Published: April 2023

AbstractOn the path towards a sustainable society, the availability of energy storage systems is an essential step – leading to increased demand for batteries. To achieve a sustainable society, it is necessary to manufacture batteries also in a sustainable way. One approach lies in virtual experiments. They aim at identifying parameters, recipes, and technologies in the digital world, before applying them to the physical production system. Thus, manufacturing is optimized in regard to sustainability indicators such as material consumption, emission, and waste – but also in regard to costs, quality, and yield. The faster ramp-up is especially important in the production of battery cells, due to the highly complex processes and critical materials. In this paper, we introduce a concept for virtual experiments platform in battery cell production. It includes collection of data, data aggregation, a simulation environment, as well as an optimizer. Also, it is integrated into existing production and IT systems. The virtual experiments platform functions as a service of a digital twin. Validation is conducted by realizing the virtual experiments platform on the electrode production of lithium-ion batteries.

Authors: Schramm N. , Oertwig N. , Kohl H. 
Published: April 2023

AbstractThis paper addresses the megatrend of urbanization as well as the associated challenges of climate change and its relation to sustainable manufacturing. An enormous lever for improving the climate balance is offered by the consistent use of renewable building materials. In the Berlin/Brandenburg metropolitan region, wood as a building material in particular should play a central role in achieving the climate targets. To realize this, it is not only necessary to use the potential of wood as a raw material for storing carbon, but also to embed wood construction in regional value chains and integrated digital production systems in order to be able to optimally design innovative value creation fields, new regional products and efficient material cycles for increasing sustainability. In the context of this work, the information flows along the value chain are investigated and transferred into a digital model. Existing digital concepts such as the “Open BIM” approach (Building Information Modeling) have been incorporated and shape the entirety of the value chain module developed in this paper for serial prefabrication in multi-story timber construction. Material and information flows are analyzed, interfaces between the actors are identified, value-adding factors of timber system construction are systematically examined for their effects, and industrial prefabrication is aligned with a digital model.

Published: April 2023

AbstractAdditive Manufacturing (AM) is a key Fourth Industrial Revolution (4IR) technology in which parts are manufactured directly from 3-dimensional models through selective deposition of materials. As a digital technology, AM can be used to produce complex parts that are difficult to make using traditional methods without the need for tooling. Hence, the aim of this study is to investigate the performance of Fused Deposition Modelling (FDM) in the manufacture of pump impellers. This involves performing simulation to test the performance of pump impeller under real-life working conditions at different operating speeds and pressures. The model of the impeller as casted in the FDM process was developed in the complete Abaqus modelling environment. The model part was created as single solid homogenous part with no nodal separations or assembly ties or constraints between the base of the impeller and its blades, in relation to its as-cast manufacturing state. The results obtained showed that extreme operating speeds of up to 1000 rad/s or pressures of 0.22 MPa are not suitable conditions under which the impeller will operate without compromising its efficiency and structural integrity. The study is useful in providing guidance on the application of FDM to produce functional parts. Through the study, the capability of AM as a suitable approach for enabling local sustainable production of spare parts is demonstrated.
Framework for Sustainability in Aerospace: A Proof of Concept on Decision Making and Scenario Comparison
Authors: Franchino Marco 
Published: April 2023

AbstractAerospace is a large and growing industry currently dependent on fossil fuels. UK aviation has committed to achieving net zero emissions by 2050.In order for the UK aerospace sector to achieve the sustainability goals, it needs to use the latest technologies while making sure to minimise negative environmental impacts.Ongoing debates claims that the definition of sustainability and its assessment is vague. Companies struggle with quantifying the return on their sustainability investments and necessitate a methodology to aid decision making and quantify improvements against sustainability and profitability. For that reason, this investigation focused on defining a framework to assess sustainability for aerospace manufacturing following a triple bottom line (TBL): profit, people (social responsibility) and planet.The author surveyed a range of major aerospace businesses, including Airbus, BAE Systems, Boeing, GKN, Rolls-Royce and Spirit Aerosystems, who are all industrial partners at the University of Sheffield Advanced Manufacturing Research Centre (AMRC). These businesses are all working together to identify and solve the common challenges associated with sustainable manufacturing and contributed their thoughts to the development of this definition.Collected information has been integrated in a trade study framework that helps scenario comparison and decision making. Discrete Event Simulation (DES) has been used to test the methodology, defining and quantifying alternative scenarios. The framework developed in this study aims to help ensuring that aerospace companies remain profitable whilst also fulfilling the industrial Partners’ environmental and societal obligations.

