摘要
通过使用集合的基本概率定义出上限、下限概率,形成信度;通过隶属函数定义模糊集合的包含度、相交度,使信度理论在模糊集合得以扩张,得到了利用不确定性及模糊性的一个合理的推理方法。在此基础上,采AND/OR/COMB树推理开发了一个审定损害的专家系统。
To define upperand low er probabilities by using the basic probability ofset, and then form thebelief. To define the inclusion degree and intersection degreeoffuzzy setthrough m em bership function,and m ake the belieftheory can be spread in fuzzy set and then w egota reasonable inference ofusing uncertainty and fuzziness. On the base, w e inferred and developed an expertsystem to define upper and low er probabilities by using the basic probability ofsystem ofexam ining dam age by using AND/OR/COMB Tree.
