Abstract:It is natural to combine AI applications and simulations using object-oriented approach as object-oriented systems appear to be efficient and flexible in building knowledge-based systems and coping with the complexity of system simulation. In this paper, we discuss how object-oriented approach contributes to solving complex system simulation problems and how this approach can be applied to the simulation of hydroelectric power systems. A brief introduction is firstly presented to compare conventional system simulation technology with object-oriented approach. Two important issues in object-oriented approach to complex system simulation, i.e., system modelling and reasoning about the behaviours of the rule-based reasoning are then presented by examining an object-oriented simulation system architecture in which rule-based reasoning and object-oriented message passing are combined. The transient simulation of water turbine in a hydraulic power system is used as an example to illustrate the ideas. our object-oriented simulation system was built using an object-oriented system development tool, GoldWorks II on a Macintosh IIci. finally, some of the problems in developing our object-oriented simulation system are discussed.
