Specifying system requirements (SysReqs) is a critical activity in complex systems development. The SysReqs and emerging architecture are constructed through gradual and iterative transition from the problem domain and operational stakeholder requirements to the conceptual solution domain. They later constitute the basis for functional requirements elaborating, concept formation, technology selection,...
In the twenty-first century, mission success will require unprecedented interoperability among disparate constituent systems resulting in a System of Systems (SoS). Unlike traditional systems engineering where systems are created based on a set of user needs, a SoS is composed of multiple constituent systems, at various stages within their lifecycles (i.e. new start systems, systems in-development,...
Combat system effectiveness simulation (CESS) is a special type of complex system simulation. Three non-functional requirements (NFRs), i.e. model composability, domain-specific modeling, and model evolvability are gaining higher priority from CESS users when evaluating different modeling methodologies for CESS. Traditional CESS modeling methodologies are either domain-neutral (lack of domain characteristics...
System of Systems Engineering (SoSE) and Family of Systems Engineering (FoSE) continue to be two of the least well-understood SE disciplines. Knowledge of the SE standards, the V-Model, and particularly the 3-dimensional dual-V model, significantly aid this understanding, including the relationship between SE, SoSE, and FoSE. The goals of this paper are to: 1) define SoS, SoSE, and FoSE from an SE...
