Application of TOPSIS Method Based on Entropy Weight in Nuclear Power Equipment Quality Evaluation

为更好地掌握核电站关键设备在客观性能上的质量状况,提出利用基于熵权的逼近理想解排序法(technique for order preference by similarity to ideal solution,TOPSIS)对核电设备质量进行评价。以核电厂压力容器堆芯筒节为例,验证了基于熵权的TOPSIS评价法可有效、科学、客观地评价设备的性能状况,最后剖析了该方法的特点和局限性。应用结果表明,该方法适用于评价核电站关键设备制造质量。

In order to better grasp the quality status of objective performance of key equipments in nuclear power plant, the technique for order preference by similarity to ideal solution （TOPSIS） was proposed based on entropy weight and used for the quality evaluation of nuclear power equipments. Taking the core barrel of the pressure vessel in nuclear power plant as example, it is verified that the TOPSIS method based on entropy weight can evaluate the performance status of equipments effectively, scientifically and objectively. Then the characteristics and limitations of the method were analyzed. The results show that the method is suitable for the manufacturing quality evaluation of key equipments in nuclear power plant.
