    Conceptual modelling, appropriate at representing and manipulating abstract underdeveloped constructs, is applied to manufacturing flexibility. The results is a network of concept nodes that can provide users (or specifiers) with a more formal means to develop flexibility requirements in terms of machine and system features. The paper examines the basic concepts of flexibility and translates them ... View full abstract»

    The authors describe their experience gathered over a number of years into prototyping an AI-based knowledge-based environment for modelling and simulation (KEMS). A crucial aspect of the component-based representation behind KEMS is that of knowledge acquisition. A knowledge acquisition module (KAM) has been developed which uses a seminatural language frame-representation language (FKRL) for enco... View full abstract»

    The general background of modelling and simulation is examined, mostly from the point of view of potential predictive capability. Linguistic modelling, a branch of qualitative modelling is outlined which has been evolved especially for the representation of human activity situations, not amenable to mathematical analysis. This modelling technique involves the use of natural language suitably proce... View full abstract»

    Investigates the possibility of building an integrated, knowledge based simulation model of a manufacturing system. The structure of the system is modelled in the IDEF0 format. However this structure is developed within a software environment supported by the STEM discrete event simulation package. This latter package runs in the ENVOS LISP/LOOPS AI workstation environment, and whilst it is primar... View full abstract»

    The National Grid Company's (NGC's) supergrid consists of about 200 substations inter-connected by over 7000 km of transmission lines. The supergrid can suffer failures like any other complex system. The system is continually monitored by protection systems which automatically open circuit-breakers to isolate the affected items of plant. Low level messages reflecting these switching events and som... View full abstract»

  • A qualitative circuit simulator

    Publication Year: 1991, Page(s):5/1 - 5/3
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (168 KB)

    Describes some current work aimed at producing a system which will act as an assistant to engineers doing failure mode effects analysis (FMEA). The particular interest in FMEA is in the design of electrical circuits in an automotive context. In the FMEA application, it is important that faults such as short and open circuits (changes in the topology of the circuit) and their effects can be located... View full abstract»

  • Explaining simulation models

    Publication Year: 1991, Page(s):7/1 - 7/2
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (52 KB)

    Explanations are provided by expert systems to reassure their users of the validity of conclusions and of the relevance of queries. This paper, which addresses explanation in the context of simulation models, describes an expert system that is entirely devoted to explanation. The purpose of the system is to explain the results, i.e. the quantitative behaviour, of simulation models. In doing so, it... View full abstract»
