Digital twin is an enabling technology of smart manufacturing. The core of the manufacturing is the shop floor, where the digital twin shop floor (DTS) is applied to facilitate its intellectualization. DTS enables the high-fidelity mapping for physical shop floor and provides intelligent services. However, the high-fidelity mapping of DTS requires modeling from multiple dimensions. In this paper, the geometric modeling of the DTS is conducted based on model reuse first. Next, the behavior modeling of equipment production in DTS and DTS production process is performed. Then the DTS service of the abnormality handling is derived. Finally, an aerospace product assembly shop floor is chosen to verify the proposed procedures and methods.
