Abstract [en]

In a system-of-systems, independent constituent systems collaborate to achieve broader capabilities they cannot provide on their own. This paper investigates the nature of the constituent system capabilities beyond basic operational actions, to achieve a deeper understanding of what is required to participate in a system-of-systems. Through a case study of industrial ecosystems, the need is shown for planning how to use basic operational capabilities, for dynamic capabilities to achieve long-term evolution, and for resilience capabilities to deal with perturbations. This also affects the governance of the system. The findings are used to extend an existing conceptual model of constituent systems and to characterize collaboration in a system-of-systems that implements a value network.

Abstract [en]

Cybersecurity is an important concern in systems-of-systems (SoS), where the effects of cyber incidents, whether deliberate attacks or unintentional mistakes, can propagate from an individual constituent system (CS) throughout the entire SoS. Unfortunately, the security of an SoS cannot be guaranteed by separately addressing the security of each CS. Security must also be addressed at the SoS level. This paper reviews some of the most prominent cybersecurity risks within the SoS research field and combines this with the cyber and information security economics perspective. This sets the scene for a structured assessment of how various cyber risks can be addressed in different SoS architectures. More precisely, the paper discusses the effectiveness and appropriateness of five cybersecurity policy options in each of the four assessed SoS archetypes and concludes that cybersecurity risks should be addressed using both traditional design-focused and more novel policy-oriented tools.

Abstract [en]

Understanding the needs and constraints of systems in general and a system-of-systems in particular can be challenging, yet crucial. Relying only on upfront activities will not be sufficient. Important information can be gathered around the performance and behavior of the system as well as stakeholder needs in operation. A digital twin is a way to model and understand the operation of a system. To understand the challenges and enablers related to digital twins in a system-of-systems context, we performed a literature study. In total, only 10 papers were identified that explicitly address this topic, all from the last five years, indicating that this is an active field of research. The papers revealed that definitions and terminology are unclear and that similar challenges as for systems-of-systems also exist for systems-of-digital twins. The complexity and dynamic nature of systems-of-systems motivate further study of digital twins to understand needs and constraints. However, key challenges such as concepts and principles of digital twins for systems-of-systems, cost and benefits, and evolution needs to be better understood.

Abstract [en]

This study presents a core ontology for missions and capabilities in systems of systems. The aim of the study is to create artifacts that facilitate precise understanding of fundamental concepts of SoS. An ontological approach proposes and develops taxonomic homogeneity and structural knowledge of SoS. The ontology development process involved workshop sessions with industry experts and meta modelling of the different concepts and their relationships. The ontology includes thirteen concepts of types physical things, people, information and mixed. These concepts are defined and their relations are briefly described. The developed ontology is further illustrated using a wildfire scenario case study.

Abstract [en]

Crisis management (CM) is facing new challenges due to the increasing complexity of contemporary society. To mitigate a crisis, it is often necessary for a collection of independent systems, people, and organizations to cooperate. These collaborating entities constitute an interconnected socio-technical system of systems (SoS). An important question is how a CM SoS should be constructed to minimize the risk of failure and accurately handle a crisis. SoS pose new challenges in analysing risk during interactions. This paper investigates whether the risk analysis method STAMP (System-Theoretic Accident Model and Processes) is suitable for SoS, using a forest fire rescue operation case study. Results show characteristics of various risk sources and identify some SoS characteristics, such as dynamic structure and latent risks, that are not sufficiently handled in STAMP. The study further contributes to the body of knowledge by presenting potential directions for research on SoS risk assessment methods.

Abstract [en]

Systems of systems consist of independently owned, operated, and developed constituent systems that work together for mutual benefit. Co-opetitive systems of systems consist of constituent systems that in addition also compete. In this paper, we focus on quality requirement engineering for a constituent systems developer in such SoS. We discuss the needs and requirements of a structured quality requirements engineering process, with examples taken from the transportation domain, and find that there is a need for mediators and agreements between constituent systems developers to enable quality data exchange.

Abstract [en]

Systems of systems engineering is aimed at developing solutions that provide the capability to fulfil a need that cannot be met by an integrated system. In many SoS, there is a need to solve several tasks at the same time. Each set of constituent systems that collaborate to solve such a task is a constellation. In this paper, we discuss the process of forming such constellations. We focus on collaborative systems of systems and describe conceptual models for the formation of constellations.

Abstract [en]

Systems-of-systems are designed to provide a capability that their constituent systems cannot achieve individually. A key property is that the constituent systems have some degree of operational and managerial independence. The concepts of capability and independence are thus central to the field of systems-of-systems. Yet the contemporary literature and standards only give vague definitions of these terms. This vagueness is a barrier to progress in the field, and this paper aims at contributing with a more detailed conceptualization. It describes a system capability as a state-transforming process that uses certain resources. Independence means that the system has a choice about when and how its capabilities should be activated. This requires that the system is an intelligent agent with a notion of utility, a perception of the world around it, and a decision-making capability. When given a mission, the system can complete that mission by activating appropriate combinations of capabilities. A system-of-systems can decompose its mission into parts that correspond to the capabilities of various constituent systems.

Abstract [en]

Design patterns are an established approach for reusing knowledge about good solutions to recurring problems. Patterns can be seen as a way of describing the best practices, and have been used in many different fields, ranging from building architecture and city planning to software development. There are also scattered results relating to patterns for systems-of-systems. The purpose of this paper is to summarize and review the literature on patterns for systems-of-systems and make a synthesis of a recommended approach for the field. Specifically, the novel contributions of the paper are to propose a consolidated structure for describing individual patterns and suggest the dimensions along which a pattern catalog can be organized. The paper also summarizes the concrete patterns suggested in the existing literature and classifies them according to the recommended structure.

Abstract [en]

Systems of systems (SoS) leverage dynamic configuration of independent systems to achieve a capability neither of the independent constituent systems can achieve on their own. Therefore, SoS engineering goes beyond addressing requirements to addressing capabilities. Due to the independence of the constituent systems, capability is formed by complex interdependence of legacy systems. It is also subject to uncertainty of the evolutionary development of the SoS, making it important to not only see the bigger picture but to plan for the changing capability patterns in the life of an SoS. This study looks at the body of knowledge surrounding definitions, support systems and practices around the concept of capability in the context of SoS. The results show; context dependent nature of the definition of capability, country-specific support systems, ongoing efforts to form more robust frameworks and dominant establishment of this theme in the defense sector.
