    A good model is essential in simulating and analysing a system satisfactorily. This paper proposes a new computer-aided modelling methodology to construct parsimonious models for dynamic physical systems. A set of domain-independent modelling principles and domain-dependent modelling constraints has been formulated to guide parsimonious model construction. Models and the knowledge base for the enh...

  • Non-causal versus causal qualitative modelling and simulation

    Qualitative models of dynamical systems fall into noncausal or causal approaches. The noncausal approach is widely used in part because traditional physics describes phenomena by means of symmetric functional relations. It supports the idea that causality can be ignored or inferred from the model itself. Nevertheless, when people explain how things work, they use causal relations. Representing cau...

    To build model-based systems capable of emulating the scientist's or engineer's way of reasoning about a given physical domain requires methods for automating the formulation or selection of a model which adequately captures the knowledge needed for solving a specific problem. To find and exploit such models requires the use and integration of different kinds of knowledge, formalisms and methods. ... View full abstract»

  • Restriction of qualitative models to ensure more specific behaviour

    Publication Year: 1993, Page(s):133 - 144

    This paper discusses methods for applying restrictions to qualitative models of physical systems in order to ensure more specific behaviour. Restriction is performed by adding constraints; directly on exogenous parameters, and indirectly on nonexogenous or dependent parameters. The former are called primary restrictions, and the latter are called derived restrictions. We show the connection betwee... View full abstract»

    A concept for distributed control systems is outlined. The concept is based on a plant database containing descriptions of the plant and the control system. The database is object-based and supports multiple view of an objects. A demonstrator is presented where a DCS of this type is emulated. The demonstrator contains a number of control, monitoring and diagnosis applications that execute in real ... View full abstract»
