Quay Cranes and Yard Trucks Scheduling Problem at Container Terminals
A bi-objective mathematical model is developed to simultaneously consider the quay crane and yard truck scheduling problems at container terminals. Main real-world assumptions, such as quay cranes with non-crossing constraints, quay cranes’ safety margins and precedence constraints are considered in this model. This integrated approach leads to better efficiency and productivity at container te...
متن کاملMultiple quay cranes scheduling for double cycling in container terminals
Double cycling is an efficient tool to increase the efficiency of quay crane (QC) in container terminals. In this paper, an optimization model for double cycling is developed to optimize the operation sequence of multiple QCs. The objective is to minimize the makespan of the ship handling operation considering the ship balance constraint. To solve the model, an algorithm based on Lagrangian rel...
متن کاملMaximizing the number of dual-cycle operations of quay cranes in container terminals
An important objective of all schedules in a port is to minimize turnaround time of vessels. An operation schedule for Quay Cranes (QCs) can significantly affect the turnaround time of a vessel. Recently dual cycling techniques have already been used for reducing the number of operation cycles of QCs in some advanced container terminals. This study attempts to minimize the number of operation c...
متن کاملImproving Quay Transport on Automated Container Terminals
In order to accommodate the growth in intercontinental container transport, port facilities have to be up-scaled drastically. One of the major challenges is to increase the capacity of the marine operation on a container terminal. In this study the model of a quay transport system using automated guided vehicles (AGVs) is used to deduce logistic principles for the design of a terminal layout an...
متن کاملA Quay Crane Scheduling Model in Container Terminals
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. ...
