基于集对分析的双级真空挤出机性能评价

摘要

This paper presents a comprehensive quality evaluation method of double stage vacuum extruder based on the set pair analysis. Two different aspects are the scale to measure the merits of the object, makes the decision more comprehensive and accurate. It uses the improved 1-9 scaling method to determine the weight of the evalua⁃tion index, the importance of the indicators can be more refined, to avoid the disadvantages of the traditional 1-9 scaling method.%提出了一种利用集对分析双级真空挤出机综合质量评价方法。以同一度和对立度两个方面作为尺度衡量评价对象的优劣，使决策更加全面、准确。采用改进的1-9标度法确定评价指标的权重，指标的重要性可以更加细化，避免了传统1-9标度法确定的权重数值相差太大的缺点。
