Digital Product Passports

Digital Product Passports

Enabler of the circular economy
Moritz Hörger, Yannik Hermann, Magnus Kandler, Kevin Gleich ORCID Icon, Gisela Lanza ORCID Icon
Digital product passports are becoming increasingly mandatory for monitoring saving targets within the framework of EU-wide emission reductions. DPPs can enable a standardized exchange of emissions data along the entire product life cycle. A framework for systematic introduction and targeted use can simplify their often difficult practical integration, especially for small and medium-sized companies.

Robustness-enabling Properties in Business Processes

Robustness-enabling Properties in Business Processes

Identification and evaluation of characteristics related to robustness
Annika Lange ORCID Icon, Jens Mathis Rieckmann ORCID Icon, Jan Lukas Schmidt ORCID Icon, Thomas Knothe ORCID Icon
The crises of recent years have highlighted the importance of robust business processes. Even if the concept of robustness is often not clearly defined in the context of entrepreneurial activity, it can certainly be defined on the basis of various factors such as agility, adaptability and resilience. A systematic analysis of robustness and its prerequisites in the corporate context is therefore highly relevant, especially in times characterized by uncertainty.

Digital Maintenance Logistics

Digital Maintenance Logistics

Survey to determine the status quo of German agricultural businesses
Iris Hausladen ORCID Icon, Andreas Matthes ORCID Icon, Philipp Sylla ORCID Icon
Nowadays, maintenance logistics is considered an integral part of sustainable maintenance management and is now conducted with IT support in many of the fields where it is applied. It can therefore be seen as one of many examples of digitalization in the working world. Both the selected maintenance strategy, the implementation of which is more or less linked to the use of intelligent technologies, and the current level of IT integration are emblematic of the degree of digitalization in this context. In the agricultural sector, the type of maintenance objects in question plays an important role in the use of digital technologies. This article is dedicated to investigating the status quo of digital maintenance logistics in German agricultural businesses at the interface of ICT, technology and business.

Using Process Mining to Improve Logistics Performance in Production

Using Process Mining to Improve Logistics Performance in Production

An application from customized hydraulic component manufacturing
Christoph Koch, Sarveshwaran Murugan, Heiko Berchtold
Short delivery times are essential in competitive markets. In addition to product selection and quality requirements, customers are also demanding more and more from logistics. However, high product variance complicates the situation, as it involves complex material flows and therefore leads to long throughput times. However, a four-step process analysis and modeling can help to reduce throughput times and strengthen the competitiveness of companies from within.

Digital Platform Frameworks for Manufacturing Companies

Digital Platform Frameworks for Manufacturing Companies

A review
Marcel Rojahn ORCID Icon
In recent years, digital platforms have established themselves as a central concept in the IT field. Due to the wide variety of digital platforms available on the market, there is still a need for clear comparison with criteria to enable interested parties to select, change, operate and further develop these platforms. The following paper aims to contribute to the facilitation of this comparison by undertaking a systematic literature review of digital platform frameworks in the context of the Industrial Internet of Things (IIOT) for manufacturing companies and thus providing a basis for a number of potential ways to effectively compare current digital platforms and ecosystems.

Warehouse Inventory Detection with Airship Drones

Warehouse Inventory Detection with Airship Drones

(Semi-)autonomous aircraft for inventory and quality inspection of pallets in block storage facilities
Dmitrij Boger, Michael Freitag ORCID Icon, Britta Hilt, Michael Lütjen ORCID Icon, Benjamin Staar ORCID Icon
The complex dynamics of block warehouses pose major challenges to the manual stocktaking process. Frequent relocation of pallets, crates or pallet cages without fixed storage locations leads to a time-consuming and error-prone inventory process, wherein goods often have to be searched for and damages due to improper storage can occur. The use of (semi-)autonomous drones offers a promising solution to enable automated stocktaking, especially if these are appropriately equipped for optical goods detection.

Energy Efficiency Through Intelligent Electricity Data Acquisition

Energy Efficiency Through Intelligent Electricity Data Acquisition

Wireless retrofit solution based on IoT technologies and open-source software for existing industrial buildings
Sergej Kreber, Kevin Kutzner, Dieter Uckelmann ORCID Icon
Facility managers for industrial properties are faced with the challenge of optimizing the energy efficiency of their facilities in the face of ever-increasing energy demand and rising energy costs. Digital processes that enable the comprehensive monitoring, analysis and control of energy demand offer an effective way to reduce costs, increase energy efficiency and make optimal use of resources. Based on IoT technologies and open-source software, a cost-effective, wireless and flexible retrofit solution for real-time energy data collection has been developed.

Safeguarding Against Risks in the Wire Arc Additive Manufacturing Process

Safeguarding Against Risks in the Wire Arc Additive Manufacturing Process

Lennart Grüger ORCID Icon, Tim Sebastian Fischer, Ralf Woll, Johannes Buhl ORCID Icon
In this article, the potential risks in wire arc additive manufacturing are analyzed using failure mode and effects analysis. To achieve this, 186 possible causes of risk were analyzed and the five most critical risks were discussed in detail. Four significant risk factors were identified in the construction process. The fifth risk relates to the shielding gas flow. This is only one influencing factor among the welding parameters, which have strong interactions with each other. Therefore, their relationships should be analyzed on the basis of numerous tests.

Sustainable HR Management

Sustainable HR Management

Its importance for realizing sustainability in industrial manufacturing
Uta Kirschten
Industrial manufacturing offers a wide range of opportunities for a more ecologically compatible and socially just organization. Sustainability-oriented HR management can competently support industrial manufacturing companies in the design and implementation of sustainable manufacturing. It is important to integrate ecological, social and economic requirements into the respective areas of responsibility. In addition, employees must be motivated and qualified to adopt environmentally friendly working practices in order to be able to implement sustainable manufacturing in practice. Sustainable incentive systems and employee-oriented personnel management must also be taken into account.

Circularity Navigator

Circularity Navigator

Digital decision support for anchoring design for circularity in product development
Anina Kusch ORCID Icon, Annika Pruhs ORCID Icon, Jörg Woidasky ORCID Icon, Jonas Brinker ORCID Icon
Products cannot be included early enough in the planning of a circular manufacturing process. However, because early incorporation brings additional complexity into play, product decisions are often set aside for later manufacturing stages. At this point, a decision-making tool that systematically reduces complexity and generally simplifies the process is therefore of great value – especially if it can also be used as a source of inspiration and orientation aid in the innovation phase.
