在分析热加工过程缺陷主要因素的基础上,应用层次分析法,建立了热加工过程缺陷主要因素的层次结构模型和判断矩阵,计算出单层相对权重系数,进而完成了目标层的总排序权值计算,确定出影响热加工过程缺陷主要因素的综合排序权值。分析计算结果可为及时判断和处理产品在热加工过程出现的问题提供一定的参考。 Based on the analysis of the main factors of defects in hot working process, the hierarchical structure model and judgment matrix of the main factors of hot working process defects were established by using analytic hierarchy process, and the relative weight coefficients of single layer were calculated to complete the total ranking of target layer Value calculation, determine the main factors affecting the thermal processing defects comprehensive ranking weight. The results of the analysis and calculation can provide a reference for timely judgment and handling of the problems that occur in the hot working process.
