基于最优组合赋权的打叶复烤过程烟叶可用性研究

目的：进一步提高打叶复烤过程中烟叶可用性评价结果的可信度和科学性，以提升卷烟工业企业所购烟叶的价值。方法：提出一种基于矩估计理论的最优组合赋权评价方法对烟叶化学成分可用性进行评价。以主客观权重为基础，组合权重与主客观权重偏差最小为目标，求解主客观权重的相对重要性系数从而确定化学指标的最优组合权重；结合隶属度函数，以烟叶化学成分指标为数据集计算烟叶化学成分可用性值，进而对打叶复烤过程中烟叶可用性进行评价；并以麒麟复烤厂打叶复烤成品烟叶作为分析对象。结果：该方法能够充分考虑主客观因素，使得赋权结果和评价结果与实际情况更加吻合。结论：通过矩估计理论组合赋权能够对打叶复烤过程中烟叶可用性进行更加合理、科学的评价。

Study on tobacco leaf availability during threshing and redrying process based on optimal combination weighting

Objective: In order to further improve the reliability and scientificity of tobacco usability evaluation results in threshing and re-drying process, and to enhance the value of tobacco purchased by cigarette enterprises. Methods: An optimal combination weighting method based on moment estimation theory was proposed to evaluate the availability of chemical components in tobacco leaves. First, based on the subjective and objective weights, with the objective of minimizing the deviation between the combined weights and the subjective weight, the relative importance coefficient of the subjective weights and objective weight was solved to determine the optimal combined weights of chemical indexes. Second, combined with the membership function, the chemical composition index of the tobacco leaves was used as the data set to calculate the availability value of the chemical composition of the tobacco leaves. Furthermore, the usability of tobacco leaves during threshing and re-drying process was evaluated. Finally, the finished tobacco leaves from the Qilin re-drying plant was taking as the object of analysis. Results: This method can fully consider subjective and objective factors, making the weighting results and evaluation results more consistent with the actual situation. Conclusion: The combination of weighting by moment estimation theory can make a more reasonable and scientific evaluation of tobacco leaf usability during threshing and redrying process.
