Abstract

The recent trend in the war fields on the globe may be characterized by the network-centric warfare, whichwould, in turn, make the concept of weapon systems be changed. To this end, the concept of system ofsystems (SoS) has been introduced in literature. An SoS is a collection of multiple systems, each of which isan independent system and can be interoperable with each other. Thus, in defense domain each SoS is a bigweapon system as a whole operated in actual environment and each element of it is also an independentsmaller weapon system, but they should be interoperable via network among each other. The safety resultsstudied for each elementary system alone may not be fully applicable to the whole SoS. As such, the objectiveof this paper is to study how to make the SoS safety requirements be distributed down over the interoperableelementary systems. Since handling the interoperability requires a technique of systems architecture, a standardmethod called the DoD Architectural Framework (DoDAF) has been used here to derive a solution. UsingDoDAF, the safety requirements were first analyzed in the operability environment. The results were thenstudied to be included in an integrated model of both the systems design and safety processes. A further studyof present paper would facilitate ensuring safety in the development of SoS weapon systems in practice.
