[0098] S1102: Determine the evaluation criteria for each process quality factor. Please see the following description.

[0099] S1103: Determine the primary importance of each process quality factor to the cigarette wire production process.

[0100] As an embodiment, the importance is expressed in the form of weights. The weights of various process quality factors can be determined using existing weight calculation methods.

[0103] P1: Determine the process parameters related to each process quality factor based on the actual production situation. Specifically, the process parameters related to each process quality factor can be determined based on the management requirements of the above process quality factors.

[0104] For example, for the quality control of sugar and spices, the process parameters include the labeling quality of sugar and spice transfer tanks and barrels; whether the sugar and spices are within the validity period; whether the labeling of the tanks being used in production is consistent with the production brand specifications; and whether there is stirring for more than the preset time before the flavors and spices are used.

[0105] The scattered tobacco flakes and shredded tobacco produced during the production process should be added in the same process and batch, and the process parameters should be collected using the following method:

[0106] Q1: Determine whether the scattered position and weight of tobacco leaves and shreds meet the requirements.

[0107] As an embodiment, the scattering locations of tobacco pieces and shredded tobacco are mainly where the cigarette box is opened, the tobacco pieces are placed in a dehumidification box, and the corresponding locations where they are lifted after loosening and dehumidification. The scattering weights at these three locations are 0.1-0.3 kg / box, 5-10 kg / batch, and 6-15 kg / batch, respectively.

[0108] Q2: Determine whether the time point at which tobacco flakes and shreds scattered at different locations return to the production process is accurate.

[0110] Q3: Detect the types of tobacco flakes and shreds in the same batch to determine whether all scattered tobacco flakes and shreds have returned to the same batch of production materials.

[0111] As an example, in the cigarette production process, scattered tobacco flakes and shredded tobacco are mainly recovered by negative pressure collection, followed by laser impurity removal to sort out the impurities, and after confirming that there are no impurities, they are added to the same batch of production materials through negative pressure.

[0112] As an embodiment, each of the above steps corresponds to a process parameter. As another embodiment, a comprehensive value is calculated using the values ​​obtained in all the above steps as a process parameter.

[0113] P2: Determine the second importance of each process parameter to the process quality factor.

[0115] P3: Determine the evaluation criteria for each process quality factor based on all process parameters and their second importance.

[0116] Therefore, the process quality evaluation standard includes the meaning, scoring standard and weight of each process parameter in each process quality element, the scoring standard and weight of all process quality factors for the cigarette silk production process, and the process quality grade to which the score of the cigarette silk production process belongs.

[0117] S120: During the cigarette cutting production process, process parameters involved in process quality evaluation are collected in multiple collection cycles.
