针对配料生产过程大惯性、高度非线性以及对象模型不确定性等特点，提出一种从仿人决策思维的规律出发，基于半模糊语意区间表达的模糊知识，用ＩＤ５Ｒ算法来获取控制规则的知识自动提取方法．仿真结果表明，用此方法的计算开销比ＩＤ３ 算法小，且能获得相同的定性控制规则．
Aiming at the characteristics of large inertia, high nonlinearity and uncertainty of the object model in ingredients production process, this paper proposes a method of ID5R algorithm based on the fuzzy rules expressed in semi-fuzzy semantic interval to get the rules of control rules Automatic extraction method. The simulation results show that the computational cost of this method is smaller than that of ID3, and the same qualitative control rules can be obtained.
