Nippon Zeon Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President and CEO: Tetsuya Toyoshima, hereinafter referred to as Zeon) has partnered with SOLIZE Ureka Technology Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President: Hiroaki Tsutsumi) to achieve business reform through the formalization of plant design operations. This initiative aims to enhance efficiency and quality in plant design, which is crucial for stable and safe production, thereby strengthening competitiveness. It is also expected to contribute to the development of next-generation talent by facilitating the transfer of know-how from experienced employees. Amidst business expansion and increasing sophistication of facilities, improving the efficiency and quality of plant design operations, essential for stable and safe production, has long been a major theme for Zeon. One such area is the creation and review of P&IDs (Piping and Instrumentation Diagrams)*, which are extremely important in chemical plant design. P&IDs are fundamental documents for engineering, from design and construction to operation and maintenance. Their creation requires advanced knowledge and experience, posing challenges in terms of personalization and knowledge utilization. To address this, Zeon and SOLIZE Ureka Technology have visualized the processes involved in these operations and built a system that organizes tacit know-how into linguistic data. This system goes beyond mere data accumulation; by defining the formalization of usable know-how, it enables designers to instantly grasp necessary information at a glance. Furthermore, to ensure the continued utilization of the developed design know-how assets in the future, a platform focused on designers' ease of searching has been established, enabling rapid data retrieval. This allows for the accumulation of explicit knowledge as organizational assets, leading to effects such as improved operational efficiency and design quality.
