基于组合赋权和云模型的工业通信质量评估

Industrial communication quality evaluation based on combination weighting and cloud model

针对工业通信网络缺少通信质量评估方法的现状,提出基于组合赋权和云模型的工业通信质量评估方法。结合工业通信网络的背景,选取8个工业通信指标建立工业通信网络评价体系。运用最优传递矩阵改进的层次分析法和变异系数法分别计算指标的主观权重和客观权重,基于离差最大化思想进行组合赋权,避免单一确权方法计算指标权重的片面性。结合云模型将指标权重量化为评价等级,直观地反映评价结果。仿真结果表明,该方法能够有效地评价工业通信质量。

In the view of the lack of communication quality evaluation methods in industrial communication networks,an industrial communication quality evaluation system with eight indicators was established combined with the background of industrial communication networks.The improved analytic hierarchy process and the coefficient of variation method were used to calculate the subjective and objective weights of indicators respectively.Maximum deviation method was used to combine these two kinds of weights,which avoided the one-sidedness of single method.Indicator weights were converted into evaluation grades with cloud model to show the comprehensive evaluation results intuitively.The simulation results indicate that the proposed method can effectively evaluate the communication quality of industrial communication networks.
