To avoid downtime, high procurement costs, and shortages, railway companies often stock large and costly inventories. However, additive manufacturing (AM) makes it possible to cost-effectively produce spare parts in small quantities to reduce inventory. To assess the suitability of a spare part and choose the optimal supply strategy, economic and technical data must be available in good quality. The lack of centralised information and poor data quality is one of the biggest challenges for AM potential assessment.</p><p>A workflow was designed, in which system data from various databases was mapped and enhanced with technical information. In addition, the potential for additive manufacturability was evaluated based on costs and savings affected by transportation, design, manufacturing, storage compared to other supply strategies. The resulting database was then used to classify the spare parts based on specific characteristics. The defined classes provide information about the timeline for implementing the part and the type of application.

This study proposes a life cycle simulation (LCS) based management method to support optimal decision-making under conditions that include various uncertainties, such as consumer behavior and market trends. LCS is a simulation method that simulates dynamic material flow in the entire life cycle system and enables the evaluation of environmental and economic efficiencies. Since the simulation model consists of many parameters, exhaustive simulations with all parameter combinations are impossible in a practical timeframe. Therefore, the method extracts parameters that have a significant impact on eco-efficiency through sensitivity analysis using LCS. Then, a response surface of multi-level resolution is created in a multidimensional space composed of the parameters. The response surface is used to quickly identify optimal parameter values under uncertain conditions for effective management. As a case study, the proposed method is applied to the management of a circular manufacturing system for lithium-ion batteries of automotive to verify the effectiveness of the management on eco-efficiency.</p></div>","PeriodicalId":20535,"journal":{"name":"Procedia CIRP","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2212827124000805/pdf?md5=1a5466303b93dd78e971282e8c729a4a&pid=1-s2.0-S2212827124000805-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140843352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is due to the information asymmetry between battery producers and end-of-life (EoL) actors. Tailoring a battery passport to EoL offers the opportunity to go beyond the current state of the art of battery passport legislation and add further details that are important for the recycling process. Therefore, this research looks at a suitable way to set up a battery passport to support the EoL of lithium-ion batteries. First, the data needs of the EoL phase were analyzed based on use cases described by eight experts through interviews. The results show a need for material related- and dynamic data, such as the state of health. The same expert interviews were then used to answer how these needed data could be provided. The results confirm the availability of most data but with gaps regarding dynamic data and use-phase information. Both the data needs and provision are then categorized and summarized into a data model. The discussion also provides an overview of the challenges and estimates the impact, depending on the scale of implementation.

One way of reusing metal chips that occur as waste in machining or other subtractive manufacturing processes is to mechanically pretreat and remelt them. In mechanical pretreatment, the chips are separated from the cutting fluid by a centrifuge and then briquetted directly on site. This simplifies the handling and makes the transport and subsequent remelting more efficient than in thermal processing alone. The main objective of this work is to quantitatively assess the environmental impacts of the described recycling process, focusing on the global warming potential. Furthermore, recycling by means of mechanical chip processing is compared with alternatives such as thermal drying and primary material extraction. A parametric life cycle assessment (LCA) model has been developed for this purpose. The model considers equipment, material, throughput and location variations to analyze different use cases. The results of the LCA of an exemplary use case show that environmental benefits result from a higher bulk density during transport and a lower energy input during remelting due to a lower liquid content.</p></div>","PeriodicalId":20535,"journal":{"name":"Procedia CIRP","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2212827124000404/pdf?md5=311e72c9ad5a013d1e1aad9ad3777be3&pid=1-s2.0-S2212827124000404-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140844197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
