Rule-based Simulation Control in an Object-oriented Environment

概要

In order to develop a training simulator^*,we have developed Tec++,an object-oriented expert system shell.The system employs knowledge objects by combining object-oriented functionality,to represent the entities which exist in the simulated environment,with rule-based reasoning techniques,to describe the behavior of the entities in the simulation.In most object-oriented systems,object control is handled by an embedded scheduling mechanism.This method limits the flexibility in the user's control of objects.Simulation of a real-world system requires the user to accurately control the occurrence of simulated events.In this object-oriented shell,delegation of control among the objects is handled by a knowledge object.The rules of this knowledge object,the Scheduler Object,are used to govern which object is in control of inferencing at any time.Additional scheduling rules can be defined to control the objects in the simulation, thus giving the user more flexibility in overall object and event manipulation.
