摘　　要：为了维护卷烟配方的稳定,卷烟工业企业需要定期对配方进行维护,即对配方中的单料片烟进行补充或替换。针对卷烟配方维护问题,提出了一种基于互信息的卷烟配方维护方法,分析了中烟工业公司提供的卷烟配方数据,计算单料片烟在配方中的共现频率,进而计算出单料片烟两两之间的互信息,通过互信息挖掘出单料片烟之间的配伍性,进而完成配方维护过程。结果表明:①基于互信息的卷烟配方维护方法可以很好地还原实际生产过程中配方维护的过程。②基于互信息的卷烟配方维护方法以配伍性作为考虑因素,缺失单料片烟在推荐列表中排名平均数为6.585,可以在配方维护过程中保证新配方具有良好的配伍性。③提出的衡量算法效果的度量指标解决了数量不对等的单料片烟替换过程的效果度量问题,可以衡量在实际生产过程中更为常见的数量不对等的多对多的单料片烟替换问题。In order to maintain the consistency of cigarette blending for regular cigarette maintenance,it is necessary to supplement or substitute single-grade tobacco strips in the blend from time to time.Therefore,a cigarette blend maintenance strategy based on mutual information was proposed.The co-occurrence frequency of single-grade tobacco strips in a cigarette blend and the mutual information between single-grade tobacco strips in pairs were calculated after analyzing the blending data.The mutual information allowed the compatibility between the single-grade tobacco strips to be assessed for blend maintenance.The results showed that:1)This blend maintenance strategy could successfully restore a target blending in the actual production process.2)This approach effectively took compatibility as a consideration factor to ensure that the new blend had good compatibility in the blend maintenance process with the rank average of missing single-grade strips of 6.585.3)The proposed measurement index and the associated effect algorithm solved the challenge of effect measurement during single-grade tobacco replacement with unequal quantity.It could also measure the batch-to-batch single-grade tobacco replacement with unequal quantity in actual production process.
