摘　　要：介绍模糊推理机制中用于解决普通模糊匹配冲突问题的常用方法,包括海明距离和指数法。基于指数法提出类指数法和绝对值差积法,根据相似度的定义证明其正确性。算例比较结果表明,绝对值差积法的性能优于其他3种方法。This paper introduces the common methods for solving the collision problem of general fuzzy matching in fuzzy reasoning mechanism, including the Haming distance method and the exponent method. It presents the exponent-like method and the absolute value difference and product method based on the exponent method. The two methods are improved to be correct according to the definition of similarity. Numerical example comparison results show that the absolute value difference and product method has higher performance than the three other methods.
