Two-Level Assessment Method for Electrical Fire Risk of High Rise Buildings Based on Interval TOPSIS Method
The electrical fire risk of high-rise buildings remains high, which has threatened people’s life and property safety for a long time. Therefore, accurately evaluating the electrical fire risk and identifying the risk factors can effectively formulate the electrical fire prevention measures. Therefore, this paper proposed a two-level assessment method of electrical fire risk of high-rise buildings based on interval TOPSIS method. Firstly, the electrical fire data and expert evaluation opinions are queried, and the improved Delphi method is used to obtain the two-level index framework of electrical fire risk assessment. Then the interval analytic hierarchy process is used to determine the weight coefficient of electrical fire risk index of high-rise buildings. Finally, the risk index factors are sorted in combination with interval TOPSIS method. After verification, it is found that the sequence of electrical fire risk factors of high-rise buildings is the chain reaction of inflammables and explosives (accounting for 27.9%), the fire caused by electrical lines (accounting for 22.07%) and the fire caused by electrical equipment (accounting for 20.89%), in which the overload risk factor accounts for the largest proportion in the sub-indicators.
