<p><span lang="PT-BR">PT Jakarta International Container Terminal (JICT) is the largest container port in Indonesia. Currently, JICT capacity 2.5 million TEUs (Twenty-foot Equivalent Units) per year, it continues to strive improve international services and supported by adequate loading unloading equipment. The requirement establish common standards different types of equipment iden...

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...

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 ...

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...

In this paper, Gain-Scheduling (GS) control via parameter dependent Lyapunov function for crane is synthesized. A purpose of cranes system is to lift and carry a load to assigned positions. Cranes are required to transport the load fast, accurately and to reduce oscillations. In previous research, a method to robust control of cranes to suppress effects by variation of the rope length have been...

The stability of the quay wall incorporating large diameter cylinders is of great concern at the Yangshan Port, China, owing to severe marine environment. In this study, finite element analysis is carried out to evaluate the stability of a trial quay wall during construction. The single cylinder is examined in terms of turnover failure subjected to a five year design wave action. The case when ...
