# Knowledge-Graph-Based Integrated Line Loss Evaluation Management System
## 5 Construction of a Mapping of Management Cases for Comprehensive Line Loss Evaluation
### Comparative Analysis  
The evaluation results for line loss management capability from 2014 to 2016 are classified into three categories. Those ranked in the top six are classified as Category A, indicating a high level of line loss reduction management capability. Those ranked in the bottom four are classified as Category C, indicating a low level of line loss management capability. The remaining results are classified as Category B, indicating a mid-range level of line loss management capability.For a detailed breakdown of the classification, please refer to Table 6.  
In the period spanning 2014 to 2016, both BH and GL municipalities were classified as Class A line loss management companies. Similarly, the three municipal corporations of NN, \begin{table}

Table 5: Topsis composite score and ranking results for each secondary indicator score table for all years. HEC, and YL were classified as Class A line loss management companies in two of the years between 2014 and 2016. The two cities of BH and GL, which are popular tourist destinations, have a high level of economic development and relatively well-developed infrastructure and advanced power management technology, which contributes to a reduction in line loss. The two cities benefit from the government's policy support and regional development strategy, which may include the priority of grid construction and upgrading, as well as access to technical and financial support. It is plausible that the three urban areas of NN, HEC, and YL have undertaken grid construction and technological upgrading over the past two years. This may have led to an improvement in the transmission efficiency of the grid and a reduction in line loss, particularly for the two companies NN and YL, whose overall index rank and scores have exhibited a consistent upward trajectory.
