    Data Mining Approach in Repair and Service Systems of Electronic Products Under Warranty
    (Springer Science and Business Media Deutschland GmbH, 2022) Ersöz, F.; Merdin, D.
    The use and management of technology have an important role in increasing efficiency in the service sector. Especially in the electronics sector, which has a dynamic rate of change, technological support of service activities and big data have shown to enhance operational and tactical decision-making processes. In this way, efficiency can be increased by making faster and more accurate decisions in the organization. In this study, the researches covered technical service for the TV repairs in the electronics sector of Turkey by analyzing incoming data to create models and data mining techniques. This work is the only study in the literature aimed at contributing to operational processes by evaluating the only type of product in the electronic repair service sector using data mining methods relative to the type of repair. The results of the research are suggested to increase service efficiency and customer satisfaction from the feedback on sales and production processes with the proposed changes based on repair service information. © 2022, Springer Nature Switzerland AG.

    Evaluation of the Applicability of Industry 4.0 Processes in Businesses and Supply Chain Applications
    (Institute of Electrical and Electronics Engineers Inc., 2019) Merdin, D.; Ersoz, F.
    Increasing the flexibility and effeciency of enterprises from procurement to sales provides a great competitive advantage for meeting consumer demands. Providing competitive advantage is possible through the effective implementation of innovative technologies of fourth industrial revolution in the all stages of supply chain process. In this context, research has been carried out for industry 4.0 applications at every stage of the supply chain process and the role of digitalization in the supply chain has been mentioned. In addition, views and in-depth data from 32 companies based in Turkey were collected by questionnaire and subsequently analysed in a detailed format with data mining methods. In this context, using the augmented reality glasses in supply chain operations, the robots used in production can adapt more quickly to the works, especially in the logistics sector. Also, the use of drone has an important place in the external logistics processes. It was also observed that the use of autonomous electric vehicles can reduce harmful environmental impacts, thereby providing optimum vehicle routing. In summary, increase in digital data and the end of the life of the robots used in the development of robot resulted in huge data dumps; the small size and volumes of the firms' warehouses made it difficult to properly use robots; managers had troubles adapting their digital visions to the changing times and processes; employees experienced difficulties during transitions from one system to another; and finally, it is unclear whether the country's current energy capacity is sufficient for the growth of smart factories. © 2019 IEEE.
