During the gemba walk, VAA and NVAA were recognized, and their percentages indicated as 38,19 and 61,81 respectively. During the 5S Audit, particularly in the assembly kits, unnecessary materials were found, some necessary parts could not be found and there was no order in the assembly kits. The consequences of this situation can be summarized as follows: an excessive amount of time was spent distinguishing the necessary parts. Employees had to go to other workstations or warehouses to bring the necessary parts. Additionally, sometimes disorder of assembly kits resulted in overprocessing because they were open to mistakes and confusion. Besides, the types of the Muda’s monitored in the line were inventory, movement, waiting, overproduction, and overprocessing. Based on cycle time measurements, it was seen that motion and inventory- lack of 5S were the major wastes with percentages of 76,62 and 12,14. Mainly, two essential wastes were focused and the A3 problem-solving method was implemented. It was suggested that assembly kits and the line itself should be checked, and only necessary materials with the desired amount should be placed, all others should be removed. Assembly kits should be prepared for only 1 part of the main product. The other suggestion is to apply of Kanban Logistics system in the firm. With the help of these two main applications, it is predicted that employees' attention and motivation will be enhanced, quality issues will be minimized, cycle time will be reduced, and productivity of the line will be increased. As a result, NVAA will be less and VA will be higher, based on these, customer satisfaction and company profit will be promoted.Tétel Szabadon hozzáférhető Research on Optimization of Product R&D Project Management of Company M Based on Lean ManagementJIANG, HUAYU; Mátrai, Norbert Zoltán; DE--Műszaki KarThis article takes the practical learning of Company M as a case and the company's product R&D process management as the research object.

This thesis examines the impact of industrial robotics on EU economies by investigating the relationship between robotic adoption and macroeconomic indicators, including GDP per capita and the unemployment rate. The study uses a panel dataset, which covers EU member states over the past two decades. Using regression and time-series analyses, I have built a fixed-effects multiple regression model and an autoregressive distributed lag model, respectively. The research results verify the hypotheses of positive relationships of robotic installations with GDP per capita, and the unemployment rate. Findings suggest a significant positive and long-term impact between robotics and economic growth, with evidence of wide deployment in various industries, including automotive, electronics, logistics, and more. However, the analysis reveals a negative short-term impact on employment, which can be explained by job displacement and new skill requirements after technology-driven structural changes in manufacturing and production processes. The impact of industrial robotics on macroeconomic indicators goes beyond the theoretical and practical implications. Such automation technologies shape the economies of the EU, and this study contributes to understand the extent of the impact by providing insights for policymakers and industry stakeholders.Tétel Szabadon hozzáférhető Integrating Project Management Techniques to Optimize IT System Development and Resource AllocationBerdiugina, Anastasiia; Matkó, Andrea Emese; DE--Műszaki KarRobotic Process Automation (RPA) enhances organizational procedures by using software robots to interact with human interfaces, bypassing standard programming methods. The RPA project on automation of the process of archiving electronic documents was used as the object of the study. This project aims to simplify the employee's work, specifically releasing their working hours. However, during the implementation phase, problems were identified that affected the inefficient allocation of resources. In this paper, problems have been identified and metrics have been implemented to assess the quality of the system. As a solution, the use of project management practices was proposed, in particular risk management methodology. By comparing the metrics of each version of the system, it was found that the use of project management significantly improves the quality of the IT system being developed, reduces development time, and increases user satisfaction.Tétel Szabadon hozzáférhető Intercultural organizational communication: an overview in Multinationals in HungarySouza Sampaio, Mariana; Diószeginé Zentay, Éva; DE--Műszaki KarThis paper aimed to further both theoretical understanding and real-world understanding of the integration of recent immigrant workers into Hungarian businesses. The multinational companies in Hungary can fully utilize their workforce, cultivate an inclusive, innovative, and collaborative organizational culture, and guarantee employee retention and