most process parameter alarm threshold optimization method didn't consider the influence of operator. Therefore
a new process alarm threshold self-adaptive optimization method considering operator's influence with the theory of human factors is introduced in this paper. Firstly
APRIORI algorithm is used to mine the association between alarm events and operational events. Secondly
based on online alarm data
fuzzy reasoning obtains human factor comprehensive index. The weights of false alarms and missed alarms are calculated
and an alarm threshold optimization objective function is established. Industrial examples verify the effectiveness of the method.
