IP网络运行质量模糊综合评估方法研究

摘要

针对现有网络运行质量评估方法不能同时反映指标重要性和决策者偏好性的问题,提出了采用WOWA算子的网络运行质量模糊综合评估方法.WOWA算子在合成计算时结合了反映指标自身重要性的权重和反映决策者主观偏好的权重,充分考虑了指标本身的重要性和决策者偏好的重要性.实例表明,与普通模糊综合评估方法相比,该方法不仅能够得出正确评估结果,而且能够反映决策者的偏好使得评估更加灵活和适应性更强.%The fuzzy comprehensive evaluation method based on WOWA operator is presented for solving the problem that the current network operational quality method can't simultaneously reflect the metrics'importance and decision-maker's preference. The WOWA operator combines the weights which reflecte the importance of metric and the weights which reflecte the importance of the decision-maker's preference, so that it completely consideres the importance of the metrics and decision-maker's preference in the aggregation process.The case study shows that the method in comparison with the normal fuzzy evaluation method can not only achieve the correct evaluation results, but also reflect the decision-makers' preference.
