基于模型的定性仿真的研究现状

Current Research Status of Model-based Qualitative Simulation

基本方法定性推理是Al的重要分支。定性的含义是指推理中使用的信息和推理的结论都是定性的(本质上是离散的而非连续的)。定性推理的目的是对物理现象作解释且解释的粒度较粗,具有较高的知识层次,是对物理现象宏观行为的描绘[lJ;它与实际物理系统的关系极为密切,从而可根据实际物理背景验证Al及定性推理理论和方法的正确性,便于实现可用的系统。在信息量巨大,数据繁多。

Model-based Qualitative Simulation (QS) is one of the most important research areas of qualitative reasoning(QR) ,it is considered as the foundation of most applications of QR. In this paper,the QS methods are generalized. Its originality ,development and current research status are analyzed systematically. The issues that still exist in QS and the tendency of QS research are also discussed.
