【摘要】：結(jié)合大數(shù)據(jù)對網(wǎng)絡賣家的誠信度進行評估過程中,評估權(quán)重選取在數(shù)學建模中存在維度沖突的問題。提出基于二元組四維權(quán)重約束的個體誠信評估數(shù)學模型。對網(wǎng)絡賣家來自買家的評價時間、交易金額、買家的信譽、交易欺詐懲罰等四個維度賦予帶有約束的數(shù)學動態(tài)權(quán)重,為了避免動態(tài)性帶來的沖突,將這四個維度的權(quán)重進行二元組約束,在發(fā)生沖突的情況下,數(shù)學模型可以做出退行約束,實現(xiàn)了對電子商務賣家誠信度的無沖突評估。測試后得出利用該模型進行電子商務賣家的誠信度評估,權(quán)重分布較為合理,具備應用性。
[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.
