【摘要】：结合大数据对网络卖家的诚信度进行评估过程中,评估权重选取在数学建模中存在维度冲突的问题。提出基于二元组四维权重约束的个体诚信评估数学模型。对网络卖家来自买家的评价时间、交易金额、买家的信誉、交易欺诈惩罚等四个维度赋予带有约束的数学动态权重,为了避免动态性带来的冲突,将这四个维度的权重进行二元组约束,在发生冲突的情况下,数学模型可以做出退行约束,实现了对电子商务卖家诚信度的无冲突评估。测试后得出利用该模型进行电子商务卖家的诚信度评估,权重分布较为合理,具备应用性。
[Abstract]:In the process of evaluating online sellers' credibility with big data, the problem of dimensionality conflict in mathematical modeling exists in the selection of evaluation weights.This paper presents a mathematical model of individual integrity evaluation based on the four dimensional weight constraint of binary group.The evaluation time, transaction amount, buyer's reputation and transaction fraud punishment of online sellers are given mathematical dynamic weight with constraints, in order to avoid the conflicts caused by dynamic, the paper puts forward four dimensions of online sellers' evaluation time, transaction amount, buyer's reputation, transaction fraud punishment and so on.The weights of these four dimensions are constrained by binary groups. In the case of conflict, the mathematical model can make retreat constraints, and realize the non-conflict evaluation of the trust of e-commerce sellers.After testing, it is concluded that the weight distribution is reasonable and applicable.