Published: April 2023

AbstractAdditive Manufacturing (AM) as much as sustainability aspects gained increasing attention in the last couple of years. The vision of resource-efficient manufacturing at batch size one is often claimed as an outstanding property of AM. Fused Filament Fabrication, as one of the most used AM technologies, satisfies this statement only in a restricted sense, through simple handling for non-experts and low-cost materials and machines. Next to performance-driven and process-influencing attributes, the question of a general ecological improvement through thermo-mechanical recycling rises. Therefore, recycling options of the thermoplastics are mandatory to explore. Based on the ISO 14040/44 Life Cycle Assessment (LCA) methodology two different geometries were environmentally assessed during a primary process cycle, using, and recycling. Each geometry was manufactured by a bio-based polymer and internationally produced (PLA) and petroleum-based locally produced polymer (PP) with a corresponding support filament. The methodological approach demonstrates an option how to evaluate the field of AM and recycling regarding environmental aspects. Furthermore, an adaption of the sensitivity towards industrial parameters (material/energy efficiency) showed an ecological benefit concerning recycling.
Considering LCA in System Architectures of Smart-Circular PSS

Published: April 2023

AbstractThe realization of smart-circular Product-Service Systems has theoretically promising advantages compared to traditional products. Nevertheless, the sustainability improvement, especially for the ecological dimension is not yet satisfactorily proved. In this paper, the authors examined the current state of research within a systematic literature review with a specific focus on the overlap of the topics: Life Cycle Assessment, Model-Based Systems Engineering, Product-Service Systems, and Circular Economy. The aim is to analyze the potential of a proactive quantification of the ecological impact in an early stage during the development of smart-circular PSS – the system architecture definition. As a result of the systematic review, 27 relevant papers were identified and analyzed and the findings are presented in a structured way. The main finding is that the current state of the art in this research field still is in the conceptualization stage. In addition, a proactive approach is rare and circularity is not considered to its fullest. Quantified use cases do not draw the system boundaries Cradle-to-Cradle and not every of the 9R-strategies is considered. Furthermore, the potentials and challenges of the revealed research gap are summarized.

Published: April 2023

AbstractThis paper introduces the work on dynamic life cycle assessment (LCA) and life cycle costing (LCC) carried out within the EU Horizon 2020 project ECOFACT. The goal of the ECOFACT project is to develop a digital platform for manufacturing companies to optimize their production systems for energy, costs, resources and life cycle impacts. The platform will include a manufacturing decision-support-system based on dynamic LCA and LCC and it will be demonstrated in four factories that are members of the project consortium. Dynamic and automated LCA and LCC provides opportunities for new insights compared to conventional, static assessments. For example, temporal variations in the environmental impact can be made available on an hourly, daily, monthly and yearly basis. Moreover, once set up, LCA and LCC results can automatically be updated with the latest data, reducing efforts and costs related to data collection and reporting. In this paper, we briefly explain the ECOFACT approach to dynamic LCA and LCC and discuss preliminary learnings as well as future opportunities.
Digital Supply Chain Twins for Sustainable Planning of a Logistics System
Authors: Zarnitz Simon , Straube Frank , Nitsche Benjamin 
Published: April 2023

AbstractDigital Supply Chain Twins (DSCT) are gaining more and more attention both in science and in practices. They are considered to be one of the most disruptive technologies in logistics and supply chain management. In the literature, there are a variety of DSCT benefits in the case of planning and control a logistics system. Some of these potentials could also be highly suitable for the use case of sustainable and resource-efficient logistics, which, however, have been insufficiently explored in research so far. This paper will investigate to what extent the DSCT can be used to enable sustainable network planning and which potentials the DSCT implies for the predictive planning within logistics systems. Building on a literature review and interviews with industry experts a case study was conducted at a business partner in the automotive industry.

