Abstract: In order to verify the functionality of the FAO (full automatic operation) system, based on the DoDAF framework model, according to the characteristics of the FAO system, this paper built the FAO simulation system. The DoDAF framework model guided the design of FAO simulation system from requirements to detailed design. On the basis of completing the AV-1 requirement overview, CV-1 capability view and OV-1 preliminary design, the paper further designed the FAO simulation system by using the DIV-1 conceptual data model, OV-4 organizational relationship model, OV-5b combat activity model and bSV-1 model in detail.The FAO simulation system based on fine models data in Guangzhou line were finally implemented in laboratory and functions of the system were verified, which provided strong support for the engineering application of FAO system.
