Demonstrating through-life and NEC requirements for defence systems

There are two major transformations currently occurring that significantly impact acquisition and management of military systems. Network Enabled Capability (NEC) demands careful consideration of interoperability for delivered systems; new systems must be introduced such that they are interoperable with current systems and legacy systems must be managed (upgraded, modified etc.) such that interoperability is maintained and, preferably, enhanced. Eventually, NEC considerations should become ‘business as usual’, but for the time being special consideration is needed. The second transformation is the introduction of the concept of Through Life Capability Management (TLCM). Although new systems have always been planned with consideration of their maintenance etc., TLCM has a wider scope. It requires consideration not only of the individual systems’ life cycles, but of the management of the super system in which new systems will operate. The whole life costs, risks, and development must be considered by systems designers and owners. These transformations are linked; interoperability is a key requirement of TLCM. Through a concept mapping of TLCM, Yue & Henshaw (1) have shown that TLCM implies a need for new approaches (new thinking) in defence systems design and acquisition. Also TLCM requires the defence supply chain (industry) to have a changed engagement in the delivery and management of systems. This, in turn, requires changes to the industry-customer relationship, such that new approaches to collaboration are a vital ingredient necessary for adherence to TLCM principles. The NECTISE (Network Enabled Capability Through Innovative Systems Engineering: www.nectise.com) programme was a large academic-industry research programme (part sponsored by industry) to investigate the implications for systems engineering arising from NEC and TLCM considerations. The programme included ten UK universities, and industry technologists and systems engineers from land, sea, air, and C4I domains. NECTISE considered systems processes and approaches from all parts of the capability management process (planning, design, change, and realisation in military operations). A number of new tools and processes were developed and an important part of the programme was to demonstrate these in context and together. This demonstration was achieved through development of a scenario that considered the full systems acquisition and management process. By linking a set of vignettes with different timeframes it was possible to track an exemplar system through the planning to realisation and use stages. The scenario development drew heavily on the TTCP GUIDEx approach to defence experimentation; this enabled effective multi-disciplinary collaboration and integration of many different research threads. This paper will describe the scenario planning activity and outcome and illustrate the manner in which linked research outputs were integrated into a systems engineering demonstration. The importance of systems architecting, both to the demonstration and (more importantly) as a key underpinning skill for TLCM and NEC will be emphasised. The approach taken in this demonstration of research has implications for the approaches that should be taken for defence procurement decision making in a TLCM and NEC characterised acquisition environment. These are described and the implications of TLCM for decision making is also highlighted

Synergy between biology and systems resilience

Resilient systems have the ability to endure and successfully recover from disturbances by identifying problems and mobilizing the available resources to cope with the disturbance. Resiliency lets a system recover from disruptions, variations, and a degradation of expected working conditions. Biological systems are resilient. Immune systems are highly adaptive and scalable, with the ability to cope with multiple data sources, fuse information together, makes decisions, have multiple interacting agents, operate in a distributed manner over a multiple scales, and have a memory structure to facilitate learning. Ecosystems are resilient since they have the capacity to absorb disturbance and are able to tolerate the disturbances. Ants build colonies that are dispersed, modular, fine grained, and standardized in design, yet they manage to forage intelligently for food and also organize collective defenses by the property of resilience. Are there any rules that we can identify to explain the resilience in these systems? The answer is yes. In insect colonies, rules determine the division of labor and how individual insects act towards each other and respond to different environmental possibilities. It is possible to group these rules based on attributes. These attributes are distributability, redundancy, adaptability, flexibility, interoperability, and diversity. It is also possible to incorporate these rules into engineering systems in their design to make them resilient. It is also possible to develop a qualitative model to generate resilience heuristics for engineering system based on a given attribute. The rules seen in nature and those of an engineering system are integrated to incorporate the desired characteristics for system resilience. The qualitative model for systems resilience will be able to generate system resilience heuristics. This model is simple and it can be applied to any system by using attribute based heuristics that are domain dependent. It also provides basic foundation for building computational models for designing resilient system architectures. This model was tested on recent catastrophes like the Mumbai terror attack and hurricane Katrina. With the disturbances surrounding the current world this resilience model based on heuristics will help a system to deal with crisis and still function in the best way possible by depending mainly on internal variables within the system --Abstract, page iii

Federated Embedded Systems – a review of the literature in related fields

This report is concerned with the vision of smart interconnected objects, a vision that has attracted much attention lately. In this paper, embedded, interconnected, open, and heterogeneous control systems are in focus, formally referred to as Federated Embedded Systems. To place FES into a context, a review of some related research directions is presented. This review includes such concepts as systems of systems, cyber-physical systems, ubiquitous computing, internet of things, and multi-agent systems. Interestingly, the reviewed fields seem to overlap with each other in an increasing number of ways

