Developing an adaptable VC architecture tailored for this industry, the study reveals SPES’s efficacy but highlights areas for improvement. Despite its strengths, limitations in decision support and clarity have been identified, recognizing the dynamic nature of industrial scenarios. Offering a valuable blueprint, the presented systematic development process aids researchers and practitioners in the evolving domain of VC and automated production systems. The developed architecture demonstrates the incorporation of complex industrial requirements. However, as the requirements are generic, such as scalability, the architecture is also applicable to other application scenarios.
- PublicationMetadata onlyOptimizing virtual commissioning of a robotic system using process mining and footprints conformance checking(IEEE, 2023-07)In the aircraft manufacturing industry, the process plans created for tasks such as automated drilling and riveting are lengthy and require prior testing and validation using Virtual Commissioning (VC), which can be time-consuming. The introduction of a new process plan requires the complete plan to be tested and validated again, exacerbating the challenge of testing and validating several plans or sequences in advance using VC. This research paper proposes using process mining and footprints conformance checking to reduce VC time for robotic systems. By integrating these techniques, differences in process plans can be detected, and only the new sequences or changes from an old to a new process plan need to be tested, significantly reducing the time needed to perform VC. This research implies that the developed approach can improve the efficiency of VC and ultimately enhance the performance of automated manufacturing systems.

- PublicationMetadata onlyExploring conflict- and target-related movement of visual attention(Sage Publishing, 2014-06-01)Intermixing trials of a visual search task with trials of a modified flanker task, the authors investigated whether the presentation of conflicting distractors at only one side (left or right) of a target stimulus triggers shifts of visual attention towards the contralateral side. Search time patterns provided evidence for lateral attention shifts only when participants performed the flanker task under an instruction assumed to widen the focus of attention, demonstrating that instruction-based control settings of an otherwise identical task can impact performance in an unrelated task. Contrasting conditions with response-related and response-unrelated distractors showed that shifting attention does not depend on response conflict and may be explained as stimulus-conflict-related withdrawal or target-related deployment of attention.
- PublicationMetadata onlyIrrelevant stimulus processing when switching between tasks(Hogrefe, 2013-01)Frequent switching between two tasks afforded by the same stimuli is associated with between-task congruency effects, that is, relatively impaired performance when a stimulus affords different responses as compared to the same responses in both tasks. These congruency effects indicate some form of application of the stimulus-response (S-R) rules of the currently irrelevant task. Between-task congruency effects are usually enhanced on task switch trials compared with task repetition trials. Here we investigate whether this interaction reflects stronger proactive interference from the irrelevant task on switch trials or whether performance on switch trials is characterized by generally enhanced susceptibility to task-irrelevant information processing. To this end, we contrasted between-task congruency effects with interference exerted from flanker stimuli taken from the current task (Experiment 1) and from spatial-numerical association of response codes (SNARC; Experiment 2). In both experiments, between-task congruency effects were larger on switch trials than on repetition trials, whereas interference from the other source remained constant, thus demonstrating that switch trials are not characterized by generally increased distractibility.
