离差偏好法在舰载直升机保障能力评估中的应用

Application of Deviation Preference Method in Ship-borne Helicopter Support Capability Evaluation

考虑到目前我国舰载直升机保障能力评估方面存在数据不完整、评估中需要考虑决策者偏好的问题,研究了基于离差偏好法的舰载直升机保障能力评估模型。在通过调研并考虑舰载直升机保障实际情况的基础上,构建了保障能力评估指标体系,并根据决策者的偏好建立了评估对象的互反判断矩阵;在保障能力评估中运用了离差偏好法,从对评估对象进行排序的角度对各个指标的权重进行了重新定义,建立了量值与偏好矩阵的偏差函数,通过实例分析表明该模型实用性较强,过程简单,适合现阶段舰载直升机保障能力评估问题的研究,具有一定的应用价值。

In view of the problems in ship-borne helicopter support capability evaluation,such as the data is incomplete,and the decision-maker＇s preference needs to be considered in evaluation,a model for evaluating the ship-borne helicopter support capability based on deviation preference method was studied. On the basis of investigation and the reality of ship-borne helicopter support,a support capability evaluation index system was constructed,and a reciprocal judgment matrix for evaluation subjects was established according to decision-maker＇s preference. A deviation preference method was adopted in support capability evaluation,the weight of each index was redefined from the perspective of sequencing the evaluation subjects,and a deviation function of the value with preference matrix was established. It＇s shown by case analysis that this model is more practical and simple in process,which is suitable for current study on the support capability evaluation problem of ship-borne helicopter and is of some application value.
