We live, work and play within interacting and embedded systems of systems. While systems of systems engineering may be perceived as primarily physical or “hard” infrastructure, we live in critical systems of systems that emerge within physical and social systems. One such example is the living community system, one that strongly impacts our health and the way we live. The complex interconnected living environment is becoming a central focus for improvement given its strong influence on health in general and on how chronic conditions arise and persist. Such a strong focus on our community living environment has prompted various level regions (i.e. cities, districts) to take action in their communities. Stakeholders have turned to national data sources to inform a region of the many factors that describe it. However, these multiple factor datasets should be analyzed holistically as a system rather than individually. Consequently, this work develops a system of systems community typology from national data describing types of factor value combinations within a region. This paper presents a method of integrating multifactorial community data using a clustering based method to determine holistic system of systems community typologies.

How to measure and train for adaptability has emerged as a priority in military contexts in response to emergent threats and technologies associated with asymmetric warfare. While much research effort has attempted to characterize adaptability in terms of accuracy and response time using traditional executive function cognitive tests, it remains unclear and undefined how adaptability should be measured and thus how simulation-based training should be designed to instigate and modulate adaptable behavior and skills. Adaptable reasoning is well-exemplified in the rescue effort of Apollo 13 by NASA engineers who repurposed available materials available in the spacecraft to retrieve the astronauts safely back to earth. Military leaders have anecdotally referred to adaptability as “improvised thinking” that repurposes “blocks of knowledge” to device alternative solutions in response to changes in conditions affecting original tasks while maintaining end-state commander’s intent. We review a previous feasibility study that explored the specification of Reusable Modeling Primitives for models and simulation systems building on Dimensional Analysis and Design Structure Matrix for Complexity Management formal methods. This Dimensional Analysis Conceptual Modeling (DACM) paradigm is rooted in science and engineering critical thinking and is consistent with the stated anecdotal premises as it facilitates the objective dimensional decomposition of a problem space to guide the corresponding dimensional composition of possible solutions. Arguably, adaptability also concerns the capability to overcome contradictions, detections, and reductions, which we present in an exemplar addressing the contradiction of increased drag due to increased velocity inherent to torpedoes. We propose that the DACM paradigm may be repurposed as a critical thinking framework for teaching the identification of relevant components in a theater of military operations and how the properties of those components may be repurposed to fashion alternative solutions to tasks involving navigation, call-for-fires, line-of-sight cover, weather and atmospheric effect responses, and others.

This paper describes a System of Information Systems (SoIS) to capitalize heterogeneous resources of collaborative activities in perspective of strategic analysis. The de-centralization of work processes have led organizations to respond to their dynamic environments and nomads practices by using collaborative software such as brainstorming environment. The outputs of a brainstorming are huge amounts of knowledge that need to be shared, capitalized and structured to generate a support for new discussions. While preparing, or during a brainstorming, participants may use other systems/web tools to gather more information. This information are external resources that improve the brainstorming efficiency and have to be capitalized in the same way as the knowledge produced during the brainstorming to “re-invent” the way of strategic analysis. It is therefore a matter of managing a set of resources generated by a set of independent systems. For this, we propose a solution based on SoIS approach. More precisely, we propose a solution to integrate a collaborative application called ECOPACK within a large SoIS called MEMORAeSoIS. ECOPACK is a digital ecosystem that meets the needs of ideation, innovation and strategic analysis. It offers several functionalities such as the capitalization of resources produced during a meeting. However, as mentioned above, participants may use resources coming from other systems. To allow capitalizing external resources, we use the MEMORAeSoIS that provides the ability to manage resources of autonomous systems. We illustrate our proposition by a scenario on the challenges of France’s naval defense. This paper provides a solution based on the System of Information Systems approach to capitalize collaborative activities.

Naval ships building requires numerous domains of expertise raising a major challenge to design, produce, support and retire a system that is composed of thousands of equipment’s and features, and which will be operated by different navies for several missions around the globe. Coming with the digitalization of the ships, the success of MBSE (Model-Based System Engineering) approach in software-intensive systems has led major industrial actors, of which Naval Group, to adopt MBSE for large scale projects. Nowadays industry has to go further, as more and more systems have interactions between each other in a systems-of-systems prospective, as well as MBSE is becoming more mature. One major challenge is to run an efficient system engineering process, because it will secure the following other phases of the product lifecycle. The system engineering system required for an Aircraft-carrier, frigates and submarines design and development involves numerous companies and teams, in several domains of expertise. The number and the complexity of the involved enabling systems are also important: requirement and quality management tools, modelling and simulation tools, 3D design tools, etc… The communications between those teams, as well as the interfaces between those tools, are key points for a good design phase. So this paper proposes to take an MBSE approach to enhance these communications during the engineering phases, and to enable this integration between the different enabling systems that supports the engineering process. Another advantage is to establish the numerical continuum between the several engineering levels, domains and data, and to enhance automation of this integration by using the power of the model-based standards and associated frameworks. The innovation comes from the idea of engineering a new enabling system, able to define the system engineering integrated toolchain, tailored for each complex socio-technical system engineering process, and that this engineering is not performed by tool vendor, but by the target program team. So to define this system, we have tried to apply the fundamental principles of system engineering, onto the engineering system it-self, within a model-based approach: (i) the specification first, by giving more details on the motivations, second by expressing a simple set of requirements, modelled in a set of functions; (ii) the enterprise architecture modelling through a set of artefacts representing the System Engineering meta-model, and a first level of allocation; (iii) At last, as an early validation phase, where the relevancy and benefits of this approach will be discussed.

