Structural performance multi-target evaluation method

The invention discloses a structure performance multi-target evaluation method, and belongs to the related field of structure optimization and multi-target evaluation strategies. According to the method, evaluation is carried out by considering multiple performance indexes of the structure based on an evaluation function, subjective importance of each performance index on an evaluator and fluctuation of each performance index of the to-be-evaluated structure are comprehensively considered, and each index is weighted; an evaluation model construction form is adopted, the size of the weight can be fully reflected in a comprehensive evaluation result, the weight value is adjusted, the optimal structure obtained based on the evaluation index is changed accordingly, and the evaluation index meets the three-point requirement of reasonability. According to the method, the subjective weight is determined, the subjective importance proportion of each performance index on a researcher is reasonably quantified, and the
