Continuous berth allocation problem (BAPC) is a major optimization problem in transportation engineering. It mainly aims at minimizing the port stay time of ships by optimally scheduling ships to the berthing areas along quays while satisfying several practical constraints. Most of the previous literatures handle the BAPC by heuristics with different constraint handling strategies as it is proved...
The berth and quay crane allocation problem aims to determine the berthing times and positions of container ships in port container terminals. Solving this problem effectively improves the efficiency of seaside operations by optimally allocating berthing spaces and quay cranes to vessels. The problem is formulated as the berth allocation problem (BAP) with multiple ships and quay cranes (QCs) and...
This study investigates the quay crane allocation problem with respect to vessel assigned to a particular discrete berth at a bulk material handling port. In the proposed model,vessels at the anchorage are berthed on a First in, first out (FIFO) basis at the port, and then the quay cranes are assigned to the berth dynamically before berthing and during unloading of the vessel. To solve the model,...
Thrust allocation is an important part of the dynamic positioning system, which determining the thrust and the direction of each of the thruster devices from the control law. This paper proposes a rational and effective method of solving thrust allocation to the semi-submersible rig based on the adaptive genetic algorithm. It is realizing the global parallel operations, achieving search in a large...
In the stockpile schedule, a reasonable block allocation plan was a good foundation for the bay allocation plans, location choices for coming containers, containers turning schedule, and the shipments. This paper has built a mathematical model for block allocation plan of outward containers. The model tried to minimize the distance between the ship and the storage blocks, and avoid shipments for multiple...
A schedule reliability problem (SRP) optimization model for dynamic berth allocation in container terminal (CT) is proposed. The model focuses on the minimum average schedule missed hours of ships between the ship schedule departure time and the actual departure time to enhance the schedule reliability (SR) of ships in CT, and the quay crane allocation is considered in this model. Particle swarm optimization...
A rolling-horizon approach was proposed, which aims at the problem of berth allocation and quay crane assignment. Then a dynamic allocation model using objective programming was initially developed for berths allocation and quay crane assignment, which more closes realistic as result of basing continuum quayside. The model objective function was subject to the minimization of the total berthing location...
A bay allocation model is developed for outbound containers at container terminal based on objective programming, which aims at the problem of stack bay allocation for outbound containers. The modelpsilas objective function is subject to the minimization of the moving distance of the yard crane when bringing outbound containers into yard and loading ships. To resolve the model, a hybrid algorithm...
Under the influence of the growth in ship scale, the container ports are in a highly competitive market environment. It should view berth allocation problems in a win-win perspective for container terminal operators and shipping companies.This paper puts forward that container ships with different TEUs capacity should be given different priorities in the process of berth allocation, and the larger...
With the development of the global business and logisticspsila a container terminal (CT) system becomes more and more busy. Therefore, the available resources in the sea port get scarcer than before. In order to increase the operating efficiency of CT system, the resources planning problem has become a critical issue in the fields of operations research and logistics. In this paper, we introduce the...
