中文摘要：

电炉冶炼作业管理大都采用定性分析和主观判断的方法。将数据包络分析DEA引入电炉冶炼作业的分析评价，给出了适用的定量化分析方法。在输入资源及成本动因，输出作业量的基础上，DEA方法可以评价作业消耗资源的效率，并为作业改进提供有价值的信息。为了使分析可靠，通过对投入产出指标进行组合进行了敏感度分析。论文用上述模型对某钢铁企业的电炉冶炼作业进行分析，结果反映该方法客观、准确，具有较强的实用价值。

英文摘要：

In the application of Activity-based Management in Electric Arc Furnace activity, the subjective judgment and analysis methods are often used. The paper gives a quantization method of Electric Arc Furnace activity analysis and evalua- tion using data envelopment analysis （DEA）. Based on resources input and activity quantity output, the DEA model can evaluate the resources utilization efficiency of activity. By the input-output combination, the sensitivity analysis is done. At last, the paper demonstrates the application in electric arc furnace activity of a steel enterprise. The result implies good objectivity accuracy and practicability of the activity analysis and valuation method based on DEA.
