以评价者为节点,评价者之间偏好相似性测度为连接的网络为群体偏好网络,讨论了评价群体在偏好网络均衡状态时3种不同网络结构(星形网络、闭链结构和完整网络)的群体评价信息集结方法,将具有网络结构信息的节点数据转化为平面数据,提出了平面密度加权平均算子和平面密度加权几何平均中间算子。给出了平面数据的划分方法及平面密度算子的趋同性测度,并将算子应用于各网络结构的评价群体评价问题。
Under certain condition,different evaluation groups have certain connection and the nodes and links corresponding with the experts and their relations.We discuss the problem of the network of star,cycle and complete structure with equilibrium and the method of group information aggregation.The panel data from node data,and the panel density weighted averaging(PDWA) operator and the panel density geometry averaging(PDWGA) operator are developed.Moreover,the method regarding how to divide the panel data is given for group evaluation.
