基于模糊评价树的中药材定级估价模型

Classification and Evaluation Model of Traditional Chinese Medicine Based on Fuzzy Evaluation Tree

中药材定级估价是中药材产、供、销、储、用和监督管理过程中的基本准则。基于模糊数学理论建立了一个模糊评价树模型。用节点刻画评价指标记录评价数据,用树上的边记录评价权重,并在节点和边上定义合理的模糊评价算子,进行多级综合评价对中药材定级估价。评价过程考虑定性与定量信息,更加客观自然且自动化程度高,评价结果科学合理且信息量大。讨论了该模型的计算复杂度,给出了中药材定级估价的一个实例,结果表明该评价模型客观高效。

The grading and evaluation of traditional Chinese medicine is a basic principle in the process of production, supply, sale, storage, use, supervision and management of traditional Chinese medicine. Based on the theory of fuzzy mathematics, a fuzzy evaluation tree model is established;the evaluation data are recorded by the evaluation index described by the node, and the evaluation weights are recorded by the edges of the tree. A reasonable fuzzy evaluation operator is defined on the node and the edge to carry out multi-level comprehensive evaluation of traditional Chinese medicine. The qualitative and quantitative information is considered in the evaluation process, which is more objective, natural and highly automated. The evaluation results are scientific, reasonable and informative. The calculation complexity of the model is discussed. An example of the evaluation of Chinese herbal medicine is given, and the results show that the evaluation model is objective and efficient.
