A Method of Multi-attribute Decision Making Based On Basic Point and Weighting Coefficients Range

To solve multi-attribute decision making problem of limited schemes, multiple attribute indexes is generally synthesized to a single evaluation index. So it is necessary to determine the weighting coefficient of each attribute index. In this paper we propose a method of multi-attribute decision making based on basic point and weighting coefficients range. Weighting coefficient of each index may be calculated with the method in this paper, provided weighting range of each index, basic point and its comprehensive evaluation value are given. The method not only involves the subjective estimating of the people, but also avoids the comparison and evaluation between various attributes. If comprehensive evaluation value of basic point is difficult to determine, one can give a probing value, modify the value gradually until satisfying consequence is obtained.
