With the development of information technology, the role of information superiority in combat command is becoming more and more prominent, but the traditional index system can not meet the system evaluation under the informationization condition; therefore, based on the characteristics of operational command and control system and the traditional index system, this paper integrates the information advantage with the evaluation index system to construct a more realistic evaluation index system. In addition, on the basis of reading a large number of references and in combination with the actual system, a quantifiable mathematical model was established for each evaluation index to sum up the three points in index system construction process. Finally, the correctness of the index system is verified by simulation experiment.
