In order to achieve a comprehensive evaluation of ash characterization of burning cigarette and make the evaluate results concrete, the gray scale, crack rate, shrinkage rate, width of char line, and uniformity of char line measurement results of 49 cigarettes were used as the primitive variables. Firstly, K-means clustering and fuzzy discriminant analysis were used to convert the primitive variables into concrete score data, then the weight of each indicator was assigned by critical weighting method, and a comprehensive evaluation method was established. The results indicated that converting the primitive variables into scores ranging from 60 to 100 with an average value of around 80 could make the evaluate results concrete and consistent with cognitive habits. The weight of the five indicators, from high to low, was as follows: crack rate (0.27) > shrinkage rate (0.25) > gray scale (0.18) > uniformity of char line (0.16) > width of char line (0.14). The comprehensive ash characterization of burning cigarette could be divided into three levels: excellent, good, and poor, the score range of each level was (85, 100], [75, 85], and [60, 75), respectively, the comparison of bar charts of representative cigarettes of different levels proved that the comprehensive score could objectively reflect the advantages and disadvantages of the ash characterization of burning cigarette.
