## 5 Example Analysis
### Calculate the Weight of Differentiated Service Communication Requirement Indexes  
Based on the FAHP method, referring to Table 1 and Formulas (1)-(8), experts scored to obtain the fuzzy judgment matrix. After checking for consistency, the subjective weights of communication indexes for the four services with differentiated communication requirements are calculated, with the results shown in Table 3.  
Based on the improved CRITIC method, utilizing Table 2 and Formulas (9)-(19), the original evaluation matrix is normalized. Subsequently, the standard deviation, correlation coefficient, and entropy value are calculated as the basis for assessing the conflict, volatility, and amount of information of the indexes, respectively. Finally, considering all three factors comprehensively, objective weights are assigned to each index. The objective weight vector is \(\epsilon\) = (0.2356, 0.1308, 0.1336, 0.1421, 0.1855, 0.1724). According to Formula (20), the objective weights are combined with the subjective weights of the communication indexes for the four services to obtain the combined weights, as shown in Table 4.  
According to Table 4, the top three indexes for combined weight ranking in the precision load control service are security, latency, and bit error rate. For the electricity information collection service, the top three indexes for combined weight ranking are bit error rate, cost, and transmission distance. In the load management terminal monitoring service, the top three indexes for combined weight ranking are bandwidth, cost, and security. For the power market transaction service, the top three indexes for combined weight ranking are security, transmission distance, and latency. The precise load control service requires that communication content is protected from unauthorized access, tampering, or theft, ensuring that load control commands are transmitted swiftly and accurately. Consequently, the security, latency, and bit error rate \begin{table}

As a basic service, the electricity information collection service necessitates the accuracy of collected information. The deployment of large-scale collection equipment increases the significance of bit error rate, transmission distance, and cost in the communication technology supporting this service. The load management terminal monitoring service involves transmitting large volumes of sensitive video and image information, imposing higher requirements on communication bandwidth and security.
