Study on air formation attack-to-ground decision-making in imperfect information based on rough set theory

As to characteristics of air formation attack to ground campaign, an air formation attack to ground command and decision making information system is presented. On the basis of rough set theory, the way of getting decision rules in imperfect decision information system is discussed, which is caused by the absent of data object and the value of condition attributes. The dependency of the rules is analyzed, and the dependable factor of the rules getting from the imperfect information system is calculated, which can provide a support to decision-making in campaign.
