As more and more container terminals open up all over the world, competition for business is becoming very intense for container terminal operators. They are finding out that even to keep their existing Sea Line customers, they have to make them happy by offering higher quality service. The quality of service they can provide depends on their operating policies and the design of the terminal la...

To improve the efficiency of cargo handling with cranes it is necessary to control the crane trolley position so that the swing of the hanging load is minimized. In this paper we consider a linear parameter-varying model of the crane, where the time-varying parameter is the length of the suspending rope. We consider the set of models given by frozen values of the rope length and show how all th...

This paper puts forward an integrated optimisation model that combines two distinct problems arising in container terminals, namely the Quay Crane Assignment Problem, and the Quay Crane Scheduling Problem. The model is of the mixed-integer programming type with the objective being to minimise the tardiness of vessels. Although exact solutions can be found to the problem using Branch-and-Cut, fo...

In this paper, we examine crane scheduling for ports. This important component of port operations management is studied when the non-crossing spatial constraint, which is common to crane operations, are considered. Our objective is to minimize the latest completion time for all jobs, which is a widely used criteria in practice. We provide the proof that this problem is NP-complete and design a ...

Container terminals are designed to provide support for the continuous changes in container ships. The most common schemes used for dock management are based on discrete and continuous locations. In view of the steadily growing trend in increasing container ship size, more flexible berth allocation planning is mandatory. The consideration of continuous location in the container terminal is a go...

Planning multiple heavy lifts on heavy industrial projects has a major impact on construction sequencing, scheduling, budgeting and safety. Hence it has to be planned carefully to reduce the risk and to reduce the cost and duration of the projects. Traditional planning techniques are quite unproductive as they use iterative and trail and error techniques. This paper discusses the work done towa...

This paper deals with the problem of constructing the schedule for the operations of a group of quay cranes devoted to discharge/load a set of groups of containers from a vessel at a maritime container terminal. The schedule is constructed starting from the assignment of each individual group of containers to a quay crane under the goal of minimizing the overall vessel completion time, aka the ...
