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 understand the objective quality of key equipment of nuclear power plant, this paper proposes to evaluate the quality of nuclear power equipment by using TOPSIS based on entropy weight. Taking nuclear reactor pressure vessel core barrel section as an example, it is verified that the TOPSIS evaluation method based on entropy weight can evaluate the performance of the equipment effectively, scientifically and objectively. Finally, the characteristics and limitations of the method are analyzed. The application results show that this method is suitable for evaluating the manufacturing quality of key equipment in nuclear power plants.
