The container crane is a key machine in ports. Over the past 15 years, modeling and control of quay cranes for automating ports has been the main research issue. In this paper, crane models and control methodologies appeared in the literature are reviewed. A generalized formulation of the most widely used crane model is introduced. Various control techniques are briefly discussed. In conclusion...

In automated container terminals, containers are transported between ships and storage yard by differen types of vehicles, for example, guided vehicle (AGV, yard crane (YC) and quay crane (QC). To improve the productivity of the automated container terminals, it is important to harmoniously synchronize operations of different types of container handling equipment. This paper examines the schedu...

This paper discusses the problem of scheduling quay cranes, the most important equipment in port terminals. A simulation model is developed for evaluating time of quay cranes. Then a dynamic scheduling model using objective programming for quay cranes is developed based on genetic algorithm approach. Finally, numerical experiments on a specific container terminal are made for propose approach. ...

This section provides detailed results for all sets of benchmark instances introduced by Meisel [1]. The notations of problems characteristics are the same as ones used in Meisel [1]. Loc indicates the distributions of tasks on the vessel, f indicates the the handling rate, d is the precedence density, q is the number of QCs, and s is the safety distance. The signs ∗ and ▲ respectively indicate...

Container terminals mainly include three types of handling equipment, i.e., quay cranes (QCs), internal trucks (ITs) and yard cranes (YCs). Due to high cost of the handling equipment, container terminals can hardly purchase additional handling equipment. Therefore, the reasonable scheduling of these handling equipment, especially coordinated scheduling of the three types of handling equipment, ...

The scheduling problem is one of the most important operation in maritime ports. In this study we solved for a single quay crane and multiple yard trucks port Tripoli-Lebanon. previous proposed two exact methods but faced large instances CPU time. For reason, paper developed heuristic method (genetic algorithm) to obtain near optimal solution with an acceptable main objective minimize completio...

Motivated by the call of International Maritime Organization to meet emission targets 2030, this study considers two important practical aspects quay crane scheduling: efficiency and energy consumption. More precisely, we introduce bi-objective scheduling problem where objective is minimize vessel’s completion time crane’s This done formulating a mixed-integer programming model. A branch-and-bo...

Abstract Quay cranes are among the most important resources in port terminals, and their efficient use is crucial for terminals to remain competitive market. The problem of determining sequence tasks performed by quay that minimizes turnaround time a vessel an NP‐hard known as crane scheduling (QCSP). In this paper, we consider unidirectional QCSP under uncertain processing times, where only al...
