    The Development of complex products in a satisfactory way is a difficult task. This is confirmed by the increasing number of recalls and customer complaints. In order to achieve a high product quality, different approaches were developed; one is the Generic System Engineering (GSE), a method that fits the complex product system in a standardized system model. The product system is in fact influenced to a high degree by the environment. To consider this impact, this paper discusses the structuring of the environment into processes and locations and their influences to the product system. This allows the systematic use of field data to limit the quantity of elements and their interaction in the processes and locations in order to improve the process of problem-solving. The benefit is to learn from mistakes in the context of the GSE. This supports cause-analysis, effect-analysis and therefore the enhancement of product systems. View full abstract»

    Design of a web-based thesaurus for Systems of Systems Engineering (SoSE) discipline is presented in this article. Due to lack of linguistic clarity within this emerging discipline, there is a strong need to represent and interpret SoS concepts and terms to align heterogeneous models, and tools and techniques developed for SoS operations, management and its governance. A Blackboard-based systems approach is therefore used to devise a model, providing a mechanism for high level organisation and sharing of knowledge and information within the SoSE thesaurus system. To illustrate its applicability, a scenario derived from realistic use cases is provided. The potential benefits of this research are identified and a brief description of intended further work is given. View full abstract»

    In system of systems engineering, stakeholders are individuals, groups or organizations that stand to gain or lose from the success or failure of a system of systems. Systems of systems pose unique problems for stakeholder analysis due to their evolutionary nature, emergent behavior, operational independence, managerial independence, and geographical distribution of their constituent systems. This paper proposes the use of social networks and crowdsourcing to identify and prioritize the stakeholders for system of systems projects. The proposed method crowdsources the stakeholders to recommend other stakeholders, builds a social network of stakeholders, and prioritizes stakeholders using social network measures. The paper describes the method, and discusses the strengths and limitations of applying the method in system of systems projects. View full abstract»

    The major challenge that the big data era brings to the services computing landscape is debris of unstructured data. The high-dimensional data is in heterogeneous formats, schemaless, and requires multiple storage APIs is some cases. This situation has made it almost impractical to apply existing data mining techniques which are designed for schema-based data sources in a knowledge discovery in database (KDD) process. In this paper, a tool called TouchR is proposed which algorithmically relies on the Hidden Markov Model (HMM) to extract terms from data silos; specifically, distributed NoSQL databases- which we model as network graph. Our use case graph consists of storage nodes such as CouchDB, Neo4J, DynamoDB etc. The evaluation of TouchR shows high accuracy for terms extraction and organization. View full abstract»

    This study has been studied SIRMs (Single Input Rule Modules) connected fuzzy inference model in order to provide the insight into fuzzy control systems. The framework consists of two propositions: To guarantee the convergence of optimal solution, a set of fuzzy membership functions (admissible fuzzy controller) which are selected out of continuous function space is compact metrizable. And assuming approximate reasoning to be a functional on the set of membership functions, its continuity is proved. Then, we show the existence of SIRMs which minimize (maximize) the integral performance function of the nonlinear feedback fuzzy system. View full abstract»

  • A capability based approach to enterprise transformation

    The paper is about the drastic transformation of the strategy and business model of the Russian information technological enterprise which incorporates autonomous but interrelated business units: in 2001 top management of the IBS Company made the decision to switch to the information technology services and consulting area. The creation of new capabilities was the transformation objective. Capability based approach was successfully applied to achieve the transformation goals. An “ES/SoS nuclear model” has been introduced to describe the transformation. The model represents the enterprise as the “hard business nucleus” or kernel (major business-agents, who really make the business), a “soft business shell” (non-material environment: governing media, competences, knowledge, etc. - intangible assets), and the “cloud of extended enterprise” (clients, partners, etc., interlinked by common “across”-business processes). The great majority of transformation activities and outcomes lie in the ES/SoS's “soft shell” which includes new capabilities, governing relations, competences, etc. View full abstract»

    Detecting and tracking unconstrained hands in videos is a basic technique for sign language recognition. In current hand detection methods, AdaBoost classifier based on Haar-like features is known to be fast and robust against scale change and rotation. However, its performance drops sharply when the background is complicated or the hand and other skin-color parts overlap. Insufficient training data also decreases the performance. This paper proposes a new training method for Haar-like features based AdaBoost classifier with insufficient data, and a hand detector integrating Haar-like features, skin-color and motion cue together. Also we present a novel hand tracking technique. Experimental results have shown that the proposed method obtains a promising detecting rate of 99.9%, and more than 97.1% of the tracked hands are extracted in proper size. In summary the proposed method is more robust than AdaBoost classifier against complicated background, scale change and rotation. View full abstract»

    The emergence of Systems of Systems Engineering (SoSE) poses challenges to the consistent use of terminology within and/or across heterogeneous sectors such as transport, energy and defence. In preparation for Horizon 2020, an €80 billion financial instrument running from 2014 to 2020 to implement the Europe 2020 strategy, the European Commission funded T-AREA-SoS project to formulate a strategic research agenda for SoSE that spans US and Europe activities. As part of T-AREA-SoS, a thesaurus will be created to ensure that SoS concepts and terms are consistently interpreted, and to provide an artefact that will be of significant assistance to planners of future programmes in SoSE. This paper proposes an approach for the formalisation and mapping of terminologies for a SoSE thesaurus development. This paper also discusses the theoretical foundations and exemplars of this applied approach in addition to the user interface specification for a proposed web-based thesaurus development.

