Novel credit rating method under electronic commerce

To improve the level of credit rating under the condition of electronic commerce,a comprehensive credit index system is established,and a scatter-degree(SD) based fuzzy comprehensive evaluating(FCE) method(SD-FCEM) is proposed.In SD-FCEM,the conventional SD method is adapted,which is applied to determine weighting coefficients of the rating indexes.Thereby,the FCE method is adopted to fuse every index values.The result shows that SD-FCEM can magnify the credit distance among varied electronic commerce subjects,thus the credit mechanism-based competition effect can be obtained under the condition of electronic commerce.The SD-FCEM is adapted to the condition that the distance among evaluated subjects needs to be enlarged.
