A construction Method and Application of Judgment Matrix under the Condition of Mapping

Abstract:
The traditional method of constructing judgment matrix is generally scored by experts. There must be some problems, such as strong subjectivity, difficult to determine the value and low consistency. In this paper, a method of subjective and objective fusion to construct judgment matrix is proposed, which mainly constructs the mapping conditions from relevance to importance, establishes the mathematical model, calculates the approximate element values of the matrix, and then subjectively maps the approximate element values to the scale of 1-9, so as to construct a new matrix. Finally, the method is applied to the weight calculation of factors affecting automobile price evaluation for verification and analysis. The experimental results show that this method can not only construct a new matrix with the advantages of numerical determination and high consistency, but also make a fuzzy evaluation of the decision results, reflecting the mathematical innovation and economic value of this study.
