Abstract: In order to solve the problems of low fitting and poor sensitivity of traditional methods, an evaluation method based on Choquet integral method is proposed for the economic benefits of intercity railway. Firstly, based on the frequency analysis results and expert scoring results, reliable indicators are selected from the pre-selection set of indicators, and then the advantages and disadvantages of each object to be evaluated are ranked according to the close value of the indicators. Then, the quadratic programming method is used to construct the objective function, the heuristic least squares method is used to determine the fuzzy measure of Choquet integral, and the final evaluation result is obtained after summarising the measure values of different nodes. Experiment shows that the evaluation sensitivity of this method can reach 0.98, and the maximum fitting degree of the evaluation results can reach 0.982, which indicates that this method achieves the design expectation.

Keywords: Choquet integration method; fuzzy measure; heuristic least square method; closeness value; quadratic programming method.
