Abstract: 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.

Key words: comprehensive evaluation, information aggregation, density operator, competition density operator, competition advantage, density weight
