Cross-docking is a warehousing strategy in logistics used by process industries making products with high proportions of distribution costs. It is described as the process of moving goods from suppliers to customers through a cross-dock terminal without a long-term storage in this facility. The vehicle routing problem with cross-docking (VRPCD) consists of fulfilling a set of transportation req...

Total or shared autonomous behavior is still an open challenge for service robots. An example of such system is FRIEND (Functional robot arm with user-friendly interface for Disabled people) (Figure 1). In the project ReIntegraRob care robot FRIEND will carry out all necessary manipulations for a completely paralyzed person who with support of FRIEND will be able to work in library. The task of...

Abstract We investigate a specific truck scheduling problem at cross-docks in the postal service industry on an operational level aiming to maximise number of duly parcels assuming fixed departure times outbound trucks. The inbound gates and conveyors as means transportation inside hub constitute bottleneck resources. As novel extension, we propose flexible unloading speeds efficiently utilise ...

The efficient and safe movement of freight is one of the important goals of urban transportation systems and vital to not only the local economy, but nationally as well. Given the importance of the freight transportation system, opportunities to utilize state of the art Intelligent Transportation Systems (ITS) technologies are increasing to improve the operation of the existing infrastructure t...

Getting military aircraft airborne is a symphony of planning. From the aircrew to the fuel truck driver, the coordination of effort is a complex logistical problem. In the operations world, we tend to use magnetic boards with pucks and markers to evaluate our daily resources and develop solutions to meet requirements. While there are electronic systems available, there are none that have suffic...

the paper investigates into the vibrational characteristics of the truck chassis including the natural frequencies and mode shapes. truck chassis forms the structural backbone of a commercial vehicle. when the truck travels along the road, the truck chassis is excited by dynamic forces caused by the road roughness, engine, transmission and more. modal analysis using finite element method (fem) ...

Drones are currently seen as a viable way of improving the distribution parcels in urban and rural environments, while working coordination with traditional vehicles, such trucks. In this paper, we consider parallel drone scheduling traveling salesman problem, where set customers requiring delivery is split between truck fleet drones, aim minimizing total time required to serve all customers. W...

The objective of multi-site scheduling is to support the scheduling activities of a global scheduler and schedulers in distributed production plants in a cooperative way. A global schedule generated on a global level must be translated into detailed schedules as part of the local scheduling process. In case of disturbance, feedback between the local and global levels is essential. Previous meth...

<p style='text-indent:20px;'>Cross-docking is a kind of process that products are unloaded in front the inbound doors, consolidated based on downstream demand, and then directly transferred to outbound doors without long storage during transportation. In this paper, multi-door cross-dock truck scheduling problem investigated which sequencing assignment trucks need be considered, with obje...
