This study presents the development of a material selection decision support system for an automotive rooftop tent. The system uses five parameters of material cost, formability, corrosion resistance, tensile strength and hardness to optimize material choice from a list of aluminium alloy options. This was done before production via the deep drawing process can commence. The parameters were quantified using the average market prices for each alloy, product requirements obtained from the case study and the performance data that was obtained from the uniaxial tensile and hardness tests. These inputs were combined with the developed material selection framework and then programmed into a web-based decision support system for automated, data-driven material selection. The output presents the recommendation for the optimum material that balances cost-effectiveness and performance. The decision support system was successfully used to select the optimum alloy for the rooftop tent. Results show that AA1050 is the optimum material, providing weight reduction at the minimum achievable cost without compromising the product requirements for the rooftop tent. The decision support system is also scalable, and this allows it to be used with larger datasets for different products and processes in the future. © The Author(s) 2024.

Awareness about climate change has led to policies and regulations but also customer preferences favoring sustainable production. Thus, producing businesses are confronted by this, as they consume a large share of resources. Therefore, when producing, additional dimensions beyond commercial feasibility ought to be considered. Here, literature on sustainability from the field of engineering science is systematically searched and analyzed for approaches leading to actual recommendations for action. Hence, this bottom-up approach, incorporating the production engineers' point of view, represents an inside view of how the topic of sustainability has arrived at production companies. The focus on commercial feasibility ensures high relevance to practice, as production needs to become both sustainable and competitive. Even though exemplary collections of different approaches addressing the topic of sustainability in production can be found in literature, novelty is provided by the structured manner literature was collected and the special focus on approaches leading to practice-relevant recommendations for action. Thus, a comprehensive overview of approaches applicable to the manufacturing domain is presented. © 2023 The Authors. Published by Elsevier B.V.

Implementing processes for traceability is required in various industries to assure product quality during manufacturing, provide evidence on required processing conditions or facilitate product recalls. Commonly, radio-frequency identification (RFID) or code recognition techniques (e.g. Data Matrix) are applied to track the flow of workpieces through a manufacturing system and link processing data accordingly. Although the analysis of tracking data is well-examined, we still see a gap in the research on the trade-off between data acquisition, data analytics and data quality. Here, we present a framework to increase the value of existing data by enabling data analytics while addressing common pitfalls and reducing the costs of data management. © 2024 Elsevier B.V..

Open Source Hardware (OSH) enables innovative developments and business models. The OSH approach creates new forms of cross-company product development and community-based innovation processes. Open source has been state of the art in software industry for years. When it comes to OSH projects, however, the focus is primarily on the consumer sector. The use of OSH for industrial products, especially in mechanical engineering, is still in its early stages. The paper presents a case study on the development of an application module based on OSH components in a R&D testbed. The developed module is intended to enable electronic functional testing. For this purpose, the development process involved, among other things, creating solutions for a tool changing system. Using the case study, we analyse the advantages and disadvantages of the open source licenses used and derive implications for the R&D process. Building on this, various concepts for the use, adaptation and expansion of OSH components and the resulting implications for development processes and business models are presented. The case study is used to analyse which established open source software concepts can be transferred to material assets, but also which additional requirements arise from OSH components, e.g. in the area of safety. © 2024 The Authors.

The energy policy requirements help to make industrial production more sustainable and environmentally friendly, reduce energy consumption and lower the overall costs for businesses. There is a great need for action to increase energy efficiency in production in press hardening processes through efficient technologies along entire process chains. In such production processes and process chains, data accumulates from a wide variety of sources, including machine controls, sensors, material data and simulation data from process design. The logical next step is to utilize this data along with machine learning and optimization methods to control the process and pursuing objectives like optimal quality, minimal energy, or fast cycle times. This is where the proposed method of this work comes in. The main contribution of this work is a methodology to schematically describe and handle process optimizations model-based. In addition, this method is demonstrated on a hot forming process using hybrid (simulation and experimental) data. It is shown that the process can be optimized regarding its energy consumption while complying with additional technical and quality boundary conditions. © CHS2 2024 . All rights reserved.

The United Nations (UN) Sustainable Development Goal 13 focuses on taking urgent action to combat climate change and its impacts. Resource efficient production and strict emission regulations have made vehicle weight reduction a subject of great interest. Common lightweighting techniques include topology optimization and material substitution. The benefits include reduced raw material usage, low fuel consumption, and low carbon emissions. There is a gap in the complex balance of decision-making. If an engineer is faced with the option of topologically optimizing or materially substituting, is one method better than the other? This paper comparatively analyses these lightweight design strategies. © 2024 Elsevier B.V.. All rights reserved.

The trend towards globalization is increasingly being questioned or put under the microscope for social, political, and economic policy reasons. Due to the closely net-worked trade relations unpredictable events like pandemics, natural disasters, technical disruptions of supply chains and political conflicts can have considerable economic and social consequences. However, the central point is the constantly and rapidly changing market conditions to which it is necessary to react, or which must be shaped in order to adequately and successfully counter new technologies or new competitors. Within this paper it is worked out that based on targeted support of decision makers from top management to lower management and of the executing staff, the economic consequences for companies can be lowered with data-driven approaches and furthermore the. The objective of this paper is to help tackling reconfiguration needs via a holistic approach with the human being in the centre. The central hypothesis consists of the fact that with standards and defined methods, data-driven tools such as the digital twin or dedicated software applications for decision support specifically for information-based decisions, it is possible to deal more robustly and resiliently with rapid changes in the business environment. Based on exemplary use cases of automotive and medical technology as well as precision manufacturing of optical components, a holistic ecosystem platform RaRe2 will be developed, which will be disseminated as a reference for innovative software concepts on an industrial scale. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
