摘要
分析了一类具有离散时间分析和延时特性的离散系统定性仿真方法。通过将离散系统的不精确或不完备知识抽象为定性值、规则和约束，运用定性差分方程形式定性建模，结合QSIM算法中约束传播定量信息进行定性定量集成仿真。并给出仿真实例。
The qualitative simulation of a kind of discrete system with discrete-time analysis and time-lag attribute is analyzed. By abstracting the imprecise and incomplete knowledge of discrete systems into qualitative values, rules and constraints, with the qualitative model constructed by qualitative difference equations, and by combining constraint-propagation algorithm in QSIM, the qualitative-quantitative simulation and such an example are carried out.