  • Configuration of a standoff detection system via rapid, model-based systems engineering

    Page(s): 52 - 57

    This paper presents a model-based systems engineering approach developed for rapid analysis of complex systems, not requiring the use of high computational resources. The basis of the approach involves the mapping of three basic systems engineering metrics, namely, Measures of Performance (MOP) to Measures of Effectiveness (MOE) to a single Figure of Merit (FOM), through metamodeling. Through this approach, analysts can leverage validated metamodels to map system measures, from component level MOPs to the overall system FOM in real-time to support decisions under constrained time-frames. Through metamodeling we achieve approximations of the simulation model in mathematical form, which alleviates long run times and the need for large computational resources. The metamodels also provide an effective means to aggregate a simulation's multiple outputs of interest via a preference function. These two approaches together form the foundation of this rapid, model-based systems engineering approach. The effectiveness of this model-based approach is demonstrated on configuring a standoff detection system. View full abstract»

    This paper will discuss the system level verification and validation test program for the surface capability of the Mars Science Laboratory (MSL) Curiosity Rover. MSL has many similarities to its predecessors, the Mars Exploration Rovers Spirit and Opportunity. However, Curiosity's diverse science payload, new sampling system, and overall scale led to new challenges in development and testing. The rover hardware and software were developed to allow certain functions to work in parallel to maximize the science that could be done each day on Mars. This led to complex behavioral interactions, which had to be tested and verified before they could be trusted. An incremental test program was developed that first exercised and verified individual functions and then validated system capabilities in mission-like scenarios. The plans, execution and results of these mission-like surface system tests will be presented. View full abstract»

    This paper will discuss systems engineering challenges in development of the Mars Science Laboratory Curiosity Rover. As of the writing of this paper, Curiosity has been successfully exploring the surface of Mars for months, but during development it was not always clear it would be a success. MSL is by design three spacecraft in one: The cruise system to get from Earth to Mars; the entry descent and landing system; and the Rover to perform the intended scientific exploration. Each of these has it own unique challenges and is intertwined given the integrated nature of the design. The rover's complex science payload, sampling system and overall scale resulted in many technical challenges. This paper will present a few examples of the systems engineering challenges overcome during the development of the Curiosity rover. View full abstract»

  • A meta-system architecture for the energy-water nexus

    Page(s): 76 - 81

    The energy-water nexus has been studied predominantly through discussions of policy options supported by data surveys and technology considerations. At a technological level, there have been attempts to optimize coupling points between the electricity and water systems to reduce the water-intensity of technologies in the former and the energy-intensity of technologies in the latter. To our knowledge, there has been little discussion of the energy-water nexus from an engineering systems perspective. As the energy-water nexus presents a large scale, multidisciplinary problem with various technological and non-technological dimensions, efforts for coordinated control, operation & planning of the energy and water systems would benefit from the modeling platforms developed in systems engineering. This paper presents a meta-architecture of the energy-water nexus in the electricity supply, engineered water supply and wastewater management systems developed using the Systems Modeling Language (SysML). This meta-architecture serves to elucidate the nexus for qualitative discussions. Once instantiated such an architecture can serve as a conceptual framework upon which quantitative planning and control approaches can be based. View full abstract»

    A robotic system of crane systems is proposed and simulated for a vanilla pollination application. The system could be used for other applications where a grid of posts is serviced in an area suitable for overhead cranes. Existing crane systems could work together with new crane equipment in a hierarchical manner. A docking crane system with two or more six degrees of freedom cranes services the area around posts upon which it docks. Vision is used for subject recognition and control feedback.

  • Modelling of a Nuclear Emergency Plan: A system of systems engineering approach

    Page(s): 87 - 92

    A nuclear emergency (NE) may dramatically impact on several interrelated domains such as health, critical infrastructures, land use, etc. A Nuclear Emergency Plan (NEP) involves multiple systems acting in a coordinated way, according to a pre-established organisation, which is endowed with a set of rules, communications and commands. Usually the NEP is top-down defined. In this paper we propose the definition of NEPs from a System of Systems Engineering (SoSE) approach. This conceptualisation facilitates the assessment and analysis of key indicators: the resilience, responsiveness and effectiveness of NEPs. We illustrate the advantages of this approach with the analysis of the communications network (CN) in a real case study. View full abstract»

  • Recognising further concepts from complex systems research in SoSE

    System of systems (SoS) and System of Systems Engineering (SOSE) are made up of independent autonomous system. SoS has used a number of concepts from complexity theory, such as inclusion of autonomous and independent systems and emergence. However, there are a number of other concepts that have not been so readily used in SoSE which have been clearly enunciated in complex systems research papers. These include self organization, complexity leadership, stability levels and notions of being on the edge of chaos, phase history and initial conditions, co-evolution, hierarchy versus networked, and redundant resources. These concepts are examined and some implications for use in SoSE proposed. Although it is considered desirable to include these in SoSE architecture, it is concluded that SoSE architecture is not adequately developed so inclusion in processes to be used in SoSE architecture is the best approach.
