  • The Systemic Effects of Fatigue on Military Operations

    Publication Year: 2007 , Page(s): 1 - 6
    Save to Project icon | Click to expandAbstract | PDF file iconPDF (4383 KB)  

    This paper uses recent accidents and incidents to identify the systemic causes of fatigue in military operations. At a strategic and tactical level, it is argued that inadequate risk assessments and a lack of 'joined up' planning often leave soldiers in situations where they are likely to make errors of commission and omission. At an operational level, fatigue has an insidious effect on the intera... View full abstract»

  • Human Factors Engineering of Interfaces - Connecting Control Centres

    Publication Year: 2007 , Page(s): 7 - 12
    Save to Project icon | Click to expandAbstract | PDF file iconPDF (3890 KB)  

    Railway projects rarely exist in isolation. In some cases, communications are required between control centres, in others, the centres themselves are amalgamated. Even for metro systems, interfaces may exist between station-based systems and line control. In most cases, particularly with heavy rail, a new or upgraded railway system will connect to existing lines, built for different needs and with... View full abstract»

    Save to Project icon | Click to expandAbstract | PDF file iconPDF (4253 KB)  

    The institutional framework recently set-up in Europe requires risk assessment and mitigation to be conducted for changes to, or the introduction of new, air traffic management (ATM) systems or services. In order to allow ATM service providers (ATMSPs) to perform such assessments, and to comply with regulatory requirements, a Task Force of European ATMSP, together with EUROCONTROL, has developed a...

  • Negligible Risk for European Railway Risk Assessments

    Publication Year: 2007 , Page(s): 20 - 25
    Save to Project icon | Click to expandAbstract | PDF file iconPDF (3888 KB)  

    The European Railway Agency (ERA) proposes a risk management process for substantial changes of the railway system. The suggested risk assessment framework states, that no risk analysis has to be carried out for system hazards with a so called negligible risk. However, the ERA recommendations do not give detailed information about what negligible risk means quantitatively or how it can be derived.... View full abstract»

  • Acceptable Residual Risk - Principles, Philosophies and Practicalities

    Publication Year: 2007 , Page(s): 26 - 31
    Save to Project icon | Click to expandAbstract | PDF file iconPDF (3681 KB)  

    Safety is typically demonstrated by identifying hazards, mitigating those hazards, and then by showing that the remaining risk is acceptable. This paper begins by setting out some principles for assessing tests of risk acceptability. It then categorises and examines existing methods of testing for risk acceptability against those principles, and finds that they fall short. A new measure of risk ac... View full abstract»

  • Putting Risk into Context

    Publication Year: 2007 , Page(s): 32 - 37
    Save to Project icon | Click to expandAbstract | PDF file iconPDF (3443 KB)  

    Many aspects of risk exist within any organisation and these will differ dependent on point of view. Such a view is known as a context. Each context is complex in its own right but also presents complex interactions with the others; this can be viewed in a similar manner to the standard systems issue of dynamic complexity (the whole being greater than the sum of the parts). Many techniques exist t... View full abstract»

  • Model-based Framework for Addressing Diversity, Usability and Reliability for Safety Critical Interactive Systems

    Publication Year: 2007 , Page(s): 38 - 43
    Save to Project icon | Click to expandAbstract | PDF file iconPDF (4002 KB)  

    This paper proposes a notation and an architecture for the management of failure on input devices for safety critical interactive systems. This management of failure is done by means of a reconfiguration of input devices configuration and interaction techniques. Such reconfiguration aims at allowing operators to still interact with the interactive system. In complement with this input device confi... View full abstract»

    The application of human factors is intended to ensure that people are integrated into the system design safely, effectively and reliably. As the benefits are recognised, human factors increasingly forms part of both contractual requirements and safety assurance for major programmes. Through the use of a case study, this paper discusses how the application of human factors engineering methods, tec... View full abstract»

  • Validation and Verification Techniques for EMC for Functional Safety

    Publication Year: 2007 , Page(s): 49 - 54
    Save to Project icon | Click to expandAbstract | PDF file iconPDF (4470 KB)  

    Safety systems must maintain low risks over their lifetimes. Where electromagnetic interference (EMI) could affect risks, an adequate level of electromagnetic (EM) performance is required. This is known as 'electromagnetic compatibility (EMC) for Functional Safety'. In most areas of safety system engineering, EM immunity testing is relied upon as the sole method of proving that EMI will not cause ... View full abstract»

    On 1 August 2005, a Boeing Company 777-200 aircraft, operating on an international passenger flight from Australia to Malaysia, was involved in a significant upset event while flying on autopilot. The Australian Transport Safety Bureau's investigation into the event discovered that "an anomaly existed in the component software hierarchy that allowed inputs from a known faulty accelerometer to be p...

    Publication Year: 2007 , Page(s): 66 - 71
    Save to Project icon | Click to expandAbstract | PDF file iconPDF (3500 KB)  

    EP2002 is an integrated "mechatronic" brake system that integrates mechanical, electronic and software components to provide load compensation, emergency brake, service brake and wheel slide protection. The design and development of the EP2002 system began at the end of the nineties. The introduction of the CENELEC standards on RAMS has changed the safety policy of K-BRS and in consequence the saf... View full abstract»

  • The Normal Operations Safety Survey (NOSS): Measuring System Performance in Air Traffic Control

    This paper discusses a field observation tool called the normal operations safety survey (NOSS). The air traffic control (ATC) system, through its equipment, procedures, and training, is designed to function in a particular manner. A system as complex and dynamic as ATC, however, does not always behave as designed. NOSS aims to provide a diagnostic of how the system actually behaves as opposed to ... View full abstract»

  • A Harmonised Risk Acceptance Criterion for Technical Systems in European Railways

    Publication Year: 2007 , Page(s): 84 - 88
    Save to Project icon | Click to expandAbstract | PDF file iconPDF (2969 KB)  

    In this paper a partial solution towards risk acceptance in European railways is proposed - namely for technical systems, which has already been formally agreed by the Union of European Railway Industries (UNIFE). As the proposal has a far-reaching impact on the safety of the railways, it is justified here using a wide variety of arguments, based on technical, normative, economic and legal conside...
