Managing the evolution of independent or loosely coupled systems of systems (SoS) is difficult. Much of the difficulty resides in the ways that elements are combined to make up the SoS and how those elements interface. The Systems Engineering Research Center has been studying how new governance mechanisms drawn from agile, lean and other adaptive approaches could be applied to systems of systems engineering. One of the current tasks is developing a broad, general purpose simulation platform designed to investigate how various combinations of organizational structure, work flow, and governance mechanisms affect the visibility, flow, and overall value produced in developing and evolving SoSs.

GPS systems have revolutionized the way people and social networks in society interact. As GPS becomes more ubiquitous in road transportation, energy, or autonomous delivery drones, there is increasing opportunity for adversaries and malicious attackers to exploit GPS infrastructure so as to hijack or damage position-sensitive systems. We propose the development of a precise positioning system that can be implemented in terrestrial metropolitan networks that is also capable of interference avoidance, hi-jack prevention, and operational in GPS denied environments. The significant contribution of this work is the development of cognitive GPS system that utilizes a novel anti-jamming algorithm to dynamically allocate signal power so as to avoid interference. We also propose a resource elements encryption algorithm to prevent hi-jacking and GPS spoofing.

The information flow among the Constituent Systems of a System-of-Systems can take place via two different channels: the message transport along communication channels in cyber space which includes the human-to-human communication in natural language among the humans that are part of the Constituent Systems, and the indirect information flow via sensors and actuators to the physical environment, called the stigmergic information flow. In many cases the stigmergic information flow forms an important link for the closure of control loops that can lead to emergent behavior. This paper elaborates the concepts of stigmergy and compares the characteristics of the stigmergic information flow versus the message based information flow in a System-of-Systems.

The objective of this paper is to investigate the plausibility of applying Epoch-Era Analysis (EEA) as a systems engineering technique to evaluate whether an offshore subsea construction vessel (OSCV) can deliver sustained value to stakeholders over time in a complex, uncertain and changing technological, operational and commercial context. Additionally, the article discusses how to evaluate and interpret the results of such an analysis. As a basis for the EEA, a concise analysis of the current OSCV market and inherent development trends as to technology application and operational best practices should be included, to ensure realistic input parameters to the analysis.

This paper presents the characterisation of a concept System of Systems called the SmartPowerchair, in which existing pervasive technologies are integrated into a standard powered wheelchair to enhance the quality of life through independent living. Traditional Systems Engineering focuses on building the right system whereas System of Systems focuses on selecting the right combination of systems and their interactions to satisfy a set of frequently changing requirements. The SmartPowerchair can be characterised as a System of Systems due to the integration of a finite number of constituent systems which are independent and interoperable, and networked together for a period of time to achieve a certain higher goal. A high-level two-dimensional System of Systems model is developed to illustrate the lifecycle stages of System of Systems and different levels including the Component, System, System of Systems and Capability levels. Usability evaluations and workload measurements of a constituent system is also provided.

`System of systems (SoS)' is a special kind of system that appears more and more in many application domains. It has spawned active research across many technical domains and perspectives. One aspect of this research that has perhaps received less attention is the role of decision-making models to capture the essential collaborative nature of SoS. In this paper, we summarize a subset of the approaches presented on this topic in an effort to subsequently identify critical areas that remain in need of further work to improve the effectiveness of the models. We identify and briefly describe key areas and discuss concept applications in these areas. A link between models used in the design/planning stages and operations/control stage is found to be an especially useful endeavor and we recommend it to the research community.

This paper investigates the science of sensory and sensorimotor systems that enable navigation and natural flight in insects with application to the collaborative control of robots. The authors discuss fundamental research being conducted at the Autonomous Vehicle Systems Lab located at the University of the Incarnate Word on developing biologically inspired robots that emulate insect foraging and search behavior. Particle Swarm Optimization (PSO) technique is used in order to analyze the social characteristics of the studied insects and to implement those in the design of multi-robot systems. The authors will also present novel approaches for integrating the studied collective behavioral techniques for the collaborative and formation control of autonomous vehicles.

Large complex Industrial projects most often are interdisciplinary and require a complex systems engineering approach to guarantee success. In this paper we present a successful implementation of a true systems engineering approach to a summer internship program in industry. We exported the methods and lessons learned to an academic environment. For each project a group of six to fifteen students were selected to solve a practical industry problem and produce a detailed design for a specified project. Different aspects of the project plan were assigned to members of each group who were the most qualified or who expressed interest in a specific area of specialization. Three industrial and one academic implementation of this method are explained in this paper.

Multi-tenant clouds with resource virtualization offer elasticity of resources and elimination of initial cluster setup cost and time for applications. However, poor network performance, performance variation and noisy neighbors are some of the challenges for execution of high performance applications on public clouds. Utilizing these virtualized resources for scientific applications, which have complex communication patterns, require low latency communication mechanisms and rich set of communication constructs. To minimize the virtualization overhead, a novel approach for low latency network for HPC Clouds is proposed and implemented over a multi-technology software defined network. The efficiency of the proposed low-latency Software Defined Networking is analyzed and evaluated for high performance applications. The results of the experiments show that the latest Mellanox FDR InfiniBand interconnect and Mellanox OpenStack plugin gives the best performance for implementing VM-based high performance clouds with large message sizes.

A key element differentiating traditional systems from systems of systems is governance. While systems are characterized by belonging to a single governing authority, systems within a system of systems are often independently governed or governed by fully empowered entities. Such independence is a necessary condition for the autonomy of each constituent system and for enabling the concept of belonging. At the same time, the capability to be autonomous and the voluntary nature of belonging, enables a constituent system to voluntarily abandon the system of systems it belongs to as well. Yet, research has not addressed so far the implications and modeling of intended abandonment into the operational effectiveness of a system of systems. This paper presents the concept of system abandonment as a philosophical necessity in the definition of systems of systems, it discusses some visions to measure the risk of abandonment, and proposes a way forward to explore mitigation techniques.
