An evaluation method was proposed based on combination assignment-objective element topable model. Firstly, the G1 method and entropy weight method were used to subjectively and objectively assign weights to the evaluation indicators, and the Lagrange multiplier method was applied to find the combination weights, which ensured the unity of the weights subjectively and objectively. As the qualitative index data was difficult to be calculated by the evaluation research, which affected the accuracy of the evaluation results to a certain extent, therefore, the object element topable model was introduced, and the topable set was token as a mathematical tool to realize the quantitative evaluation calculation and ensure the objectivity and accuracy of the evaluation results. Finally, the validity and practicability of the method is verified through the analysis of examples.
