中文摘要：

提出了一种基于概念分解的政策精化方法，将政策的精化归结为对概念的分解，依据本体论中的概念结构将政策中较高层的概念转换为较低层的概念，从而实现政策的精化。给出了该精化算法的步骤，并通过一个案例演示了该方法的执行过程，最后与其他几种政策精化算法进行对比分析，指出该算法的优缺点。

英文摘要：

This paper proposed a concept decomposition-based policy refinement method, thus, the process of policy elaboration could be seen as a process of concept decomposition, which was aimed at transforming the concepts at higher levels into concepts at lower levels. Gave the steps of the algorithm and showed the process of execution by a case demonstration. In the end, gave the advantages and disadvantages of this method by comparing it to other methods.
