In this study, efficiency increase refers to improving and maintaining high standards of demarcation, housekeeping, no blocked safety equipment, tools storage conditions, good manufacturing practices and chemical storage conditions. Using industrial engineering tools, Plan-Do-Check-Act and Kaizen, the study illustrates a quick turnaround in standards improvement in a manufacturing plant, which resulted in culture change and increasing profitability. The manufacturing plant studied had below average standards that created health and safety hazards leading to incidents, created a risk of quality and stewardship systems failure. Incidents varied from minor to serious. With improved standards, the plant avoided and eliminated health amd safety, quality, and stewardship risks in critical areas such as production or operations floor, warehouse, laboratory, storeroom, utilities area, and workshop. This was achieved through the integration of health and safety, quality assurance and stewardship controls as one safety, quality, and stewardship (SQS) framework. The three are denoted as fundamentals and core foundation systems in a manufacturing environment in this study. An SQS tool was developed, tested, and implemented and results are shared. Implementation of the tool resulted in improvement of overall manufacturing plant standards, elimination of safety hazards, reduction of quality defects and scrap, eradication of internal controls issues, and business success. The study will be of great value for manufacturing plants who are looking to integrate more than two management systems.","PeriodicalId":476696,"journal":{"name":"Reports in Mechanical Engineering","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134948145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional approaches to material selection typically involve an intricate interplay of multiple criteria, encompassing mechanical properties, environmental impact, cost, and availability. To grapple with this complexity, multi-criteria decision-making (MCDM) methods have risen to prominence as systematic frameworks for facilitating well-informed material selection decisions. MCDM methods offer a structured approach to evaluating and ranking materials based on a set of criteria, thereby empowering engineers and designers to make informed choices. In this paper, Measurement of Alternatives and Ranking According to Compromise Solution (MARCOS) method has been employed to determine the most suitable material for sintered pulleys used in automobiles. CRiteria Importance Through Intercriteria Correlation (CRITIC) method is applied to assign criteria weights. The analysis reveals that sintered hardened steel emerges as the best choice for sintered pulleys in automotive applications. To validate the outcomes obtained from the proposed method, a performance analysis has been conducted, comparing the results with those generated by other well-established MCDM methods. Additionally, a sensitivity analysis has been carried out using Spearman rank correlation coefficient.","PeriodicalId":476696,"journal":{"name":"Reports in Mechanical Engineering","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135482432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Complex production systems in rapidly changing environments result from product variation, shorter product life cycles, and supply chain expansion. A cyber-physical production system (CPPS) can use manufacturing and logistics data to plan, monitor, and control production. Discrete event simulation (DES) and digital twin (DT) technology can model and evaluate manufacturing and logistics processes using high-level decision support and process monitoring. The cost of collecting input data from different enterprise data sources and mapping it into models and the lack of qualified experts prevent the widespread use of these methods in industry, especially in small and medium-sized enterprises and larger multinational companies. This research aims to create a modular digital twin framework for manufacturing process optimization and real-time monitoring in an industrial environment with few components. The system can identify and track the product through the manufacturing cycle while updating the DT in real-time and can be used independently to collect input parameters for discrete event-driven simulations and even for automatic simulation building in the future. The framework's operation will be shown through an example. With the proposed IIoT (industrial internet of things) system integration, it can detect faults and warn of deviations from normal operation, and DT can drastically reduce data collection and model building and support model reusability, increasing sustainability.","PeriodicalId":476696,"journal":{"name":"Reports in Mechanical Engineering","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135393562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The successful formulation of a composite material is investigated by skillfully manipulating weight and quantity ratios. To achieve the desired outcome, different weight ratios of multi-walled carbon nanotubes (MWNTs), specifically 8g and 16g, are combined. Furthermore, these MWNTs are proportionately mixed with epoxy in volumes of 200ml, 400ml, 600ml, and 800ml, following a valence equation that correlates the gram ratio of MWNTs with epoxy. For the purpose of ensuring homogeneity and facilitating optimal component blending, an electric convector with a magnetic core is employed to generate vortices, aiding in the thorough mixing of the constituents. Subsequently, the mixture is hardened after proper placement. Prior to casting, the introduction of the hardener, whether in its liquid state or by incorporating reinforcement layers of carbon nanofibers (ranging from 0 to 16 layers), enhances and fortifies the desired properties of the material. The ingenuity of this approach is showcased by the exceptional results obtained from the evaluation of tensile stress and impact. Through rigorous testing and meticulous analysis, the findings validate the theoretical foundation upon which this endeavor is built, underscoring the success of this innovative concept.","PeriodicalId":476696,"journal":{"name":"Reports in Mechanical Engineering","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135393857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
