Next generation military communication system (NGMCS) is described as a kind of typical information communication networks (ICN), and primary requirement and evaluation criterion of NGMCN architecture are summarized briefly. Then a general architecture model for NGMCN, composed of four sections, application, system, technology, and equipment, is set up based on vector space and Fuzzy Sets theory. Further the modeling method is presented with the discussions in detail on fuzzy sets and fuzzy relations associated with the architecture model.
