Abstract: A quantitative risk assessment method for power communication networks based on fuzzy analytic hierarchy process (FAHP) has been proposed. Firstly, a risk indicator system is constructed using key performance indicators such as network reliability, security, latency, and bandwidth in power communication networks. Based on the risk indicator system, a fuzzy hierarchical structure model was established. The risk assessment results are transformed into specific quantitative values through quantitative analysis, in order to achieve quantitative evaluation of power communication network risks. After introducing this method, the frequency of these abnormal situations is effectively reduced and stabilised at four times or less per month, thereby enhancing the stability of the network; the accuracy of risk assessment within three months is consistently above 90%, with the highest reaching 97%; at 100 iterations, the risk assessment time of our method is only 7 seconds.

Keywords: fuzzy hierarchical analysis; electric power communication network; quantitative risk assessment; construction of risk index system; multi-level structure; fuzzy evaluation.
