摘　　要：中药滴丸生产周期较长,生产数据较少,而且无法得到使得滴丸含水量稳定的相关工艺参数的控制指标,采用蒙特卡洛方法对滴丸含水量进行仿真研究.仿真过程中利用粗糙集对影响滴丸含水量生产工艺参数集进行属性规约,然后用SVM对滴丸含水量建模,基于所建模型采用蒙特卡洛方法对含水量进行了仿真.仿真求得了滴丸含水量的均值和方差,仿真结果表明:当浸膏含水量控制在比实际更小的范围内,滴丸含水量稳定性可较好的控制.Chinese medicine pills has a longer production cycle and less production data, and we can＇t get the guideposts of relevant parameters which stabilizes the pills moisture. The Monte Carlo method is taken for simulation study of pills moisture. In the process of simulation, rough set is used for attribute reduction of production parameter set which affects pills moisture, then the model of pills moisture is built using SVM, and the Monte Carlo method is taken for simulation of pills moisture based on this model. The simulation gets the mean and variance of pills moisture and it indicates that the pills moisture can be more stabilized when the extract moisture is controlled in a smaller range than the actual.
