![]() ![]() Our research demonstrates that while ICT has evolved quickly, solutions that attempt to identify issues and model large complex networks have failed to evolve at the same pace. As a result, systems-of-systems (SoS) are failing directly owing to these significant risk elements. Furthermore, they are extremely rigid, focusing upon a specific risk, attack, vulnerability, and are industry specific. ![]() Current solutions are inadequate, and incapable of adapting to the scale and complexity of these infrastructures. ![]() The rapid integration and dependence upon information and communication technologies (ICT) within varying industries, has augmented cyber interdependencies along with increasing other elements of risk such as complexity, cascading failure and single points of failure within collaborative infrastructures. Our analysis shows that the querying and composition capabilities of the RDL pro- vide valuable support for reasoning across documentation of multiple systems and specifying suitable integration constraints. We showcase the capabilities of our RDL through a case study of a real-world emergency response system. The aspect-oriented compositions in the RDL also facilitate specication of cross-document constraints and inconsistency resolution strategies, which can be used for deriving proof obligations and test cases for verication and validation of the emergent behaviour of a system-of-systems. We then present an aspect-oriented requirements description language (RDL) which uses natural language analysis capabilities to reason about dependencies across the documentation of the constituent systems of a system-of-systems. In this paper, we focus on three ma- jor classes of system-of-system integration problems: managerial inde- pendence, interface incompatibility, and component-system complexity. A num- ber of factors can make this integration very challenging which often leads to catastrophic failures. Systems-of-systems are formed through integration of indi- vidual complex systems, often not designed to work together. ![]()
