Research on Disaster Risk of Transmission Line Based on AHP-Entropy-TOPSIS Theory
For the purpose of transmission line disaster risk assessment,a transmission line disaster risk assessment method is proposed.The improved attribute reduction algorithm is used to reduce the selected indicators.The subjective and objective comprehensive evaluation method combining analytic hierarchy process(AHP)and entroy weight(EW)method is used to cal-culate the combination weight of the reduced indicators.Technique for order preference by similarity to an ideal soluation(TOPSIS)model is used to evaluate the disaster risk of transmission line as the final evaluation result.Take three transmission lines in actual operation as an example.The results show that the evaluation method scientific considers various factors affect-ing the transmission line,and comprehensively compares and analyzes the importance of selecting indicators,which makes the evaluation results more accurate and can be used as a method to evaluate the disaster risk of transmission line.
