摘　　要：针对带钢质量评价属性多、指标多的特点,提出了带钢质量综合评价的属性识别模型。依据属性识别理论中有关属性集、属性测度、有序分割类等基本概念,建立了质量等级属性集并计算出带钢质量影响因素的单属性测度和综合属性测度。以置信度准则和评分准则为判别准则,根据置信度准则进行带钢质量的等级评定。同一等级的带钢质量差别由评分准则来区分。实例表明,该模型计算简便,易于计算且具有一定的推广性。Aiming at features of strip steel＇s quality evaluation problem with multi--attributes and multi--indexes, a strip quality comprehensive evaluation attribute recognition model was pro- posed. Based on the basic concepts of attribute recognition theory, for example, attribute set, attrib- ute measure and ordered partition class, a quality level attribute set was established and the attribute measure of single index and comprehensive attribute measure were calculated. Confidence criterion and grading criterion were as discriminant criteria,the quality level of strip steel was evaluated accord- ing to confidence criterion, the quality differences of the same level of strip steel were distinguished according to grading criterion. Experimental results show that the performance of this new method is accurate and effective.
