Improvement on Attribute Weighting in Attribute Coordinate Comprehensive Evaluation Method

Attribute coordinate comprehensive evaluation method is essentially a qualitative evaluation method. Its feature lies in that on the same total score plane, on the basis of considering the comprehensive scores of all attributes, it focuses on considering the weight of certain attributes. The weight of an attribute is obtained by the evaluator's ratings, i.e. several samples are randomly selected from the hyperplane with the same total score for the evaluator to rate. However, the samples can be randomly selected and may not reflect all the characteristics of the entire attribute system, thus the ratings cannot reflect the evaluator’s preference well or the comprehensive factors of the attributes, further resulting in unreasonable evaluation results. This paper proposes a new attribute weighting method to fundamentally address this problem. Simulation experiments also verify the effectiveness of this method.
