The invention provides a standardization and evaluation system and method based on cigarette batch data. Intra-group fluctuation and inter-group fluctuation can be considered at the same time. The method comprises the following steps: collecting steady-state data in a cigarette production process, determining a standard constraint form, and standardizing data in a group, a target value in the group and upper and lower limits according to the standard form of an index; and calculating the intra-group qualification rate and the inter-group qualification rate by utilizing the standardized intra-group mean value, the standard deviation and the upper and lower limit of the index, and synthesizing the final qualification rate of the batch data. The steady-state data is evaluated and scaled in proportion to fall into a specific interval, and obstacles brought by dimension and standard changes to data analysis and comparison are eliminated. And meanwhile, the difference of the smoothing effects of the inter-group mean values due to different sample sizes is considered, and the given inter-group standard range is reduced based on the sample sizes, so that the homogenization level of the cigarette production process is reflected more comprehensively.
