基于多准则模型的棉纤维评价研究OACSTPCD

In order to realize the reasonable application of high-capacity fiber detection index in cotton fiber evaluation and provide references for subsequent cotton blending,a cotton fiber quality evaluation model based on experimental design(DoE)method was established.Firstly,1 000 cotton samples were randomly selected,and the quality index of cotton fiber was given different weights by CRITIC weight method.The TOPSIS score was used as the output variable to construct an experimental plan.Two level partial factor experiments were conducted according to the experimental plan to establish an evaluation model.Finally,the fitting degree and residual of the constructed evaluation model were analyzed,then the correlation among this model and three models including SCI,FQI,and MIAHP were discussed.The results showed that the multi-factor interaction of micronaire value×breaking tenacity,breaking tenacity×number of impurity particle×impurity area ratio,upper half mean length×breaking tenacity×impurity area ratio had significant influences on cotton fiber quality.This model had a better consistency with the existing evaluation model.The cotton fiber quality evaluation model could be realized by the quantitative evaluation model of cotton fiber quality.
