Abstract: In allusion to the shortage of traditional alternation measure in combat repertory material alternation, from the point of important degree of material, a method of combat repertory material alternation based on principal component clustering analysis is proposed. The shortage of traditional measure and character of material management are comprehensive considered, the paper builds a new index method. Base on the new index, principal component analysis method is used to reduce dimensions, and hierarchical clustering method is used to clustering analysis. At last, base on the outcome, the right alternation measure is used. The simulation proves that the result is effective and reasonable.

Key words: principle components analysis, clustering analysis, combat repertory material alternation
