The Engineering Systems (ES) movement set a research agenda that transformed the field of systems engineering. By focusing on complex sociotechnical systems, the ES movement dramatically expanded the scope of the problems that could be addressed by systems engineers, drawing young scholars into the field. ES succeeded in focusing the scholarly community around the concepts of the "ilities"-nontraditional system lifecycle properties-sociotechnical complexity, and system architecture. In this article, I review some of the progress made by scholars in the field, outline directions for future work, and identify challenges facing future progress in systems engineering. Specific attention is given to approaches that emphasize the roles of abstraction hierarchies, contextual interpretation, knowledge sharing, and expertise. I also briefly address the perceived trade-off between academic rigor and practical utility-a perennial concern in the field. In each case, a review of the literature is performed documenting the progress made by the ES community and other scholarly communities whose findings may be synergistic with ours. Finally, I conclude with a proposal for preserving the momentum started by the ES movement by suggesting a forum for diverse scholarly discourse in systems engineering.

“…Since many stakeholders are invested in the system throughout its life cycle, these ‐ilities should be evaluated over the entire mission life cycle for assessing performance and to help identify risks for each stakeholder. Guariniello developed an approach involving integrated analysis of system dependencies to quantify and compare ‐ilities for system of systems based on fundamental network analysis concepts 17 . The author emphasized that the approach serves as an initial process toward a full analysis and quantification of desired metrics for system of system development, and we believe that this can be extended to CASs due to similar needs of understanding emergent behavior.…”

A stakeholder framework for evaluating the ‐ilities of autonomous behaviors in complex adaptive systems

Complex adaptive systems (CAS) exhibit emergent behaviors caused by the nonlinear actions between individual components within the system and their environment. These emergent behaviors are difficult to predict and measure making it very challenging to initially design from the start. Developing CASs, such as an autonomous swarming unmanned system, is a relevant key task today for solving hard problems with limited resources in a demanding economy. Swarming unmanned systems are valued by their unique capabilities, but how do stakeholders ensure their needs are considered during development? Certain stakeholders have interests that go beyond the initial delivery of the system, yet developers seem to focus efforts on designing autonomous behaviors to satisfy immediate mission needs. To close this gap, we propose a stakeholder focused framework for evaluating CASs over a full system life cycle for swarming unmanned systems. A goal‐oriented requirements engineering modeling methodology, Knowledge Acquisition in AutOmated Specification, is used to map requirements between stakeholder goals and autonomous behaviors. Behaviors are analyzed in an agent‐based simulation using NetLogo for quantifying stakeholder‐driven performance qualities (‐ilities). A case study was performed for a swarm of unmanned surface vessels called wave gliders to evaluate performance over the entire system life cycle.

“…In a typical SoS, CSs are autonomous, which turns the SoS architecture to be inherently dynamic. SoS dynamic architecture makes the SoS assume several different architectural configurations (also known as coalitions), which brings (i) a non-deterministic nature to it due to addition, deletion and updates in CSs at runtime, and (ii) high degree of unpredictability, which potentially impact SoS functional and non-functional properties [7]. Hence, despite being a complex and difficult task, modeling these stochastic dynamic architectural changes early in the life cycle at SoS abstract level becomes a prominent endeavour.…”

Systems-of-Systems(SoS) result from the collaboration of independent Constituent Systems (CSs) to achieve particular missions. CSs are not totally known at design time, and may also leave or join SoS at runtime, which turns the SoS architecture to be inherently dynamic, forming new architectural configurations and impacting the overall system quality attributes (i.e. performance, security, and reliability). Therefore, it is vital to model and evaluate the impact of these stochastic architectural changes on SoS properties at abstract level at the early stage in order to analyze and select appropriate architectural design. Architectural description languages (ADL) have been proposed and used to deal with SoS dynamic architectures. However, we still envision gaps to be bridged and challenges to be addressed in the forthcoming years. This paper presents a broad discussion on the state-of-the-art notations to model and analyze SoS dynamic architectures. The main contribution this paper is threefold: (i) providing results of a literature review on the support of available architecture modeling approaches for SoS and an analysis of their semantic extension to support specification of SoS dynamic architectures, and (ii) a corresponding taxonomy for modeling SoS obtained as a result of the literature review. Besides, we also discuss future directions and challenges to be overcome in the forthcoming years.
