Description

Digital twin-based factory facility automatic placement system and method The present invention relates to a digital twin-based factory equipment automatic placement system and method. The existing design method for arranging multiple factory facilities within a factory with limited space is as follows. First, the process is planned, and target production volumes are determined. Then, layout design for production and logistics facilities is performed using CAD software. This process involved excessive manual work and made collaboration impossible. Additionally, calculating layout optimization KPIs manually created a potential for errors. Subsequently, layout issues were discovered during the process of installing factory equipment and producing goods based on the layout design results. In such cases, redesigning the layout incurs enormous costs; consequently, if the problematic layout is utilized without redesign due to these cost concerns, it leads to increased logistics costs and decreased productivity. The matters described in the technical background section of this invention are for the purpose of understanding the background of the invention and cannot be concluded as prior art already known to a person with ordinary knowledge in the field to which this technology belongs.
