Firstly,based on the welding process framework,the comprehensive evalu-ation index system of welding process resources and enviro-nment attributes is constructed. Secondly,the subjective/obj-ective weight quantization method of evaluation index based on AHP-entropy method is proposed,and the final evaluation value and evaluation interval are calculated by TOPSIS method.Finally,the effectiveness and practicability of the above methods are verified through the case analysis of the evaluation of the process resources and environment properties of a workpiece for manual arc welding. 焊接工艺 AHP-熵值法 评价指标模型 TOPSIS法 综合评价 welding technology AHP-entropy method evaluation index model TOPSIS method compreh-ensive evaluation TG44 国家重点研发计划项目“焊接工艺资源环境负荷数据采集与环境影响评价”(2018YFB2002103) 2022-03-08 1 51