Authors: Haddad Yousef , Jagtap Sandeep , Pagone Emanuele , Salonitis Konstantinos 
Published: April 2023

AbstractIn this paper, a life cycle assessment (LCA)-based sustainability assessment framework is developed to estimate the environmental impact of production processes. The framework provides a methodical, context-independent, approach to carry out LCA studies. The framework sets guiding principles for products and key performance indicators (KPIs) selection and the associated data requirements in a reconfigurable manner that can be applied to any industrial setting. In order to validate and demonstrate the applicability of the framework, a cradle-to-gate case study pertaining to the manufacturing of a real aerospace metallic structural component is carried out. Results revealed that the complexity of aerospace components makes it difficult to improve the environmental impact from manufacturing operations as most of the impact comes from upstream activities that aerospace manufacturers, typically, have no control over, or access to.

Published: April 2023

AbstractSustainable product development is one key to avoid overshooting the global production resources and to keep the human impact on the climate under control. Life cycle assessment provides methods and tools to monitor and quantify processes. In reality however, this is a complex procedure with a lack of transparency and standardization. Especially small and medium enterprises lack resources and know-how to successfully perform life cycle assessments. Therefore, the need for action is to make methods and tools usable and accessible in practice. This paper presents a concept for the evaluation and categorization of sustainability assessment methods and tools by developing criteria based on a system context and stakeholder analysis. Proven assessment methods from literature and market research are the basis for the development of this concept. The final evaluation of exemplary solutions leads to research gaps which can be addressed in the future development of assessment methods.

Published: April 2023

AbstractCO2 neutrality is an important goal for the upcoming years. It is necessary to ensure that greenhouse gases are emitted as few as possible, particularly for the development of new products. The most important decisions, with impact on the sustainability, are already made by the product designer during the virtual product development phase, such as raw material requirements, selected manufacturing process or thermal and surface treatments. Especially in the case of ablative processes (CNC), raw material has a major impact on the calculated carbon footprint of products.In order to minimize the emissions of greenhouse gases in the virtual product development phase already, this paper presents an approach to provide assistance for the product designer regarding the ecological impact of his decisions. For this purpose, Life Cycle Assessment (LCA) methods are directly integrated into the CAD software. During the design process, the expected CO2 equivalents of the largest influencing factor - the raw material - can be displayed which is observed for most cases of metal material. In addition, the savings potential for reducing the blank volume or changing the raw material is shown and a suggestion is made.
A Fuzzy Sustainable Quality Function Deployment Approach to Design for Disassembly with Industry 4.0 Technologies Enablers
Authors: Keivanpour Samira 
Published: April 2023

AbstractIntegrating sustainability into product design is a proactive circular economy practice and design for disassembly is an essential eco-design practice for complex product manufacturers. Today, industry 4.0 technologies have considerable influence on product life cycle management, and a few studies address the contributions of these technologies to eco-design methods. Designing the appropriate eco-design tool is challenging considering the complexity of products, organizational instruments, the need for integrating diverse databases, customization of the tool, and incorporating the strategic goals. Hence, a systematic approach is required to address the implications of innovative technologies and integrate the different technical, economic, environmental, and social aspects into the design stage. Quality function deployment (QFD) is an effective approach to integrating customers, technical, and business requirements into new product development. Fuzzy Sustainable QFD is an extended version of this method for considering three pillars of sustainability in design and dealing with qualitative linguistic judgments. This paper proposes a Fuzzy sustainable QFD approach to design for disassembly. A numerical example illustrates the application of the proposed method.

