摘要： 在知识工程的研究中,如何表示不确定性是一个非常重要的问题。本文讨论了在知识工程中用来处理不确定性的各种模糊度量方法,并分析了它们之间的关系。这对于理解以及如何选用一个合适的不精确推理模型是十分有益的。

Abstract: In making research on knowledge engineering, to represent uncertainty is very important. This paper discusses fuzzy measures adopted to deal with uncertainty and analyzes relationships among classes of fuzzy measures, which very much helps understand and select an inexact reasoning model.
