摘要

针对量大面广的焊接工艺过程原材料、能源消耗大

环境污染严重等问题

提出了一种基于组合权证与TOPSIS的焊接工艺资源环境属性评价方法。首先

基于焊接工艺流程框架

构建了焊接工艺资源环境属性综合评价指标体系;其次

提出了基于AHP-熵值法的评价指标主观/客观权重量化方法

利用TOPSIS法计算最终评价值与评价区间;最后

通过以某工件焊条电弧焊工艺资源环境属性评价案例分析

对上述方法的有效性和实用性进行了验证。

Abstract

This paper proposes a welding process resource and environment attribute evaluation method based on com-bination certificate and TOPSIS

aiming at the problems such as large amount of welding process raw materials

high energy consumption and serious environmental pollution. 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.
