本文在新一代板材钢厂精准设计评价指标体系的基础上，以大型板材厂为对象，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名不同背景的专家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，总体上综合指标中经济投资水平指标的权重最大，而流程运行高效化和生态化水平指标的权重相对较低。专家的工作背景对指标的权重值有明显的影响，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。

In order to determine the weight of indicators in the former established accurate design assessment indicator system for new generation steel plants, an indicators weight analysis software is developed by using modified Analytic Hierarchy Process (AHP). An expert team consists of 71 experts with different work experience is employed to take advantage of the developed software to judge the indicators’ weights for a mass-production slab steel plant. The results of the obtained weights indicate that, in general the weight of economics/investment level is the highest and weights of process operation high-efficiency level and ecologization level are much lower among the four composite indicators. Indicator’s weight is greatly influenced by of experts’ experiences. 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 are raised with the promotion of expert’s titles and increase of working years.
