摘要
针对铜闪速熔炼过程中操作模式库庞大导致最优操作模式搜索速度慢的问题,提出了基于柯西不等式的操作模式分级快速匹配策略。先利用主元分析法设置属性权重,再采用柯西不等式进行相似性的初级匹配,得到相似操作模式集,次级匹配只需要在相似操作模式集中进行,降低计算的繁琐性,提高了匹配效率。最后通过UCI数据与实际生产数据结果分析验证该方法的有效性。
Considering the rawback of low speed of pattern matching caused by huge pattern case for copper flash smelting process, Cauchy-Schwarz inequality based operational pattern two-grade fast matching strategy is developed. Using PCA, the attributes weights are set firstly, then the Cauchy-Schwarz inequality is introduced to the similarity criteria of first matching process, and extracts the similar operational patterns. The secondary matching process is completed only in the similar operational patterns, it can be used to reduce the computational complexity and accelerate the efficiency. The application results of UCI data and the actual data are given to verify the effectiveness.
