Simulating computed tomography (CT) systems offers numerous advantages, including the optimization of scan parameters, training of specialist personnel, and quantification of measurement uncertainties. Current simulation approaches, often referred to as virtual computed tomography (vCT), predominantly rely on analytical models. However, these model...

In the context of growing sustainability demands, businesses are increasingly adapting their production practices by integrating remanufacturing. However, companies often face challenges in profitably implementing remanufacturing due to complexities arising from uncertainties in processes, product quality, and market conditions. This highlights the...

In remanufacturing, humans perform visual inspection tasks manually. In doing so, human inspectors implicitly solve variants of visual acquisition planning problems. Nowadays, solutions to these problems are computed based on the object geometry of the object to be inspected. In remanufacturing, however, there are often many product variants, and t...

Referenzbauteile mit Defektmerkmalen sind essentiell für die Erprobung von Prüfverfahren in der Qualitätssicherung der Brennstoffzellenfertigung. Aufgrund der schlechten Zugänglichkeit von defekten Bipolarplatten wird in diesem Beitrag ein Lösungsansatz vorgestellt, bei dem die zu untersuchenden Defektbilder gezielt in die Geometrie der Bipolarplat...

The trends of shorter product lifecycles, customized products, and volatile market environments require manufacturers to reconfigure their production increasingly frequent to maintain competitiveness and customer satisfaction. More frequent reconfigurations, however, are linked to increased efforts in production planning and control (PPC). This pos...

In modern markets, increasing quality requirements require high performance quality assurance processes which guarantee the fulfillment of these requirements sustainably. The quality assurance must therefore be able to take targeted countermeasures in the event of deviations. It is becoming increasingly decisive to achieve quality with minimum reso...

With the introduction of new technologies, the scope of miniaturization has broadened. The conditions under which complicated products are designed, manufactured, and assembled ultimately influence how well they perform. The intricacy and crucial functionality of products are frequently only fulfilled through the use of high-precision components su...

Process-induced residual stress is a major challenge in today's additive manufacturing (AM) processes, such as powder bed fusion by laser beam melting of metal. After the AM process, the exact stress state is usually unknown, and parts often require heat treatment to relieve residual stress. In-process measurement of residual stress is currently no...

While attracting increasing research attention in science and technology, Machine Learning (ML) is playing a critical role in the digitalization of manufacturing operations towards Industry 4.0. Recently, ML has been applied in several fields of production engineering to solve a variety of tasks with different levels of complexity and performance....

The increasing digitalisation and development of the fourth industrial revolution have created new opportunities in the B2B manufacturing industry. These opportunities come in the form of smart services, which are made possible by the interconnectedness of machines and products and the collection and analysis of data. However, there is uncertainty...

Industrielle Computertomographie erfordert umfassendes Expertenwissen. In diesem Beitrag wird ein Konzept vorgestellt, um die Parametrisierung von Messungen durch Reinforcement Learning zu automatisieren. Innerhalb einer Simulation sollen Agenten Messstrategien wie das Auslegen zeitminimaler Messungen erlernen. Auch wenn aktuelle virtuelle CTs real...

In production networks, production must run efficiently across company boundaries. Companies must be able to react quickly as a single unit. Two trends are influencing this situation: On the one hand, the progressing servitization leads to the increased offering of digital services in the field of manufacturing. From the literature, it is known tha...

In today's world, manufacturing companies face many challenges due to the uncertainty and complexity of environmental influences as well as increasing competitive pressures. The pandemic has clearly illustrated how volatile and fragile our supply chains have become. One way to overcome these chal-lenges together is to collaborate with other compani...

In der heutigen Zeit stehen produzierende Unternehmen aufgrund der Unsicherheit und Komplexität von Umwelteinflüssen sowie des wachsenden Wettbewerbsdrucks vielen Her-ausforderungen gegenüber. Die Pandemie hat uns deutlich veranschaulicht, wie volatil und fragil unsere Lieferketten geworden sind. Eine Möglichkeit, diese Herausforderungen gemeinsam...

In the context of managing global production networks, the way customer orders are planned and scheduled in the production network highly affects a company’s competitiveness. A well-defined and well-executed planning process enables manufacturing companies to satisfy their customers’ needs to a high degree while keeping production costs at a low le...

Supply chain planning in global production networks is a very difficult task due to the high diversity of products and machines and the immense number of possible configurations. An important task in this area is capability matchmaking: finding machines that are capable to produce specific parts. Today, this is done by experienced engineers who hav...

The ongoing individualization of products forces companies to focus more on flexibility and adaptability. To achieve this, cooperating companies need to intensify their cooperation into collaboration. New types of collaboration are enabled by a wave of digitalization reducing organizational efforts and risks of collaboration. Especially smart servi...

Collaboration in global production networks becomes more important in times of increased interconnectivity and complexity. However, due to various resistors the collaboration potential has not been realized, yet. At the same time digitalization has become a key enabler in today’s world of high complexity leading to new, disruptive solutions. Part o...

Für produzierende Unternehmen nehmen Smart Services weiter an Bedeutung zu. Daher ist eine einheitliche Methode wichtig, um diese Services im Umfeld von Produktionsnetzwerken zu entwerfen sowie Geschäftsmodelle für netzwerkbasierte Smart Services aufstellen zu können. Es wird ein Vorgehen vorgestellt, um Smart Services im Kontext von Produktionsnet...

Kurzfassung Die Technologien von Industrie 4.0 bieten global produzierenden Unternehmen die Chance, Entscheidungen zur Netzwerkgestaltung zu verbessern und die Steuerung der Produktion weltweit zu synchronisieren.
