The continuous berth allocation and quay crane assignment problem considers the size of berths ships, number cranes, dynamic ships non-crossing constraints cranes. In this work, a mixed-integer linear programming model is established, aiming at minimizing total stay time delay penalty ships. To solve model, separated into discrete segments via proposed discretization strategy. Thereafter, large...

In this paper we integrate two decision problems arising in container terminals: the berth allocation problem, which consists of assigning and scheduling incoming ships to berthing positions, and the quay crane assignment problem, which assigns to incoming ships a certain QC profile (i.e. number of quay cranes per working shift). They are indeed strictly correlated, as the QC profile assigned t...

In the last few years, the remarkable increase of containerized trade and the resulting increase in congestion and operating costs of container terminals have indicated the importance of integrated management of port resources. This research investigates an integrated decision problem that deals with the simultaneous optimization of berth allocation, tugboat and quay crane assignment. The main ...

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...

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 ...

Input-shaping is a practical open-loop strategy for the control of transient and residual oscillations on cranes, especially those having predefined payload transfer paths and repeated maneuvers. In this paper double-step input-shaping control approach is developed to include maneuvers that involve large hoisting distances and speeds. The approach is based on using the graphical representation ...

A solution to the problems of resource allocation and scheduling of loading and unloading operations in a container terminal is presented. The two problems are formulated and solved hierarchically. First, the solution of the resource allocation problem returns, over a number of work shifts, a set of quay cranes used to load and unload containers from the moored ships and the set of yard cranes ...

Vessel discharge and load jobs in a container terminal can be divided into sequences, one for each assigned quay crane (QC). A QC sequence lists containers in their desired handling order. The common practice for operators is to make do with just this sequence, without generating a job schedule (i.e. desired start-times of handling each container). Operators who need job schedules generate crud...

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 double 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 integrated with a detailed model of the container stack. The result is a ge...
