ABSTRACTDue to the development of communication system in the warfare, the future warfare is changing to network-centric warfare (NCW). In the NCW, the communication effect has a significant influence on the combat power. There is growing importance for analysis of communication effect in the combat power. There are many researches about this issue, but there is no study on analysis using relationship between communication system and combat power. In this paper, we illustrates interoperation environment consisting of NetSPIN communication model and wargame model to analyze influence of parameters of communication model on combat effectiveness of wargame model. The wargame model is a corps-scaled model based on Discrete Event System Specification (DEVS) formalism. The communication model is a corps-scaled SPIDER network model of NetSPIN based on OPNET. Especially, we uses OAI matrix to identify parameters in communication simulator influencing on combat power, and analyze relationship between parameters and combat power through design of experiment and simulation by using them. For the future work, we expect that requirement analysis of communication equipment in NCW by using meta-modeling method
