Quay crane allocation is one of the most important scheduling plans in the container terminal. A large of production data is stored in the database of the terminal. This paper utilizes the method of data mining to analyze the problem of quay crane allocation by using these data. From the mining, valuable information has been gotten from the database. The paper chooses the fuzzy cmeans cluster a...

A load moment indicator (LMI) is an electronic device on heavy equipment cranes that can provide information and a warning system to operators in the event of overload during lifting process. This tool has very important role because it provides accessible operator about safe working (SWL) crane lift. Mobile have high accident potential when compared tower cranes, this mobile mobility. In paper...

This study considers a practical overhead crane control problem of designing a fuzzy control to ensure that the trolley arrives precisely at its destination; the load swing angle approaches to zero, and the energy of input and states is minimized. Furthermore, the constraints for the overhead crane operation are also considered and satisfied. Those constraints are that when the crane is moving,...

Abstract. In the context of development an autonomous tower crane, usage crane cameras to map respective workspace as basis for path planning is investigated. The goal generate up-to-date DEM input control. As construction sites are highly dynamic scenes, it crucial be able react any changes. Thus, real-time mapping with a visual SLAM solution aspired. quality important such safety critical app...

This work proposes a nodal-based evolutionary design optimization algorithm to frame structures whose edges are the Delaunay triangulation of homogeneously distributed nodes in domain. The remaining can freely sway domain except for loading and boundary nodes. As result, it extend space admissible solutions this problem reduce number variables. Then, sensitivity objective function, namely, sum ...

The quay crane scheduling problem consists of determining a sequence of unloading and loading movements for cranes assigned to a vessel, in order to minimize the vessel completion time as well as the crane idle times. Idle times originate from interferences between cranes since these roll on the same rails and a minimum safety distance must be maintained between them. The productivity of contai...
