“…All the convoy operations can be put in a larger fleet mission context that is the goal of the vehicle fleet. In this sense, a vehicle fleet as presented in Figure 1 can be considered a system of systems, commonly characterized as a system with individually operating subsystems and with emergent behavior as the system operates [ [7], [8]]. Systems of systems present inherent design challenges due to these characteristics, including the need to facilitate evolving functionality of subsystems over time and short development cycles to maintain system performance [9].…”

Modularity for ground vehicle systems has been viewed as a potential solution for the military to meet a variety of changing mission demands without keeping a large inventory of vehicles in a fleet. Defining the module concepts is a significant challenge that impacts the effectiveness of the modularity solution. In this paper, we propose a functional synthesis method to design a set of modules comprising a modular ground vehicle fleet according to overall fleet-level objectives. We start with a functional decomposition of a baseline conventional fleet capable of performing a given fleet mission. We then formulate a functional synthesis problem to draw the boundaries that define modules for a modular fleet having the same mission capability with maximum fleet performance defined by average weight of the fleet performing the required operations and personnel time to reconfigure and maintain the fleet. An example problem is included to illustrate the approach. Results show a trade-off between two fleet-level objectives with respect to the degree of modularity.

“…The US Department of Defense has recently increased its focus on methods of SoS design due to increased emphasis on integrating assets across forces and incorporating new technology to create multi-domain systems [18]. Multimodal transportation networks in the public sector are another example of SoS designs [19]. Many commercial product and service companies now invoke the SoS paradigm in moving toward integrated solution offerings.…”

Abstract. The contemporary environment and large-scale systems challenges motivate research in support of a new paradigm: value robustness. Value robustness is defined as the ability of a system to continue to deliver stakeholder value in the face of changing contexts and needs. The authors' research seeks to develop methods for concept exploration, architecting, and design using a dynamic perspective for the purpose of realizing systems, products, and services that deliver sustained value to stakeholders in a changing world. The research is aimed at improving the development of real world systems and systems of systems, and involves deep engagement with government and industry stakeholders in the research conduct and the transition of research outcomes to industry practice.

“…De Laurentis et al describe an SOS design approach based on intelligent agents autonomously exploring the design space to find an optimum equilibrium between the design parameters 4,5,6 . The approach they use seems to provide interesting results identifying some feasible space exploration architectures.…”

The design of complex systems has become more and more articulated during the last decade, thus forcing radical modifications on the overall methodological approach. The authors developed a design methodology, which allows the user to design a particular category of complex systems usually called System-of-systems. This paper discusses the general framework to deal with the decomposition of a system-of-systems in its elements and sub-elements, to enable a faster and more effective solution of the problem, extending the applicability of the Concurrent Engineering paradigm to design phases that go beyond the preliminary/conceptual one. A hypothetical space exploration architecture, with a rover system, a lander system and an Earth-Moon transfer mission, have been implemented and discussed, linking the elements of this particular System-of-systems with a non-hierarchical decomposition approach and a multi-disciplinary feasible formulation.
