In this work, we focus on the integrated planning of the following problems faced within the context of seaside operations at container terminals: berth allocation, quay crane assignment, and quay crane scheduling. First, we formulate a new binary integer linear program for the integrated solution of the berth allocation and quay crane assignment problems called BACAP. Then we extend it by inco...

This report compares the performance of three double-cycling algorithms used to determine the sequence with which to load and unload containers from a vessel with a quay crane. Double cycling is a technique which can improve the efficiency of a quay crane and container port by unloading and loading containers in the same crane cycle. The three algorithms, the greedy strategy, the proximal strat...

This paper presents a novel, mixed-integer programming (MIP) model for the quay crane (QC) scheduling and assignment problem, namely QCSAP, in a container port (terminal). Obtaining an optimal solution for this type of complex, large-sized problem in reasonable computational time by using traditional approaches and optimization tools is extremely difficult. This paper, thus, proposes a genetic ...

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...

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...

The key to improve the container terminal efficiency is the integrated optimization of the quay crane (QC) and the yard truck (YT) scheduling, which is normally settled separately and considered in a certain condition in classical literatures. To improve the operation efficiency and simulate the practical operation, a PSO-based integrated QC-YT scheduling optimization model with uncertain facto...

We present a dynamical modeling of integrated (end-to-end) container terminal operations using finite state machine (FSM) framework where each is represented by discrete-event system (DES) formulation. The hybrid model incorporates the quay cranes (QC), internal trucks (IT), and yard (YC) also selection storage positions in (CY) vessel bays. QC YC are connected IT our models. As opposed to comm...

This work addresses the Quay Crane Scheduling Problem under availability constraints, whose main goal is to determine the work schedules of the quay cranes allocated to a container vessel in order to carry out its transhipment operations (loading and unloading operations). An Estimation of Distribution Algorithm with shaking procedure is proposed to solve it. The position of the tasks and the o...

This paper considers the integrated problem of quay crane assignment, quay crane scheduling, yard location assignment, and vehicle dispatching operations at a container terminal. The main objective is to minimize vessel turnover times and maximize the terminal throughput, which are key economic drivers in terminal operations. Due to their computational complexities, these problems are not optim...
