Effective factory production floor layout planning is essential for production management and requires careful consideration of multiple factors. This study proposes an industrial metaverse visualization approach for optimizing machine and workstation arrangement to improve production outcomes. This approach employs an algorithm to explore the feasible layout space, considering factors such as machine proximity, ergonomics, and production requirements. The resulting layouts are visualized in an industrial metaverse environment, allowing stakeholders to evaluate the impact before implementation. By leveraging industrial metaverse visualization, this approach eliminates the need for physical prototyping, reducing costs and risks associated with physical changes. A case study in a factory setting demonstrates the potential of industrial metaverse visualization, showing that it can improve floor space utilization, reduce cycle time, and enhance production efficiency compared to traditional manual methods. The study highlights the importance of visualization tools in facilitating decision-making and improving production outcomes, contributing to the growing body of literature on the use of metaverse visualization for industrial applications.
