Today's business world is characterized by ever-increasing complexity in nearly every dimension. Supply chains can no longer be understood in a linear fashion, but form networks across numerous supply chain participants. Globalization and crises are straining existing structures, calling into question previously set priorities and measures, and demanding new solutions. How must supply chains be structured in this constantly changing environment in order to be successful? This article highlights fields of action for successful supply chain management.

In current times, heavier fuels such as oil and diesel are generally used to power merchant and passenger ships alike. International and national regulations are likely to increase pressure to reduce greenhouse gas emissions of sulfur and nitrogen oxide, carbon dioxide, and fine dust pollution within the global maritime shipping industry. Green fuels are one possible solution for emission reduction. Therefore, the International Maritime Organization (IMO) create the International Convention for the Prevention of Pollution from Ships (MARPOL), Annex VI of which enables the enforcement of designated (sulfur) emission control areas (ECAs or SECAs). Current research shows that hydrogen and LNG fuels can be safely operated and used to supply electric generating systems and drive systems. Today, cruise ships are often constructed with LNG main propulsion engines. Conventional hydrogen and LNG fuels are not CO2 free. However, green hydrogen, green ammonia and green LNG are based on ...

Additive manufacturing processes are becoming increasingly important in industry and enable the cost-e ective production of complex components in small quantities. Small and medium-sized enterprises (SMEs) in particular can bene t from the high customization potential enabling the development of new business models. However, the widespread use of additive processes faces high production costs and technological challenges. Meanwhile, scienti c research focuses on the optimization of individual process steps of additive manufacturing and does not o er su cient support for SMEs. Therefore, this paper deals with the development of a cross-process value chain of additive manufacturing for SMEs. Based on a systematic analysis of scienti c literature, relevant additive manufacturing processes were investigated, and a cross-process value chain was derived. The results were veri ed by expert interviews and central research and development requirements were extracted.

The use of 5G technology o ers many companies enormous opportunities regarding their efforts to optimize processes. In particular, the intralogistics of a smart factory could bene t signi cantly from the use of 5G. The position of diverse mobile units can be determined precisely. Applications such as the control of Automated Guided Vehicles (AGV ) or the precise localization of material come into consideration. If the potential of 5G technology can be fully utilized and integrated into the structure of intralogistics, production processes could be revolutionized.
