Keywords: Container terminal Maritime shipping Block length Yard crane deployment Simulation Terminal design Gross crane rate As more and more container terminals open up all over the world, terminal operators are discovering that they must increase quay crane work rates in order to remain competitive. In this paper we present a simulation study that shows how a terminal's long-run average quay...

In this paper we focus our attention on the operational decision problems related to the seaside area of maritime container terminals. In particular, we face the Quay Crane Assignment Problem (QCAP) and Quay Crane Scheduling Problem (QCSP) with an integrated simulation-optimization approach. A 0/1 MIP model is developed in order to determine the optimal assignment, on a shift basis, of QCs to b...

This paper addresses the joint quay crane and truck scheduling problem at a container terminal, considering the coordination of the two types of equipment to reduce their idle time between performing two successive tasks. For the unidirectional flow problem with only inbound containers, in which trucks go back to quayside without carrying outbound containers, a mixed-integer linear programming ...

Most of the operational problems in container terminals are strongly interconnected. In this paper, we study the integrated berth allocation and quay crane assignment problem in seaport container terminals. We will extend the current stateof-the-art by proposing novel set partitioning models. To improve the performance of the set partitioning formulations, a number of variable reduction techniq...

Due to the dramatic increase in the world’s container traffic, the efficient management of operations in seaport container terminals has become a crucial issue. In this work, we focus on the integrated planning of the following problems faced at container terminals: berth allocation, quay crane assignment (number), and quay crane assignment (specific). First, we formulate a new binary integer l...

The main challenge for a container terminal is to maximize its throughput using limited resources subject to various operational constraints under uncertainty. Traditional methods try to achieve this through an optimized plan by solving a quay crane scheduling problem; but the plan may become obsolete or infeasible after shocks (changes in the system due to uncertainty). To respond to shocks th...
