The quay crane scheduling problem studied in this paper is to determine a handling sequence of holds for quay cranes assigned to a container vessel considering interference between quay cranes. This paper provides a mixed integer programming model for the considered quay crane scheduling problem that is NP-complete in nature. A genetic algorithm is proposed to obtain near optimal solutions. Com...

Quay crane allocation is one of the most important scheduling plans in the container terminal. A large of production data is stored in the database of the terminal. This paper utilizes the method of data mining to analyze the problem of quay crane allocation by using these data. From the mining, valuable information has been gotten from the database. The paper chooses the fuzzy cmeans cluster a...

Nowadays, there is much attention for planning of container terminals in the global trade centers. The high cost of quay cranes motivates both scholars and industrial practitioners especially in the last decade to develop novel optimization models to address this dilemma. This study proposes a coordinated optimization model to cover both Quay Crane Scheduling Problem (QCSP) and Quay Crane Assig...

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...

This paper elaborates the different operations research methods used to solve container terminal operational decisions including terminal design, berth allocation, quay crane assignment, quay crane scheduling, container storage space allocation, container location assignment, retrieval, and premarshalling, as well as resource scheduling and terminal logistics in general. Solution methods includ...

We focus on the integrated seaside operations in container terminals, namely the integration of berth allocation, quay crane assignment and quay crane scheduling problems. We first develope a mixed-integer linear programming formulation. Then, we propose an efficient cutting plane algorithm based on a decomposition scheme. Our approach deals with berthing positions of the vessels and their assi...

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 quay crane scheduling problem consists of determining a sequence of unloading and loading movements for cranes assigned to a vessel, in order to minimize the vessel completion time as well as the crane idle times. Idle times originate from interferences between cranes since these roll on the same rails and a minimum safety distance must be maintained between them. The productivity of contai...

This paper deals with the problem of constructing the schedule for the operations of a group of quay cranes devoted to discharge/load a set of groups of containers from a vessel at a maritime container terminal. The schedule is constructed starting from the assignment of each individual group of containers to a quay crane under the goal of minimizing the overall vessel completion time, aka the ...
