …

Abstract: As quay cranes and RTGs are vital handling equipment at container terminals, their scheduling optimization would significantly affect the terminal's operation efficiency and costs. Most of the existing literature mainly studies a single quay crane, RTG dispatch, or the joint dispatch of handling equipment and horizontal transportation equipment, and …

Two improved Least Cost Heuristic (LCH) algorithms are proposed that consider practical operation constraints and improve performance by adding weight to long waiting jobs and judicious use of YC idle time within deployment periods. Yard Crane (YC) deployment in a multi-berth terminal is a very complex problem. The total amount of …
