# Knowledge-Graph-Based Integrated Line Loss Evaluation Management System
## 5 Construction of a Mapping of Management Cases for Comprehensive Line Loss Evaluation
### Comparative Analysis
This suggests the presence of an effective line loss management model. For a period of two years between 2014 and 2016, four municipalities, BS, HZ, QZ and WZ, were categorized as Category C line loss management companies. These areas are subject to national policy support and attention, particularly in regard to ethnic minority issues. They may also possess specific geopolitical advantages and challenges, notably in the context of poverty alleviation, regional development, and ethnic minority policies. Amongst these, QZ and WZ were initially classified as Category A for their line loss management in 2014. However, they were subsequently reclassified as Category C for two consecutive years from 2015 to 2016. Consequently, they may encounter similar economic development challenges, including the necessity to enhance infrastructure development, facilitate industrial upgrading, and improve the investment environment, in addition to other pertinent issues. The remaining provinces and cities were classified as category B from 2014 to 2016, including LZ, FCG, GG, LB, and CZ. The findings of the study indicate a notable geographical variation in line loss management capacity within the Guangxi region. In terms of the overall ranking, the line loss management capability is stronger in tourist coastal areas and economically developed areas, weaker in ethnic minority and economically weaker areas, and the rest of the regions fall into the middle category. In order to ascertain the reasons for the discrepancies in the overall ranking, the results of the ranking of the sub-items pertaining to line loss management ability were classified and subjected to analysis. The management loss reduction capability, which accounts for the largest number of indicators, is taken as an example here. The classification table of management loss reduction capability is shown in Table 7.  
The municipalities of LB, YL, GG, and CZ collectively demonstrate a robust capacity in the domain of line loss management, exhibiting consistently high levels across the three-year period from 2005 to 2007. Consequently, they are classified as A. In contrast, the municipality of BH exhibited a B classification in 2014 but subsequently demonstrated superior performance, achieving an A classification from 2015 to 2016. Consequently, it is also classified as A. BS was classified as A from 2014 to 2015 and is therefore also classified as A. QZ The municipal bureau's line loss management input capacity is insufficient, ranking 7 th in 2014, and has subsequently declined, from 2015 to 2016, to 13 th, belonging to category \begin{table}
\begin{tabular}{c c c c} \hline \hline  & **Year 2014** & **Year 2015** & **Year 2016** \\ \hline \multirow{2}{*}{Category A} & LB(1)YL(2)GG(3) & BS(1)CZ(2)YL(3) & YL(1)CZ(2)LB(3) \\  & CZ(4)BS(5)FCG(6) & LB(4)BH(5)GG(6) & HZ(4)BH(5)GG(6) \\ \hline \multirow{2}{*}{Category B} & QZ(7)GL(8) & HEC(7)FCG(8) & GL(7)NN(8) \\  & WZ(9)HEC(10) & QZ(9)WZ(10) & LZ(9)WZ(10) \\ \hline \multirow{2}{*}{Category C} & LZ(11)HZ(12) & HZ(11)NN(12) & HEC(11)FCG(12) \\  & NN(13)BH(14) & LZ(13)GL(14) & QZ(13)BS(14) \\ \hline \hline \end{tabular}

Table 7: Overall ranking breakdown of loss reduction capabilities in line loss management category, 2014-2016. B. QZ should continue to increase investment to enhance the local management technology input capacity. GL management input capacity is also insufficient, belonging to category B, but the ranking has risen. NN, HZ, and LZ are three municipal bureaus with weaker management capabilities in the area of line loss. It may be the case that these bureaus suffer from weaker management capacity, which may be related to their management planning and system. In order to enhance the effectiveness of line loss management, it would be beneficial to implement a more scientific and reasonable comprehensive evaluation system.
