Automotive OEMs undertake the necessary efforts to ensure the integration of safe and high-performance battery cells in their electrified fleets. In addition, an increased sustainable awareness of their customers and governmental policies force them to not only focus on operational goals, but rather on environmental aspects as well. Especially, battery cell manufacturing is associated with various negative environmental impacts (e.g. carbon dioxide emission). Therefore, this study develops a concept facilitating the development of novel continuous processes in battery cell manufacturing by enabling virtual experiments and an automatic optimization of economic and ecologic targets. Virtual experiments are enabled by training data-driven models that transfer the gained knowledge from development to large-scale production. The concept includes an inline-capable controller adjusting set points of process parameters with respect to a cost model quantifying product quality and environmental aspects. The validity of the proposed concept is demonstrated with data acquired from real battery cell production chain covering a continuous mixing process.</p></div>","PeriodicalId":34573,"journal":{"name":"Advances in Industrial and Manufacturing Engineering","volume":"4 ","pages":"Article 100078"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666912922000083/pdfft?md5=c94f4e664b06ccc75b086c389805175e&pid=1-s2.0-S2666912922000083-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49181420","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}

Although this set of strategies allows optimizing the production by reducing waste, the literature review showed that, in several organizations, the implementation of Lean does not reflect positive impacts on productivity. It is frequently related to the superficial nature of the approach: the tools and methods are applied, but the repercussions on the workers are commonly neglected. In response, companies seek to implement Risk Management policies to assess injury risk factors for operators during task execution. This study highlights the importance of integrating Lean Manufacturing and Ergonomics principles into organizations to increase productivity and improve working conditions simultaneously. Therefore, by identifying improvement opportunities using the VSM tool, this work aims to implement an innovative and systematic intervention model, which enables the integrated application of Single-Minute Exchange of Dies (SMED) and ergonomic analysis in a metallurgical factory. To this end, the innovative Ergonomic SMED (ESMED) Model is proposed, comprising six steps, which, in this study, focus on the setup operations of a molding machine and by including Rapid Upper Limb Assessment (RULA), Rapid Entire Body Assessment (REBA), Job Strain Index (JSI), Key Indicator Methods (KIM), and Shoaf's Model methods. Based on the results obtained, it is possible to evidence the usefulness and effectiveness of the proposed model in this scenario, emphasizing the 55% reduction in setup time and the extreme attenuation of the level of Work-Related Musculoskeletal Disorders (WMSDs) risk in workers.</p></div>","PeriodicalId":34573,"journal":{"name":"Advances in Industrial and Manufacturing Engineering","volume":"4 ","pages":"Article 100075"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S266691292200006X/pdfft?md5=af6741fe2febd95adebb1324d527dd2c&pid=1-s2.0-S266691292200006X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47947600","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 portable UTM consists of a stepper motor, a load cell, a linear variable differential transformer (LVDT), a load cell amplifier and a data acquisition system. Copper based small and thin (50 μm) tensile test samples were tested on this machine at room temperature, and the calculated results were compared with the test results derived from a commercial UTM (METEX - 1 kN) to justify the validation of the developed apparatus. The obtained mechanical properties are in good agreement with the values obtained from a commercial UTM.
