Deriving the difference between the assumable ranges depending on virtual System-of-Systems (SoS) and invisible SoS

Abstract

The previous study states needing to confirm whether systems designers and systems engineers can applicate in other fields the architecture description method that clarifies the objects to reduce misunderstanding of the scopes of virtual system-of-systems (SoS). In order to confirm applicate in other fields, we concretely applicate the previous architecture description method to the case both including virtual SoS and invisible SoS. Especially, we try to clarify the difference between the assumable range depending on virtual SoS and the assumable range depending on invisible SoS. We consider that the systems engineers and systems designers can expand the two assumable ranges using the previous architecture description method. In the evaluation method, we show the assumable range depending on virtual SoS and the assumable range depending on invisible SoS. Next, we show the difference depending on virtual SoS and invisible SoS. Finally, to verify the difference, the three writers that understood the previous architecture description method confirmed the results. As results, we suggest to depend on the position and contractual relationship with the visible one, in order to hear the relation of virtual SoS. However, we consider hearing the relation of invisible SoS more difficult than hearing the relation of virtual SoS. The reason why we consider it difficult is that the relation of virtual SoS is direct, and the relation of invisible SoS is indirect. From the above, we showed the difference between the assumable range depending on virtual SoS and the assumable range depending on invisible SoS. Finally, this study concludes with future research topics.
