摘　　要：针对螺杆挤出机综合评价的问题,提出一种基于层次分析法(AHP)和模糊综合评价法的综合性能评估体系。目的是确保产品质量与生产效率的提高,同时为设备的升级改造和绿色制造提供依据。通过建立层次结构模型、构建判断矩阵并进行一致性检验以及计算各评价指标的权重,形成系统化的评价方法。选取一种同向双螺杆挤出机作为案例,运用模糊综合评价法进行量化分析。结果显示,该型号挤出机在机械性能、经济性和生产效率方面表现良好,但在可靠性和环境友好性方面存在不足。综合评价结果认为,该型号挤出机综合评分较好,且实际情况与评价体系得出结论基本一致,证明了评价体系的有效性。最后,建议未来可通过扩大样本量和技术整合来进一步完善评价体系。The study presents a novel comprehensive performance evaluation framework for screw extruders,utilizing a combination of the analytic hierarchy process(AHP)and fuzzy comprehensive assessment methodology.The objective is to enhance product quality and production efficiency while providing a theoretical foundation for equipment modernization and eco-friendly manufacturing practices.The systematic approach involves the development of a hierarchical model,construction of a pairwise comparison matrix,execution of consistency validation,and determination of the relative importance of various evaluation criteria.A co-rotating twin screw extruder was selected as a case study and quantitatively analyzed using the fuzzy comprehensive evaluation method.The results show that this model of screw extruder performs well in terms of mechanical performance,economy and production efficiency,but is deficient in terms of reliability and environmental friendliness.The comprehensive evaluation results conclude that the model screw extruder has a good overall score and the actual situation is basically consistent with the conclusions drawn from the evaluation system,which proves the effectiveness of the evaluation system.Finally,it is suggested that the evaluation system can be further improved in the future by expanding the sample size and technology integration.
