Led digital transformation through the smart factory project
Currently, the manufacturing industry is improving operating efficiently, productivity and product quality and reinforcing safety by digitalizing the value chain and business environment and combining advanced technologies, e.g. 5G, AI, IoT and robots. Hankook Tire is conducting a project to improve the smart factory technology based on the data it has accumulated over the years through its operation of the tire manufacturing business, e,g. supply and demand of materials, design, R&D, production and distribution.
Hankook Tire R&D Center and production headquarters, in charge of the project, are using Tableau to quickly visualize vast amounts of data that are generated in seconds by the various factory facilities of Hankook Tire. They are aiming to use the Tableau dashboard to set apart the data necessary for smart factory applications, e.g. equipment maintenance, management and development, analyze the data through charts and logic, and create a data-based decision-making culture.
In particular, Hankook Tire R&D Center provided help with combining the AI technology with the model for predicting the physical properties of tire compounds by using Tableau to visualize the result of tire compound analysis in the Amazon environment.
Hankook Tire went a step further, and it is planning to create a system environment for quickly collecting and providing the data of global offices and factories and reinforce data interworking so that the headquarters’ innovation initiative and data standardization system can be expanded to its offices around the world.
Lee Gwang-won, G.IT Planning Team, Digital Strategy Department, Hankook Tire, said with emphasis, “Currently, the IoT and AI based smart factory is a hot topic in the manufacturing industry. As data analysis using Tableau makes it possible to find the insight necessary for improving the reliability and efficiency of manufacturing processes by integrating various kinds of data generated by smart factories, it is key to gaining top-tier competitiveness in the digital age.”
Provided support so that business departments can respond quickly to changes in external conditions
Before Tableau was introduced, at Hankook Tire, the data used for business decision-making and performance evaluation was not transparent due to the data silos of the system. In fact, as data was often deformed due to the supervision of frontline managers in the process of data retrieval, sorting and reporting, management diagnosis found that the demand for standardization of data and systematization of analysis has been rapidly increasing. Unreliable data was an obstacle to agile decision-making and responding to changes.
Hankook Tire is sharing business data in the report sharing portal of Tableau in real time so that business can be conducted based on more accurate data and analysis results in response to the quickly-changing business environment. In this portal, frontline employees use the Tableau maps or graphs to check Hankook Tire products and demand data of each region of the world.
In the past, as it used to take 8 hours to update the global inventory and sales data of Hankook Tire, it had difficulties responding to a crisis, but after adoption of Tableau, it is now possible to provide the data to employees in charge of marketing, logistics and sales in 30 minutes.
“To stably operate business in the rapidly-changing world, we must reduce and optimize costs,” said Lee Jae-sang, G.IT Planning Team, Digital Strategy Department, Hankook Tire. “We could use Tableau to enable frontline employees to share the sales and inventory data of our business operations around the world in real time, and expand the scope of available inventories from the sales perspective, and improve the resiliency of business.”
The management and financial management division introduced the Tableau dashboard and significantly reduced the reporting time, and they are planning to become the first to convert all Excel reports to Tableau.
