Abstract: A method based on dynamic influence nets(DINs) which models the course of actions(COA) problem of command and control(C2) organization was proposed. In this method,the causal strength parameters arc introduced instead of conditional probability tables,and the probability propagation algorithm using causal strength parameters was presented. At last,the superiority and efficiency of this modeling method was illuminated by a case of joint campaign.

Key words: C2 organization, Course of actions, Dynamic influence nets, Causal strength, Dynamic Baycsian networks