satisfaction by comprehending the viewpoints of their workforce and tackling the obstacles related to international onboarding and intercultural organizational communication. In view of the literature review and analysis of the data collected by surveying the international workers in the Hungarian companies, it was possible to observe that, although the Human Resources Management department in these organizations has implemented many actions to improve the internal communication and insertion of these employees, the complete inclusion is not yet achieved. With this research, it was possible not only to have an understanding on the perception of the international workers in Hungary, but also to have valuable insights for developing strategies that facilitate the seamless integration of foreign employees, ultimately contributing to the success of multinational operations in Hungary.Tétel Korlátozottan hozzáférhető Analysis of the Impact of Lead Time Reduction on Inventory Management in the Adhesives Business of a Chemical CompanySilva Garcia, Amanda; Sipos, Csanád; DE--Műszaki KarSummary The purpose of this thesis was to investigate the significant role that supply chain management (SCM) and innovative business models play in enhancing the competitive advantage of businesses, with a specific emphasis on the adhesives industry. The research includes an in-depth analysis of inventory management and lead time reduction strategies, with the purpose of determining the impact that these strategies have on the efficiency of operational procedures. The research was carried out within the adhesives department of a chemical company, with a particular emphasis on four distinct assets: two, which were produced by the company itself, and two, which were manufactured by third-party companies. The primary goals were to evaluate the efficiency of the initiatives that were implemented to reduce lead times and to comprehend the impact that these initiatives had on inventory management and the overall efficiency of the supply chain. Using advanced analytical tools, as Microsoft Excel and SAP, it was possible to gather a broad understanding by combining qualitative and quantitative approaches, as well as by utilizing data from enterprise resource planning (ERP) systems. The results of the study showed that strategic interventions, as changing materials from Make-to-Order (MTO) to Make-to-Stock (MTS) strategy and optimizing production windows, resulted in a significant reduction in Total Replenishment Lead Time (TRLT). This reduction demonstrated that there is a direct correlation between improved inventory management and shorter lead times. Consequently, these enhancements highlight the efficacy of strategies that aim to reduce lead times, which in turn reduce inventory levels, free up capital, and reduce the costs associated with storage. It's know that when improving lead times and inventory management, there is also a gain in service level, however was not possible to show the improvement in the thesis, for that it would be necessary to have some specific past data from the company related to service level, which wasn't possible. Implementing advanced enterprise resource planning (ERP) systems and planning tools, like SAP, was also a key part of making supply chain activities run more smoothly. Being able to quickly adjust to market needs was made possible by cutting down on lead times and improving inventory management. This made the company more operationally agile. In the fast-paced and competitive global market we live in now, this change in responsiveness is necessary to stay ahead of the competition between companies.Tétel Korlátozottan hozzáférhető Improving Valve Industry Demand ForecastingBautz da Penha, Milena; Sipos, Csanád; DE--Műszaki KarThe thesis examines various quantitative forecasting techniques to enhance demand prediction in the valve industry. Analyzing historical sales data for five Flowserve products, the study employs methods such as Simple Average, Moving Averages, Exponential Smoothing, Holt-Winters Method, Linear Regression, and ARIMA. The performance of these techniques is evaluated using Mean Absolute Error (MAE), Mean Squared Error (MSE), and Mean Absolute Percentage Error (MAPE). Results indicate that sophisticated models like ARIMA and Linear Regression outperform simpler methods by better capturing data variability and trends. The findings suggest that advanced forecasting techniques are essential for improving inventory management and operational planning in the valve industry, offering valuable insights for industry practitioners and contributing to the broader field of demand forecasting research.Tétel Szabadon hozzáférhető Business Feasibility Study for the Establishment of Building Materials Business in Freetown, Sierra Leone.Kuyateh, Ibrahim; Jenei, Tünde Katalin; DE--Műszaki KarFreetown's building materials market suffers from low-quality standards, leading to adverse effects such as inflation and delayed deliveries.
