Qualitative Simulation of a Kind of Discrete System
Zonghai Chen · Acta Simulata Systematica Sinica · 2001
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.
