基于综合集成赋权法的飞行机务保障能力评估指标权重确定

为提高指标权重的精确性,避免单一赋权方法在赋权中存在的局限性,采用基于综合集成赋权法,将主观赋权法(德尔菲法)和客观赋权法(熵值法)进行综合.在考虑主客观赋权法的优缺点及评估对象特点的前提下,利用德尔菲法和熵值法分别得到2个权重向量,采用基于最小二乘法和相对熵的综合集成赋权法给出综合权重.结果表明:该方法可在一定程度上提高指标权重的精确性,为评估指标权重的可靠性和准确性打下了基础.

Determining the Weights of Evaluation Index in Flight Line Maintenance Support Ability Based on Combination Weight Method

The subjective weight method (Delphi method) and the objective weight method (the entropy) comprehensive are combined through the integrated weight method to improve the accuracy of the index weight, and avoid the limit of single weight method. Two weight vectors were obtained, on the premise that the advantages and disadvantages of subjective and objective weight methods are considered and the features of the object are evaluated. After that the comprehensive weight are given based on least square method and integrated weight method of relative entropy. The result shows that the method can improve the accuracy of the index weight to a certain extent, and lay a foundation for the reliability and accuracy of the evaluation index weight.
