A dynamic evaluation method based on broadband grid cell quality
Based on subjective KQI data and objective network KPI data that affect customer perception,a multi-level and multi-dimensional dynamic evaluation system based on grid cell users is established.Through such indicator factors as impact degree basis factor,sensitivity factor,and continuous deterioration factor,the evaluation indicators are dynamically adjusted to distinguish between scenarios and user portraits.The entropy method is applied to calculate the weight of indicators in each dimension,and a variable weight function is introduced to dynamically adjust the initial weight.Finally,the TOPSIS comprehensive evaluation method is used,taking into account the different impact degrees of each dimension on the overall evaluation,and the comprehensive evaluation score of the grid cell is obtained after normalization.The statistical data validation of the actual use effect shows that the dynamic evaluation al-gorithm can better reflect the actual use perception of grid cell users.
