Abstract: Net centric simulation runtime support platform(NCS-RSP) provides an environment supporting the construction of community of simulation task(CoST). This paper adopted dual software architecture description framework XYZ/ADL to describe the architecture of NCS-RSP by graphics language and formal language respectively. Then we decomposed and refined the core service layer during the construction of CoSt.This description method not only expresses the architecture graphics and behavioral abstraction of NCS-RSP from visual viewpoint, but also validates the corredness and completeness of architecture design from formal view. The research is a new attempt of formal description in military simulation domain and it provides a guide for the composition and reuse of NCS-RSP service.

Key words: Net centric simulation, COST, Runtime support platform architecture, Architecture description language,XYZ/ADL
