In last year's conference, we presented a system of systems (SoS) approach for the development of a generalized mathematical model for modeling complex systems with integrated WSNs so that necessary benchmark cases can be derived. Additionally, this will allow for a standardized evaluation of performance measures for the different mobility models of WSNs. The generalized model has been tested mathematically...
The UK's Armed Forces can be deployed to almost any part of the world and are often operating in some of the world's most inhospitable conditions where they can also be under threat from hostile actions. When deployed to these areas the troops cannot rely upon host nation support and therefore have to come with everything they may need in order to carry out operations from that location. A secure...
Emergent behavior is a core trait of SoSs. But the emergence cannot be predicted before its appearance. We propose a method which using Semi-autonomous Agent based simulation to detect the emergent behaviors of SoSs. Agent based Modeling and Simulation are available for the observation of emergent behaviors of SoSs. We propose the multi-agent based simulation methods to demonstrate the evolution of...
This paper presents an integration effort combining a number of soft factors modelling tools and considers the potential impact of such an overall tool in a system of systems environment. The paper introduces the tools developed and how it is envisaged they will work together to provide a comprehensive, coherent output. It is suggested that a suite of interoperable tools of this form could aid the...
The level of complexity in Systems of Systems is increasing as more complex functionality emerges from the interaction of individual components. As networks become more complex it becomes more difficult for an individual to identify potential safety risks. We know, from previous accidents, that poor understanding of networks can be dangerous. In this paper, we demonstrate the potential value of incorporating...
There is growing recognition within industry that for system growth to be sustainable, the way in which existing assets are used must be improved. Future systems are being developed with a desire for dynamic behaviour and a requirement for dependability at mission critical and safety critical levels. These levels of criticality require predictable performance and as such have traditionally not been...
This paper identifies four challenges facing researchers and practitioners of Systems Engineering and Systems Thinking in defence capability: Language, Complexity, Longevity and Agility. Its purpose is to stimulate a debate on how best to meet these through systems research and systems engineering. It argues that this will require innovation in the development of new systems engineering practices...
This paper presents the first of two case studies conducted in 2009, to evaluate a concept for specifying and designing a Health Management System (HMS). This first case study made use of a representative Unmanned Aerial Vehicle fuel system. Conflicting information requirements relating to the health of the fuel system were defined for a given stakeholder (Fuel System Maintenance Engineer). Following...
Scenarios are frequently used within techniques for planning and designing systems. They are an especially helpful means of visualizing and understanding the incorporation of new systems within systems of systems. If used as the basis for decisions about candidate designs, then it is important that such decisions can be rationalized and quantitative assessment is particularly important. In this paper,...
The evolutionary nature of Unmanned and Autonomous systems of systems (UASoS) acquisition needs to be matched by evolutionary test capabilities yet to be developed. As part of this effort we attempt to understand the cost and risk considerations for UASoS Test and Evaluation (T&E) and propose the development of a parametric cost model to conduct trade-off analyses. This paper focuses on understanding...
The principles and methods of Model Driven Architecture are applied to the problem of requirements traceability for a System of Systems (SoS). Model transformations of operational threads are used to reduce the complexity of modeling mission requirements and their flow into the architecture of the SoS. The allocation of requirements to operational mission threads (OMTs) rather than to individual systems...
Complex systems are specified, designed, built and tested by humans, all of whom are immersed in a cultural environment that colours their emotions, cognition, decisions and behaviours. This paper presents a brief overview of culture, its sources, its measurement and its effects on the performance of complex systems. This paper also describes a series of culture and personality modelling tools that...
Face feature tracking in real-time conditions is one of the most challenging problems in the field of computer vision. A completely new approach using ”System of Systems” Model has been developed for feature tracking. A system of robust and intelligent tracking systems has been presented. A multi stage Hierarchical Quality Monitoring and Recovery Network has been developed, which makes the tracking...
The paper discusses a system of systems multi-paradigm approach to the modeling of Demand Responsive Transport systems. It contains a brief overview of issues which appear during modeling of such systems, considers various multi-agent architectures and describes some algorithms which can be used for modeling. Also the paper provides some details about previous investigations on this topic, in particular:...
During the past few years, research in the field of cooperative control of swarm of robots and specially UAV has continuously increased. In order to develop research in the field of swarm of UAV this paper identifies three problems: the development of a testbed for UAV, the implementation of an ad hoc network and a protocol based on network control, and a consensus control algorithm for cooperative...
This paper focuses attention on how managers can put in place a framework for reducing organizational vulnerability through counteracting cyber threats. Attention is focused on how senior managers can devise a resilience strategy that incorporates counter intelligence and places risk in a manageable context. Reference is made to placing cyber security in context, and a Cyber Security SLEPT analysis...
Testers need the ability to adapt test planning on the order of days and weeks. PATFrame will use its reasoning engine to prescribe the most effective strategies for the situation at hand. Strategies in this context include methods of experimental designs, test schedules and resource allocation. By facilitating rapid planning and replanning, the PATFrame reasoning engine will enable users to use information...
The potential market of robots that can helpfully work at home is increasing, and such robots are required to possess force and tactile sensors achieving dynamic and cooperative interactions with their users. We proposed virtual force sensing (VFS) which, is a versatile solution allowing high spatial resolution and degrees of freedom instead of embedding force sensors in robots/machines. The technological...
