摘要
针对群体评价中专家信息的集结问题,从利益相关者协商的视角对密度算子进行拓展并将其用于解决该问题.协商的基本思想是使协商值与单个协商参与者(或利益集团)给出的协商信息偏差最小.在此基础上,基于密度算子信息集结的过程,结合着组内和组间信息的特征,分别给出了组内和组间协商的两种模型,以此实现信息的集结.最后,通过一个算例对该方法的应用进行了说明.该方法的研究可进一步完善密度算子的理论体系并拓展其实际应用范围.
To solve the problem of information aggregation in group evaluation,density operator was researched and used from the aspect of stakeholder negotiation.The basic idea of negotiation is to make a minimum deviation between the negotiation value and the negotiators' values.Based on this,combing the density operator process with the feature of the same and different group,two types of negotiation models were provided to aggregate information.At last,a numerical example was given to illustrate the using of this method.This research could further perfect theory system of density operator and extend its application range.