Tradespace and Affordability – Phase 1

One of the key elements of the SERC’s research strategy is transforming the practice of systems engineering – “SE Transformation.” The Grand Challenge goal for SE Transformation is to transform the DoD community’s current systems engineering and management methods, processes, and tools (MPTs) and practices away from sequential, single stovepipe system, hardware-first, outside-in, document-driven, point-solution, acquisition-oriented approaches; and toward concurrent, portfolio and enterprise-oriented, hardware-software-human engineered, balanced outside-in and inside-out, model-driven, set-based, full life cycle approaches.This material is based upon work supported, in whole or in part, by the U.S. Department of Defense through the Office of the Assistant Secretary of Defense for Research and Engineering (ASD(R&E)) under Contract H98230-08- D-0171 (Task Order 0031, RT 046).This material is based upon work supported, in whole or in part, by the U.S. Department of Defense through the Office of the Assistant Secretary of Defense for Research and Engineering (ASD(R&E)) under Contract H98230-08- D-0171 (Task Order 0031, RT 046)

A conceptual system design and managerial complexity competency model

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Complex adaptive systems are usually difficult to design and control. There are several particular methods for coping with complexity, but there is no general approach to build complex adaptive systems. The challenges of designing complex adaptive systems in a highly dynamic world drive the need for anticipatory capacity within engineering organizations, with a goal of enabling the design of systems that can cope with an unpredictable environment. This thesis explores this question of enhancing anticipatory capacity through the study of a complex adaptive system design methodology and complexity management competencies. A general introduction to challenges and issues in complex adaptive systems design is given, since a good understanding of the industrial context is considered necessary in order to avoid oversimplification of the problem, neglecting certain important factors and being unaware of important influences and relationships. In addition, a general introduction to complex thinking is given, since designing complex adaptive systems requires a non-classical thought, while practical notions of complexity theory and design are put forward. Building on these, the research proposes a Complex Systems Life-Cycle Understanding and Design (CXLUD) methodology to aid system architects and engineers in the design and control of complex adaptive systems. Starting from a creative anticipation construct - a loosening mechanism to allow for more options to be considered, the methodology proposes a conceptual framework and a series of stages to follow to find proper mechanisms that will promote elements to desired solutions by actively interacting among themselves. To illustrate the methodology, a financial systemic risks infrastructure systems architecture development case study is presented. The final part of this thesis develops a conceptual model to analyse managerial complexity competency model from a qualitative phenomenological study perspective. The model developed in this research is called Understanding-Perception-Action (UPA) managerial complexity competency model. The results of this competency model can be used to help ease project manager’s transition into complex adaptive projects, as well as serve as a foundation to launch qualitative and quantitative research into this area of project complexity management

Leveraging enterprise architecture to enable integrated test and evaluation sustainability

Thesis (S.M. in Engineering and Management)--Massachusetts Institute of Technology, Engineering Systems Division, 2011.Cataloged from PDF version of thesis.Includes bibliographical references (p. 62-64).An analysis was performed to investigate how enterprise architecting methods can be applied to an integrate test and evaluation enterprise and make it a more sustainable enterprise to provide continuous value in the face of an evolving DoD landscape. Enterprise sustainability is the ability of an enterprise to maintain economic viability through optimal resource management and preservation over an extended duration. Through the application of the eight lenses of enterprise architecting, it was found that a more holistic understanding of a Major Range and Test Facility Base (MRTFB) enterprise's current state could be achieved. This approach also supported identifying gaps that exist between the ability of the current-state MRTFB to deliver value and the value delivery that is required by its key stakeholders. The importance of expanding the information view of enterprise architecting to encompass the entire enterprise infrastructure was also studied. Through the expansion of the information view to an infrastructure view, a more complete depiction of the MRTFB enterprise was achieved. The specific importance of the energy infrastructure to a sustainable enterprise was also explored. Through the application of enterprise architecting, the interrelations between the energy infrastructure and the other views, such as processes, services, and knowledge, and the other supporting infrastructure components, such as facilities, land, physical assets, communication networks, and IT networks, can be established. It was found that the energy infrastructure is a core enabler for our technology-based society, and coupled with the current societal focus on green and sustainable energy provides a focal point for enterprises to leverage and initiate transformation efforts to align the energy infrastructure with larger enterprise strategic objectives.by Arlan C.
