  • Adaptable Modelling of Electrical Systems 
    Price, Chris; Snooke, Neal; Lewis, Stuart (2003-08)
    Much research in model-based reasoning has concentrated on the use of a single, usually qualitative, level of modeling. This is less than ideal for many engineering applications, where the amount of knowledge available ...
  • Automated Failure Effect Analysis for PHM of UAV 
    Downes, Clive; Snooke, Neal; Price, Chris; Aspey, Carol (2008-04-01)
    The ASTRAEA project is a £32M UK initiative to develop the safety case for unmanned aerial vehicles flying in commercial airspace. It is addressing both the issue of what needs to be covered by such a safety case, and how ...
  • Automated Multiple Failure FMEA 
    Taylor, Neil; Price, Chris (2002-04)
    Failure mode and effects analysis (FMEA) is typically performed by a team of engineers working together. In general, they will only consider single point failures in a system. Consideration of all possible combinations of ...
  • An Automated Software FMEA 
    Price, Chris; Snooke, Neal (Research Publishing Services, 2008-04-03)
    The concept of software failure mode and effects analysis (FMEA) has grown in attractiveness over recent years as a way of assessing the reliability of software. Like its hardware counterpart, software FMEA is immensely ...
  • Automating Mechanical FMEA Using Functional Models 
    Hughes, Nigel; Chou, Enxi; Price, Chris; Lee, Mark (1999-05)
    This paper considers the application of functional modelling to the automated production of FMEAs for mechanical systems. We consider how a functional model can be generated algorithmically from the geometric and assembly ...
  • Challenges for qualitative electrical reasoning in automotive circuit simulation 
    Snooke, Neal; Price, Chris (1997-06-03)
    Qualitative reasoning about electrical systems has reached a level of achievement which allows it to be used for applications on realistic automotive circuits. The type of circuits for which it is most effective can be ...
  • Combining Functional and Structural Reasoning for Safety Analysis of Electrical Designs 
    Price, Chris; Pugh, Dave; Snooke, Neal; Hunt, John; Wilson, Myra (1997)
    Increasing complexity of design in automotive electrical systems has been paralleled by increased demands for analysis of the safety and reliability aspects of those designs. Such demands can place a great burden on the ...
  • Computer-Based Diagnostic Systems: Computer-Based Troubleshooting 
    Price, Chris (Springer, 1999)
    Diagnostic systems are among the most successful applications of knowledge-based systems (KBS) technology. This is true both in terms of the number of applications built, and in terms of the benefits which such systems ...
  • Functional decomposition for interpretation of model based simulation 
    Bell, Jonathan; Price, Chris; Snooke, Neal (2005-05)
    Description of system function is already in use as the basis of an approach to interpretation of the results of simulation in design analysis, allowing an automated design analysis tool to generate a textual report detailing ...
  • Fuzzy Order-of-Magnitude Based Link Analysis for Qualitative Alias Detection 
    Shen, Qiang; Boongoen, Tossapon; Price, Chris (AAAI Press, 2011-09-27)
    Numerical link-based similarity techniques have proven effective for identifying similar objects in the Internet and publication domains. However, for cases involving unduly high similarity measures, these methods usually ...
  • Hierarchical Functional Reasoning 
    Snooke, Neal; Price, Chris (1998-11-23)
    This paper discusses the use of hierarchies of function in reasoning about automotive electrical systems. Such hierarchies enable more powerful reasoning for applications such as diagnosis, failure mode and effects analysis, ...
  • Identifying Design Glitches through Automated Design Analysis 
    Price, Chris; Snooke, Neal; Ellis, David (1999-01)
    Engineers have developed a number of design techniques in order to detect problems in their designs, such as yellow-boarding, FMECA, FTA and sneak circuit analysis. Concurrent engineering demands that all such design ...
  • A language for functional interpretation of model based simulation 
    Bell, Jonathan; Snooke, Neal; Price, Chris (2005-08)
    Functional modeling is in use for the interpretation of the results of model based simulation of engineered systems for design analysis, enabling the automatic generation of a textual design analysis report that expresses ...
  • A layered approach to automated electrical safety analysis in automotive environments 
    Price, Chris; Snooke, Neal; Lewis, Stuart (2006-06)
    Software support for the automotive electrical design process is vital, as many of the safety analysis tasks needing to be carried out, while complex, are repetitive and time consuming. Such support is required throughout ...
  • Model-based systems in the automotive industry 
    Price, Chris; Struss, Peter (2004-01)
    The automotive industry was the first to promote the development of applications of model-based systems technology on a broad scale and, as a result, has produced some of the most advanced prototypes and products. In this ...
  • Qualitative Futures 
    Price, Chris; Trave-Massuyes, Louise; Milne, Rob; Ironi, Liliana; Forbus, Kenneth; Bredeweg, Bert; Lee, Mark; Struss, Peter; Snooke, Neal; Lucas, Peter; Cavazza, Marc; Coghill, George (2006-12-04)
    This paper reviews the state of the art in model-based systems and qualitative reasoning, and considers where the field will be in twenty years time. It highlights six areas where developments in model-based systems in ...
  • Whole Lifecycle Electrical Design Analysis 
    Snooke, Neal; Price, Chris; Ellis, David (2002-06)
