In view of the problems in current equipment quality management, such as low prediction accuracy, incomplete data and insufficient interaction between virtual and real, the SWOT method is used to analyze the advantages, disadvantages, opportunities and threats of four strategic indicators of digital twin technology applied to equipment quality management. The weight of all strategic indicators is analyzed by analytic hierarchy process, (AHP) method, and the coordinate system of strategic intensity is constructed, and the SO-opportunity strategy is determined by the quadrant of its center of gravity, and the countermeasures and suggestions for the further development of the technology are put forward from five aspects. The results show that the analysis can provide a reference for the current equipment quality management.
