Abstract: In order to deal with new combat concepts such as distributed warfare, mosaic warfare, and cross-domain warfare, and then to address the dynamic generation of cross-domain combat system-of-systems, an architecture modeling method is proposed from viewpoints including tasks, capabilities, activities, services, and information resources. With this modeling framework, a system-of-systems developing approach is put forward, based on capability package and combat resource discovery. The above modeling framework and generating method helps develop cross-domain solutions and form joint forces.
