Fuzzy Reasoning Model and Calculating Method for the Sellers' Credit of C2C Based on the Evaluating Indexes of Taobao Net

Abstract

Aiming at the limitation to the credit evaluating system of C2C, a multi-variables fuzzy reasoning model is constructed and the calculating scheme is designed to evaluate the sellers credit of C2C referring to the evaluating indexes of Taobao net. The score of credit indexes is defined by the form of continuous interval in the model based on the interdependent relationship between the global assessment and the secondary evaluation indexes. Since the effect of the subjective factors on credit rating is efficiently eliminating in the algorithm and the credit description is more close to the transaction fact, the rating results of credit got by fuzzy calculation is more reliable than the ones obtained by traditional evaluation method. To verify the effectiveness of the fuzzy method, an applied example is given under the background of Taobao transaction.
