HIDT: A Digital Twin modeling approach through hierarchical integration for industrial internet

Abstract

As the foundation of Digital Twin technology, modeling plays a pivotal role in the industrial internet. However, the research still faces significant challenges in modeling complex production lines. This paper presents a hierarchical modeling approach by integrating multi-dimensional scenes for a complex production line(HIDT). The construction process of each dimension model at different levels is modeled firstly. Then the connection and interaction rules between the models are defined. Finally, a clothing production line was taken to verify its feasibility. The results show that the method can avoid repetitive work in the construction process. The constructed model is more realistic and can collect data by classification, which provides help for data analysis
