A Research Agenda for Systems of Systems Architecting

Abstract

This paper, documents the activity of a workshop on defining a research agenda for Systems of Systems SoS; Architecting, which was held at USC in October 2006. After two days of invited talks on critical success factors for SoS engineering, the authors of this paper convened for one day to brainstorm topics for the purpose of shaping the near-term research agenda of the newly convened USC Center for Systems and Software Engineering (CSSE). The output from the workshop is a list of ten high-impact items with corresponding research challenges in the context of SoS Architecting. Each item includes a description of the research challenges, its link to contemporary academic or industrial problems and reasons for advocacy of that area. The items were assessed in terms of value and difficulty to determine a prioritisation both for the CSSE's future research agenda and for others in the field.

11.2.2 A Framework for System Resilience Discussions

“…When the view is thus widened, it becomes clear that the larger parts can also be described as resilient (or not). -of-systems [Resilience Alliance, 2007] [Axelband and Valerdi, 2007], exhibit resilience by continuing to collaborate and presumably by continuing to evolve. Ecosystems (e.g.…”

“…Next Prev First [Jackson, 2007] Ability to mitigate the severity and likelihood of failures or losses, to adapt to changing conditions, and to respond appropriately after the fact. [Axelband and Valerdi, 2007] The attribute of a system of systems that makes it less likely to experience failure, and more likely to recover from failure. [Woods, 2006] Resilience is how well a system recognizes and adapts to handle unanticipated perturbations (those perturbations that are outside the design envelope) [Westrum, 2006] Resilience is 3 things: 1.…”

Defining and Researching “Dynamic Systems of Systems”

“…It abstracts from the scope of engineered systems, like small vertical dynaSoS or large dynaSoS. Papers specifically focusing on architectures are presented in [81][82][83][84][85][86][87]. Our focus is broader, as we consider research fields related to properties of dynaSoS.…”

SoSML: Rumo a uma Linguagem de Modelagem Arquitetural para Sistemas-de-Sistemas Intensivos em Software

“…Por outro lado, a engenharia de SoS enfrenta desafios importantes devido às suas características e complexidades inerentes [Axelband et al 2007]. O principal problema é que a Engenharia de Sistemas Baseada em Modelos utiliza como referência ADLs tradicionais (UML e SysML) concebidas para descrever a arquitetura de sistemas de software isolados (não múltiplos).…”
