Many planning and decision activities in logistics and supply chain management are based on forecasts of multiple time dependent factors. Therefore, the quality of planning depends on the quality of the forecasts. We compare different state-of-the-art forecasting methods in terms of forecasting performance. Differently from most existing research i...

Rapidly changing conditions, such as continuous layout shifts and process adaptions in smart warehouses pose challenges for robot mapping and navigation.

Advanced communication and perception capabilities are required to accomplish multi-robot perception and collective enviro...

Enhancing transparency in production processes, especially in shared manufacturing, relies heavily on sharing data. Information asymmetries and coordination problems between parties with conflicting interests pose a challenge in this multi-stakeholder interaction. Blockchain technology with smart contracting can be a solution due to its immutable d...

In times of ever faster learning machines, trust is an essential precondition for effective human-technology interaction (Rutinowski et al., 2024). We follow the definition of trust as the willingness of a party to be vulnerable to the actions of another party based on the expectation that the other will perform a particular action important to the...

The implementation of an automated guided vehicle (AGV) or automated guided vehicle system (AGVS) is currently manufacturer-dependent. In order to achieve independence and prevent a vendor lock-in, it is useful to apply standards to control for example a heterogeneous fleet of AGVs. The VDA 5050 is a first approach to make this possible. However, f...

In this paper, we apply answer set programming (ASP) to the task of planning warehouse layouts within the logistical domain. Warehouse layout planners have to take into account a vast number of aspects to come up with feasible layouts, especially the placement of logistical elements under specific conditions like the accessibility of warehouse elem...

The human eye consists of two types of photoreceptors, rods and cones. Rods are responsible for monochrome vision, and cones for color vision. The number of rods is much higher than the cones, which means that most human vision processing is done in monochrome. An event camera reports the change in pixel intensity and is analogous to rods. Event an...

A minimum requirement of feasible order picking layouts is the accessibility of every storage location. Obeying only this requirement typically leads to a vast amount of different layouts that are theoretically possible. Being able to generate all of these layouts automatically opens the door for new layouts and is valuable training data for reinfo...

How can we segment varying numbers of objects where each specific object represents its own separate class? To make the problem even more realistic, how can we add and delete classes on the fly without retraining? This is the case of robotic applications where no datasets of the objects exist or application that includes thousands of objects (E.g.,...
