摘　　要：从提升被评价对象竞争优势的角度对密度算子进行拓展研究,提出了竞争性密度算子的概念.首先,简要地介绍了密度算子,并给出了密度算子的具体表达式;基于此,给出了一种竞争规则,该规则分别从待集结信息的聚类和密度权重的确定两方面保证了被评价对象的竞争优势.最后,通过一个算例对竞争性密度算子的应用作了说明,并将其集结值与相应的已有集结算子的集结值进行比较,指出竞争性密度算子尤其适用于"偏才"或"怪才"的选取.The density operator was studied extensively from aspect of increasing evaluation object＇s competition advantage so as to develop the competition density operator.The density operator was firstly outlined and its general formula was given,based on which a competition rule was proposed.It can guarantee evaluation object＇s competition advantage from information clustering and density weights determining.A numerical example is given to illustrate the application of the competition density operator.The aggregation values of the competition density operator were compared with the existed operator,which shows that the competition density operator is especially suitable for strange talent choosing.
