Aimed at the contradiction between operational efficiency and resource losses, this paper defines a Meanwhile Combination and a Sequence Combination. The efficiency matrix is utilized to construct a model of the Meanwhile Combination, and the Dynamic Planning and Fuzzy Optimum Selection are utilized to construct a model of the Sequence Combination. In accordance with two optimization targets, i.e. the operational efficiency and the resource losses for battle plan or Meanwhile Combination at each stage, the paper calculates the comprehensive efficiency for each kind of the Sequence Combination. By so doing, this provides an important basis for selecting the attackdefense strategy on maximum comprehensive efficiency. The result shows that the strategy is conformed to the mission requirement and has a certain guiding role.
