在设计模糊逻辑系统时,如何实现其对输入噪声的鲁棒性是一个首要的问题,相应地如何很好地分析其对输入噪声的鲁棒性(也称敏感性分析)也就成了一个重要问题.使用统计的方法,对常见的模糊推理方法进行了敏感性分析.首先以均值与方差为基础,提出了2个模糊集的ε统计相等的概念;随后导出了常见的模糊推理方法的统计敏感性,这包括链接模糊推理与多规则模糊推理.与前人相关工作不同的是,更着重于模糊推理的方差分析,这一方法从数理统计的角度来看能更好地揭示模糊推理本质的敏感性.

Robustness of input noise is an important issue when designing a fuzzy logic system. In this paper, a statisticsbased method is introduced to analyz e the sensitivity of various popular fuzzy reasoning methods. Using the new conce pt of εstatisticalequalities, the statistical sensitivity between two f uzzy set s is analyzed based on their means and variances. Then the statistical sensitivi ties of various popular fuzzy reasoning methods are derived, including syllogist ic fuzzy reasoning and fuzzy reasoning with multiple rules. Different from other research work, the variance analysis of fuzzy reasoning is particularly emphasi zed to better reveal the sensitivity of fuzzy reasoning from a statistical persp ective.
