摘　　要：在应急响应系统(ERS)中,规则及规则推理用于确定应急事件的响应级别。当系统的规则库增加规则时,会出现冗余的规则,冗余规则的存在导致响应级别的判断不准确,影响推理的效率和准确性。针对该问题,提出一种规则的冗余检测方法,使规则库中的规则始终保持无冗余状态;同时,给出了冗余规则的处理方法。最后给出该算法的一个应用实例,结果表明该算法能快速检测出冗余规则,有效降低规则数目。Rule and rule reasoning are used to determine the response level of the event in emergency response system（ERS）.When a new rule is added to the rule base,redundant rule may appear;however,the existence of redundant rules will cause inaccuracy as the response level of the event is determined,and affect reasoning efficiency and the accuracy of reasoning.To solve the problem mentioned above,this paper proposed an algorithm for detecting redundant.It kept rules in rule base non-redundant and gave methods about how to deal with the redundant rules.Finally,shew an example using the proposed algorithm,the results indicate that the proposed algorithm can detect redundant quickly and reduce the number of rules effectively.
