一种基于粗糙集的纺织企业纱线质量评价模型

Evaluation Model of Textile Yarn Quality Based on Rough Set Theory

纺织企业对纱线质量进行客观评价具有重要现实意义。针对现有评价体系过度依赖于主观经验判定的缺点,将粗糙集理论引入纱线质量评价,提出了评价指标离散化算法并构建了评价度量函数,在此基础上建立了基于粗糙集的纱线质量评价模型。实验结果表明该模型实现简单,运行效率高,为企业质量管理者进行决策提供了更加客观的数据支持。

It has important practical significance for textile enterprises to evaluate objectively the yarn quaiity. According to the disadvantage the existing evaluation system is overly dependent on subjective experience to determine, this paper put rough set theory into the evaluation of yarn quality,and put forward the discrete algorithm of the evaluation index and constructed the evaluation metric function. On this basis, the yarn quality evaluation model was established based on rough set. The experimental results show that the model is simple and high efficient,and provides more objective data for the quality manager to carry on the decision making.
