摘    要：在新一代钢厂精准设计评价指标体系的基础上,采用改进的层次分析法为核心算法开发了指标权重分析软件,邀请了71位不同背景的专家以大型板材钢厂为对象,采用该软件对各指标的权重进行了判定。对专家判定结果的分析表明,专家的工作背景对指标的权重值有明显的影响,指标的权重值在很大程度上决定于专家对该指标的了解程度。工作单位为企业、职称为正高级、工作时间20年以上、工作岗位为管理的专家得到的各指标权重值相差较小。流程运行高效化和生态化水平指标的权重随专家职称的提高以及工作时间的增加而增大。采用加权算术平均(WAMM)的方法,得到了经济投资水平、工艺设备水平、流程运行高效化和生态化水平4大类指标的最终权重值分别为0.285、0.249、0.240和0.226。

Abstract: In order to determine the weight of indicators in the former established accurate-design assessment indicator system for new generation steel plants,the indicator weight analysis software was developed by using modified Analytic Hierarchy Process(AHP).An expert team consisted of 71 experts with different work experience was employed to take advantage of the developed software to judge the indicators′ weights for a mass-production slab steel plant.The obtained weights indicate that indicator′s weight is greatly influenced by of experts′ experiences.The weight of an indicator depends largely on the expert′s familiarity to this indicator.The differences of weights between the four composite indicators are relatively smaller when the weights are obtained by the experts with experiences of working in steel plants,having a senior title,working over 20 years,or working on management position.The weights of process operation high-efficiency level and ecologization level rise with the promotion of expert′s titles and increase of working years.Using Weighted Arithmetic Mean Method(WAMM),the weight of economics/investment level,procedure equipment level,process operation high-efficiency level,and ecologization level are determined as 0.285,0.249,0.240 and 0.226 respectively.
