The invention discloses a cigarette production process stability monitoring method. The monitoring method sequentially comprises the following steps: 1, classifying variables in a cigarette production process; 2, conducting quantitative characterization on the classified variables; 3, implementing single-variable monitoring, adopting different monitoring models in accordance with different variable types; and 4, implementing multi-variable monitoring, wherein the multi-variable monitoring includes two parts, namely process comprehensive monitoring and batch comprehensive monitoring, a process stability monitoring comprehensive index model is adopted and a batch stability comprehensive monitoring index model is adopted for the batch comprehensive monitoring. The cigarette production process stability monitoring method disclosed by the invention not only can detect the minimal stability variable in the production process but also can detect processing stability and batch comprehensive stability of the process, so that the method offers strong support for improving cigarette production and enhancing the stability of product quality.
