多层次灰色评估法在装备设计定型过程评估中的应用

Application of Multilayer Grey Evaluation Method in Process Evaluation of Equipment Approval

为减少人为因素对装备设计定型过程评估带来的偏差,建立一个多层次灰色评估模型。该模型将层次分析法(analytic hierarchy process,AHP)法与灰色关联分析(gray relation analysis,GRA)法有机结合,由AHP法构建层次结构关系图,确定各层中元素的相对权重,然后应用GRA法计算获取指标与目标指标的关联度,确定装备满足设计定型的水平。评估结果表明:该模型解决了评估指标难以准确量化和统计的问题,提高了评估的科学性和精确性,为装备设计定型工作提供了一种新的思路和新的方法。

In order to reduce the deviation of equipment approval evaluation process by the human factors, designed a multilayer grey evaluation model, which combined analytic hierarchy process （AHP） with grey relation analysis （GRA）. Hierarchy graph is designed by AHP, and relative weight of element in every layer is defined, then the degree of association between obtained indicator and target indicator is calculated by GRA, in order to make sure the level of equipment approval This model solved the problem of evaluation index hard to quantify and statistics, improve the scientificity and accuracy of the evaluation, which provided a new method for equipment design and approval work.
