基于AHP和加权灰色关联分析的并条机设计评价研究

目的 为客观评价定性指标因素对并条机设计的影响，降低人在决策设计方案过程中的主观性偏差，建立将并条机定性指标转换为定量指标，并得出最佳设计方案的评价模型。方法 采用层次分析法（Analysic Hierarchy Process,AHP）和改进的加权灰色关联分析模型（Grey Relational Analysis,GRA）相结合的方法，综合2种方法的各自优势，以灰色关联分析为中心模型，以AHP模型为辅助模型，从造型、结构、体验3个方面综合考虑影响并条机的设计因素，通过AHP模型和Matlab辅助计算来确定并条机基准层中每一个因素各关联系数的权重向量，从而结合GRA计算出3个设计备选方案与最优方案的关联度，实现对各方案的优先排序。结论 通过实例分析表明，该方法可以评估并得出最佳的并条机设计方案，其评估过程也更具客观性和准确性，为制定后期其他设计方案提供量化分析参考。

Design and Evaluation of Drawing Frame Based on AHP and Weighted Grey Relational Analysis

In order to objectively evaluate the influence of qualitative index factors in the drawing frame on the drawing frame design and reduce subjective bias in the decision-making process of design scheme, an evaluation model was established to convert qualitative index into quantitative index of drawing frame and decide the best design scheme. By combining the analytic Hierarchy Process (AHP) with the improved Grey Relational Analysis (GRA), the respective advantages of the two methods were integrated. Taking the Grey Relational Analysis as the central model and the AHP model as the auxiliary model, the design factors affecting the drawing machine were comprehensively considered from the three aspects of modeling, structure and experience. The weight vector of each factor and each correlation coefficient in the reference layer of the drawing machine was determined through the AHP model and MATLAB auxiliary calculation. In this way, the correlation degree between the three design alternatives and the optimal scheme was calculated by combining GRA to realize the prioritization of each scheme. The application example shows that the method can be used to evaluate the best drawing frame design scheme, and the evaluation process is more objective and accurate, which provides quantitative analysis reference for other design schemes in later stage.
