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。Combined with big data to evaluate network integrity of the seller, process, evaluation weightsselected dimension conflict problem in mathematical modeling. Based on binary group four dimensionalweight constraint mathematical model for the evaluation of individual integrity. Time in evaluating onlineseller from the buyer, the reliability of the transaction, buyers, fraud penalties four dimensions, etc withthe constraint of the dynamic weight, in order to avoid conflict dynamics, the weight of the fourdimensions to binary set of constraints, in the case of conflict, can make regression mathematical model,implements the conflict- free assessment in the integrity of e- commerce sellers. After test using thismodel to evaluate the integrity of e-commerce sellers, reasonable weight distribution, and have applied.
