基于AHP-CRITIC组合赋权+TOPSIS方法的烟叶复烤工艺参数评价

Evaluating technical parameters for tobacco redrying using AHP-CRITIC combination weighting+TOPSIS method

为研究复烤过程中工艺参数设置对烟叶复烤质量的影响,针对隧道网带式复烤设备的工艺参数提出了AHP-CRITIC组合赋权+TOPSIS方法,并通过该方法对K326品种烟叶复烤过程的工艺参数进行综合评价。结果表明:①干燥区工艺参数、来料特性参数和车间环境参数3个一级指标的权重占比较大,车间湿度、干燥一区热风温度等10个二级指标的权重占比较大,为影响烟叶复烤质量的主要因素。②相比于单一赋权法,AHP-CRITIC组合赋权+TOPSIS方法的平均相对误差及欧式距离合计值均最小,说明该方法得到的结果可以准确地评价复烤工艺参数。③综合得分低于80分评价对象的加工方式存在不足,通过计算其工艺参数的详细得分,可判断出导致烟叶复烤质量产生波动的指标。

The AHP-CRITIC combination weighting+TOPSIS method was developed to investigate the effects of technical parameters on the quality of tobacco redried by a current apron conveyor redrying method.The technical parameters for redrying flue-cured tobacco variety K326 were comprehensively evaluated by the developed method.The results showed that:1)The weights of three first-level indexes,namely technical parameters in the drying section,tobacco characteristic parameters and workshop environment parameters,and those of ten second-level indexes,including workshop humidity and hot air temperature in the first drying section,etc.,accounted for a relatively large proportion influencing the redrying quality of tobacco.2)Compared with the single weighing method,both the average relative error and the total Euclidean distance value of the AHP-CRITIC combination weighting+TOPSIS method were the smallest,indicating that the results obtained by this model could truthfully evaluate the technical parameters of tobacco redrying.3)There were deficiencies in the evaluated objects with an overall score below 80.By calculating the detailed scores of the technical parameters,it was possible to identify the specific indexes responsible for the quality fluctuations in the redried tobacco.
