摘要: 简要分析精毛纺前纺工艺的特点,针对其粗纱质量指标的重要性和涉及到13个工艺参数给企业工艺设计和生产质量控制带来困难这一问题,基于采集到的某精毛纺企业50组历史生产数据研究,对其实现粗糙集数据分析,在Rosetta环境下分别得到粗纱CV值(R1)和单重(R2)的约简核,分别提取出工艺参数和R1、R2之间的36条和28条潜在知识规则,并以其中某一批毛条为例,以约简后的属性组织案例与R1相关的第12条规则吻合;同时将粗糙集引入基于案例推理中,建立了基于粗糙集的案例库索引,实现了基于规则推理和基于案例推理的有效结合,为工艺设计和产品质量预报及控制提供指导。

Abstract: The character of worsted fore-spinning process has been briefly analyzed.As the roving quality′s importance and involving many parameters,the quality′s control and process parameters′ design become difficult.Based on 50 groups of historical data gathering from a worsted mill,rough set data analysis(RSDA) was actualized to get the reduced cores of roving unevenness(R_1) and weight(R_2) in Rosetta environment.According to R_1 and R_2,36 and 28 potential knowledge rules were got respectively.Take a certain group of tops as an example,the twelfth rule related R_1 was completely in accord with the case composed by the reduced attributes.Meanwhile RS was inducted to case-based reasoning(CBR) to establish the case index storehouse.It realized the effective union of rule-based reasoning(RBR) and CBR,in order to guide the craft design and product quality control.
