Rail-rail transshipment yards are an emerging and more e cient alternative to traditional shunting yards. Instead of a time-consuming reshu ing of railcars via shunting hills, in these modern yards, huge gantry cranes tranship containers between di erent freight trains. As multiple cranes process the trains in parallel, it is an important operational task to avoid interferences among cranes. To...

Standardisation of crane design procedures enables designers to develop their own crane automation software for crane design applications. Since main effort and time for implementation of the crane design procedures are generally spent for interpretation and explanation of the available crane design standards, a computer-automated access to the available standards may improve speed, reliability...

This paper purports to provide answers to the following questions with regard to multi-crane building construction sites: (1) Do such construction sites differ from smaller sites only in magnitude, or are there unique characteristics that stem from the size of the site and the multitude of cranes? (2) Is equipment planning for such projects similar to that of projects serviced by a small number...

In container terminals, discharging and loading of vessels are critical planning decisions which highly depend on the interaction between the quay cranes and internal trucks, they also have a significant impact on the terminal performance and revenue. Decisions on the assignments of quay cranes and internal trucks to the berthed vessels are typically made sequentially. However, the applicabilit...

Today, tower cranes are in widespread use on construction sites all around the world. An important issue that arises when operating these cranes is the oscillatory behavior that occurs during payload transportation, which can have severe effects on safety as well as accuracy of payload delivery. Due to the nonlinear nature of the rotating crane motion, controlling these oscillations is a comple...

Crane scheduling in container terminals is known as a difficult optimization problem that has become even more challenging in recent years with the proliferation of multi-gantry automated stacking cranes. In this paper we present an efficient algorithm solving a subproblem arising in this context, namely deciding the priority of cranes after transportation tasks have been assigned. We tackle th...

The quay crane scheduling problem studied in this paper is to determine a handling sequence of holds for quay cranes assigned to a container vessel considering interference between quay cranes. This paper provides a mixed integer programming model for the considered quay crane scheduling problem that is NP-complete in nature. A genetic algorithm is proposed to obtain near optimal solutions. Com...

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...

Increasing numbers of previously threatened large grazing birds (cranes, geese and swans) are causing crop damage along their flyways worldwide. For example, the number of reported incidents of crop damage caused by common cranes Grus grus, followed by regulated inspections and governmental compensation in Sweden, has increased over the last few decades and was valued at 200,000 Euros in 2012. ...
