According to the characteristics of the collaborative combat formation, appling to the analytical hierarchy process puts forward the formation of the overall operational effectiveness evaluation index system. The key of the researches are factors that influence the overall operational effectiveness formation, such as the penetration ability, attack ability, interoperability and command decision-making ability and establish the evaluation model. Then in-depth analysis of the influence conditions of each factor and calculate the standard layer in the weighting coefficient of various factors. Finally it is proved that the evaluation index system of rationality effectively by examples of demonstration. For the collaborative attacking formation of assessment operational effectiveness provides the effective theory basis.