Although the concept of System of Systems (SoS) has become quite popular, most applications are still hand crafted. In this paper we present a framework, called MBA for Memory-Broker-Agent, addressing the development of systems of systems from an engineering perspective. The main features of the framework result from the experience gained from building an SoS for developing software collaboratively. In the paper we recall the requirements for building an SoS and show how they can be met by using a multi-agent substrate. The MBA framework is a first step towards proposing a generic platform for developing systems of systems.
尽管“系统的系统”(System of Systems, so)的概念已经变得相当流行，但大多数应用程序仍然是手工制作的。在本文中，我们提出了一个框架，称为内存-代理-代理的MBA，从工程的角度解决了系统的系统的开发。该框架的主要特性来自于为协作开发软件而构建SoS的经验。在本文中，我们回顾了构建SoS的要求，并展示了如何通过使用多智能体基板来满足这些要求。MBA框架是为开发“系统的系统”提出通用平台的第一步。

Product service systems (PSS) can be understood as an innovation / business strategy that includes a set of products and services that are realized by an actor network. More recently, PSS that comprise System of Systems (SoS) have been of increasing interest, notably in the transportation (autonomous vehicle infrastructures, multi-modal transportation) and energy sector (smart grids). Architecting such PSS-SoS goes beyond classic SoS engineering, as they are often driven by new technology, without an a priori client and actor network, and thus, a much larger number of potential architectures. However, it seems that neither the existing PSS nor SoS literature provides solutions to how to architect such PSS. This paper presents a methodology for architecting PSS-SoS that are driven by technological innovation. The objective is to design PSS-SoS architectures together with their value proposition and business model from an initial technology impact assessment. For this purpose, we adapt approaches from the strategic management, business modeling, PSS and SoS architecting literature. We illustrate the methodology by applying it to the case of an automobile PSS.

A major research challenge for the design of a software-intensive System-of-Systems (SoS) is the formal description of its software architecture. The main complicating factor is that an SoS, by definition, has its architecture designed to produce emergent behavior for fulling missions. But, by definition, an emergent behavior is an “unexpected” behavior. By “unexpected”, we mean a behavior of a whole (i.e. the SoS) that cannot be predicted through analysis only of its parts (i.e. the constituent systems of the SoS), or stated simply: the behavior of the SoS is other than the sum of the behaviors of its constituent systems. The oxymoron is thereby: how to formally design and describe the software architecture of an SoS to exhibit “expected” (by design) “unexpected” (emergent) behaviors that stem from the interactions among the constituent systems of the SoS? To address this oxymoron, this paper investigates the notion of emergent behavior for clarifying the boundaries of this notion for SoS and then presents the architectural emergentist framework that we developed to enable the architectural description of emergent behavior of software-intensive SoSs.

System of Systems (SoS) engineering is a challenging research direction because an SoS has distinctive characteristics in comparison to distributed systems. UPMD and SysML provide adequate frameworks and notations which help in the process of modeling and architecting SoS. Projects such as DANSE and COMPASS have selected the most relevant views among the numerous views of UPDM. By nature, an SoS evolves after its initial deployment. To deal with evolutions, the architect needs to model configurations, what was not considered in previous state of the art. Modeling configuration is indeed key before we can model the evolution itself. In this paper, our contribution is a new modeling process, based on UPDM and SysML, that helps the architect in designing the configuration of an SoS. The proposed process is illustrated with the case study of the French emergency service.

This paper presents findings from applying social network analysis tools and techniques to a network of Department of Defense (DoD) systems. The network of systems includes 349 systems that serve as the nodes in the networks and the edges represent shared operational activities. This method captures the versatility of these systems as it identifies systems that can perform the same function for the DoD. Additionally, the visualization of the network enables the identification of potential systems of systems that emerge from the larger network of systems. These systems of systems cluster together around the edge of the overall network and include a logistics, electronic warfare, and force protection system of system. Like most system of systems, these potential groups of system of systems are composed of independent systems, demonstrate emergent behavior, are managed by different services, and interoperate to provide value to the DoD stakeholders. Additionally, these system of systems demonstrate the characteristics of systems of systems from the literature. It appears that applying social network analysis visualization techniques could assist systems engineers in the identification of systems of systems.

It appears that applying social network analysis visualization techniques could assist systems engineers in the identification of systems of systems.","PeriodicalId":314200,"journal":{"name":"2018 13th Annual Conference on System of Systems Engineering (SoSE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116091336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we discuss the role played by System of Information Systems (SoIS) as support for organizational memory. The use of an information system for managing organizational memory improves the precision, the recall, the completeness and the feedback. With the use of Information and Communication Technologies (ICT), the centralized organization is turned into a networked organization. This implies a very different report of data, documents and knowledge and a new vision of the role of information technology in the organization. All these different technologies as to be taken into account into the information system. Thus the system moves towards a System of Information Systems. In our work we made the choice to link these different systems in one hand by a leader system and the other hand to use an ontology to manage the interoperability of the constituent systems and the leader system. We defined a semantic model of SoIS and an architecture dedicated. Based on this work, we developed a prototype called MEMORAeSoIS. We will show in this paper how the retention facilities (acquisition, retention, retrieval, and artifacts of cooperation) in the stages in the organizational memory could be overcome by the means of System of Information Systems.
