Eine Herausforderung bei der Gestaltung kollaborativer Montagesysteme liegt in der optimalen Aufgabenzuordnung für Mensch und Roboter. Dabei soll sowohl eine geringe Durchlaufzeit als auch eine optimale Ausnutzung der Stärken der jeweiligen Ressource erreicht werden. In der Praxis stehen diese beiden Ziele häufig im Konflikt. In diesem Artikel wird eine Methodik zur kennzahlenorientierten Aufgabenzuordnung in MRK-Systemen vorgestellt, die es erlaubt, sich in diesem Zielkonflikt bewusst zu positionieren.   One challenge in the design of collaborative assembly systems lies in the optimal assignment of tasks to humans or robots. Both, a short throughput time and an optimal exploitation of the advantages of each resource should be achieved. However, these are usually two conflicting goals. This paper describes a methodology for the assignment of tasks in collaborative assembly systems which allows for a deliberate alignment within the range of these conflicting objectives.

Abstract Human-robot collaboration, whereby the human and the robot join their forces to achieve a task, opens new application opportunities in manufacturing. Robots can perform precise and repetitive operations while humans can execute tasks that require dexterity and problem-solving abilities. Moreover, collaborative robots can take over heavy-duty tasks. Musculoskeletal disorders (MSDs) are a serious health concern and the primary cause of absenteeism at work. While the role of the human is still essential in flexible production environment, the robot can help decreasing the workload of workers. This paper describes a novel framework for task allocation of human-robot assembly applications based on capabilities and ergonomics considerations. Capable agents are determined on the basis of agent characteristics and task requirements. Ergonomics is integrated by measuring the human body posture and the related workload. The developed framework was validated on a gearbox assembly use case using the collaborative robot Baxter.

Die Montageplanung muss trotz kurzer Planungszyklen in der frühen Produktentwicklung die Effekte neuer Bauteilvarianten auf Montagesysteme im Detail bewerten. Um den Aufwand bei der Pflege der Variantendaten zu reduzieren, wird eine Logik entwickelt, mit der sich die Baubarkeit der Bauteilvarianz an einzelnen Montagestationen effizient auswerten lässt. Zudem wird ein Vorgehen zum teilautomatischen Abgleich geometrischer Bauteil-Ausprägungen aus CAD-Modellen mit Montagerestriktionen vorgestellt.   In spite of short planning cycles, assembly planning must do in-depth evaluations of effects of new component variants on assembly systems in early stages of product development. To reduce the effort of data management, a logic is developed to efficiently analyse the mountability of the part variance on specific assembly stations. Moreover, a method for the partly automated comparison of geometric characteristics of components out of CAD models with assembly restrictions is presented.

Task Assignment Problem

The problem of scheduling is an area that has attracted a lot of attention from researchers for many years. Its goal is to optimize resources in the system. The lecturer’s assigning task is an example of the timetabling problem, a class of scheduling. This study introduces a mathematical model to assign constrained tasks (the time and required skills) to university lecturers. Our model is capable of generating a calendar that maximizes faculty expectations. The formulated problem is in the form of a multi-objective problem that requires the trade-off between two or more conflicting objectives to indicate the optimal solution. We use the compromise programming approach to the multi-objective problem to solve this. We then proposed the new version of the Genetic Algorithm to solve the introduced model. Finally, we tested the model and algorithm with real scheduling data, including 139 sections of 17 subjects to 27 lecturers in 10 timeslots. Finally, a web application supports the decision-maker to visualize and manipulate the obtained results.

AbstractAssembly represents a fundamental step in manufacturing, being a time-consuming and costly process, on which the final quality of the product mostly depends. Augmented Reality (AR) may represent a key tool to assist workers during assembly, thanks to the possibility to provide the user of real-time instructions and information superimposed on the work environment. Many implementations have been developed by industries and academic institutions for both manual and collaborative assembly. Among the most remarkable examples of the last few years are applications in guidance of complex tasks, training of personnel, quality control and inspection. This keynote paper aims to provide a useful survey by reviewing recent applications of AR in assembly systems, describing potential advantages, as well as current limitations and future perspectives.

Für eine Kompetenzentwicklung im Wertschöpfungsprozess müssen Schnittstellen für die Interaktion mit dem System lernförderlich gestaltet sein. In der Mensch-Roboter-Kollaboration, zum Beispiel in der Montage, kann eine lernförderliche Gestaltung der visuellen, auditiven und haptischen Systeminteraktion die Informationsakquisition unterstützen. Hierzu wurden Gestaltungskriterien für die Systeminteraktion erstellt und auf einen Mensch-Roboter-Arbeitsplatzes angewandt.   To develop competence in the value-adding process, interfaces for interaction with the system must be designed to promote learning. In human-robot collaboration, e.g. in assembly, a design for visual, auditory and haptic system interaction that is conducive to learning can support information acquisition. For this purpose, design criteria for system interaction were developed and applied to the design of a human-robot workstation.
