In the modern battlefield, various assets are interconnected in the land, sea, air, space, and cyber fields, and the cross-disciplinary battle takes place. In a defense equipment development phase, it is necessary for operational requirements to take a bird's-eye view of the entire connected system and clarify the mutual relationship. Japan Air Sel...

Architecting the system requirements is a critical task for systems engineering. This study is to implement Model-Based Systems Engineering as a trial to the concept Stage in the development of defense space system. Cross-domain operations require the construction of complex and extensive systems. This study validates the implementation of Model-Ba...

The use of outer space plays a vital role in both defense and civil fields. Since the separation of space activities between civil and defense applications is extremely inefficient, the Dual-Use concept has been considered fundamental for promoting the effective use of space. To the best of the authors' knowledge, most previous studies on Dual-Use...

The outer space utilizations play a vital role for both civil and defense fields. As for Japan, after the Basic Space Law was enacted, the new utilizations and R&D of space are promoted to enforce the national security. Under the circumstances, Dual-Use has become an important concept. However, the past studies were often focused on the technologie...

For large and complex systems, such as space applications, there exist several cases wherein civilian and defence stakeholders enable interoperability and data sharing with each asset. For this reason, there is concern that both stakeholders are hesitant to architect a dual-use system. This study aimed at optimization by searching for points where...
