基于改进灰色关联的装备维修保障能力评估模型

Evaluation Model of Equipment Maintenance Support Capability Based on Improved Grey Relation

在分析研究装备维修保障能力评估中不确定性问题的基础上,提出了一种基于改进灰色关联的装备维修保障能力评估模型。该模型采用灰色关联分析计算出各装备维修保障系统与目标值的关联程度,利用有偏好熵权法确定指标权重,并结合关联系数和指标权重获得灰色关联度,可得到各维修保障系统的优劣顺序。文章通过实例应用,验证了该方法的可行性和实效性。

On the basis of analyzing the uncertainty problems about equipment maintenance support capability evaluation,this paperproposes an evaluation model of equipment maintenance support capability based on improved grey relation.The model uses grey relationanalysis to calculate the relation degree between each equipment maintenance support system and target value,and uses preference entropyweight to determine the index weight.The quality of maintenance support system can be obtained through combining the grey relationquotient with index weight.The application example shows that this method is simple and strongly effective.