Published: April 2023

AbstractAlthough production planning in remanufacturing systems has attracted great interest from the research community, only a couple of real industrial applications can be perceived. Additionally, in real cases, companies are faced with manufacturing multiple products, which further complicates remanufacturing production planning (RPP). Therefore, there is a need to optimise RPP where manufacturers are involved in remanufacturing multiple products. Also optimized systems should consist of a number of uncertainties, such as the uncertain quality of the returned products.Because of these uncertainties the manufacturers have to use new parts or components - with both higher environmental impacts, as well as costs. In the present paper a line balancing scheduler of a remanufacturing system is presented - focusing on the disassembly, machining and reassembly of parts. The objective of the paper is the reduction of usage of the energy and cost intensive new parts with production scheduling using a genetic algorithm (GA). The achievements are illustrated and presented with a real industrial use case from a gas engine producer. A discrete event simulation (DES) is used for evaluation purposes and the results from the scheduler are compared with benchmarks of the current production planning of the gas engine manufacturer.
Serious Games in Academic Education – A Multi-dimensional Sustainability Analysis of Additive Versus Conventional Manufacturing Technologies in a Fictitious Enterprise Project
Authors: Rauch Christiane , Maurer Oliver , Lang Sven-Erik , Bähre Dirk 
Published: April 2023

AbstractMetal additive manufacturing among other advantage offers a high degree of freedom in the design of components and shortening of conventional manufacturing process chains. Hence, there are questions of technological feasibility, efficiency and sustainability. Current relevant studies, especially on the sustainability of selective laser melting, often examine only one aspect. At the same time, companies in various sectors are faced with the question of whether and if so, to what extent it is worth converting their production towards additive manufacturing units. In any case, the context is filled with complex issues in several decision-making dimensions.In this paper, a special concept for academic education is introduced. It mirrors the complexity of decision-making issues, relevant problems and solutions, in a fictitious enterprise project named „AM for Future!?”. The project is played as a serious game with an explicit educational purpose. It is an adaptable toolbox-like game structure on a solid methodical basis. Besides clear roles with a focus on different dimensions of sustainability, it also enables variation of products and process chains. Gameplays of different project settings, spanning over three consecutive semesters, confirm the game plan as a safe environment and suitable world of experience. For research, the output of the different game seasons can be used as a simplified parameter study. This applies to objectively quantifiable as well as different qualitative approaches. These approaches influence the answer to the question of whether and, if so, how a conventional process chain can be specifically replaced and/or supplemented with metal additive manufacturing.
Federated Learning for Privacy-Preserving Collaboration in Smart Manufacturing

Published: April 2023

AbstractManufacturers today are increasingly connected as part of a smart and connected community. This transformation offers great potential to deepen their collaborations through resource and knowledge sharing. While the benefits of artificial intelligence (AI) have been increasingly demonstrated for data-driven modeling, data privacy has remained a major concern. Consequently, information embedded in data collected by individual manufacturers is typically siloed within the bounds of the data owners and thus under-utilized. This paper describes an approach to tackling this challenge by federated learning, where each data owner contributes to the creation of a global data model by computing a local update of relevant model parameters based on its own data. The local updates are then aggregated by a central server to train a global model. Since only the model parameters instead of the data are shared across the various data owners, data-privacy is preserved. Evaluation using sensor data for machine condition monitoring has shown that the global model produced by federated learning is more accurate and robust than the local models established by each of the single data owners. The result demonstrates the benefit of secure information sharing for individual manufacturers, especially Small and Mid-Sized Manufacturers (SMMs), for improved sustainable operation.

Published: April 2023

AbstractThis article tackles the problem of greening university campuses of higher education institutions in Palestine. The paper concentrates on finding the adequate greening categories and key performance indicators to be used to assess the sustainability and green of higher education Institutions HEI. Each indicator has been weighted based on the opinion survey filled by academic experts from the different Palestinian universities. The weights of these indicators have been normalized to come up with a category score and a then a total score of the greening of the HEI. Eventually, a Go-Green integrated model is developed to form an initiative for any higher education institution wishes to enter into this sustainability race. Many steps and activities are suggested to turn any university to a green one. Through implying the Elasticity and Plasticity approach, it is possible to relate the level of green actions to social behavior. The impact of these sustainability aspects is reflected on higher education by implementation on university campus greening.
