ABSTRACT=In the context of digital public health, this study tackles challenges in prioritizing the replacement of large-scale medical equipment, such as limited data for decision-making, subjectivity, imprecision, and complex allocation of indicator weights. A multi-criteria decision-making model for the replacement of medical equipment based on the COWA-PCA weight and GRA-TOPSIS method was established in this study. Through the analysis based on the construction of a priority evaluation system for the replacement of large medical equipment, the combined weight values were determined using game theory by combining the weights obtained by the COWA method and the weights obtained by the PCA method. The method of grey relational analysis was also used in combination with the TOPSIS method. The MRI equipment of a tertiary hospital was used as an example for validation and to determine the optimal update priority order of the equipment. The results indicated that the ranking results were consistent. In contrast to the stand-alone GRA and TOPSIS methods, the proposed model showed the highest degree of discrimination, which provides a solid decision basis for the optimisation of large medical equipment replacement strategies.
