High-rise building electrical fire risk two-stage evaluation method based on interval TOPSIS method

Abstract

The invention provides a high-rise building electrical fire risk two-stage assessment method based on an interval TOPSIS method, and the method comprises the steps: 1, determining an electrical fire risk factor main index and sub-indexes from the electrical fire risk assessment through combining the electrical fire features of a high-rise building, and constructing a building electrical fire risk assessment index system; step 2, calculating weight coefficients of the main index and the sub-index of the electrical fire risk factor by adopting an interval analytic hierarchy process; and step 3, according to the calculated weight coefficients of the main index and the sub-index of the electrical fire risk factor, identifying the electrical fire risk factor of the high-rise building by combining an interval TOPSIS method, quantitatively representing the importance degree of each index, and performing quantitative analysis on the constructed evaluation index system. According to the risk assessment method provided by the invention, fire risk factors can be effectively identified, electrical fire prevention measures can be timely formulated, and the timeliness and reliability of high-rise building electrical fire protection are improved.

Description

Technical field [0001] The present invention relates to the field of high-rise building electrical fire risk assessment, and is specifically a two-level assessment method for high-rise building electrical fire risk based on interval TOPSIS method. Background technique [0002] In recent years, urban high-rise buildings have been increasing. In high-rise building power machine rooms, cable wells, pipe wells, non-standard, electrical equipment capacity load exceeds standard or installation, and some fire protection power supply is not implemented, leading to frequent high-rise buildings The people's personal and property safety are greatly threatened. Therefore, it is urgent to focus on high-rise building electrical fire safety comprehensive management, resolutely prevent and curb high-rise buildings. To this end, the fire safety mechanism should effectively assess the risk of electrical fire and take the necessary precautions. Inventive content [0003] In view of this, the prese...

AI Technical Summary

Problems solved by technology

In high-rise building electrical machine rooms, cable wells, and pipeline wells, the electrical lines are randomly pulled or connected indiscriminately or the laying does not meet the specifications, the capacity load of electrical equipment exceeds the standard or the installation is not standardized, and some safety protection measures for fire-fighting power supplies have not been implemented, resulting in frequent electrical fires in high-rise buildings. , people's personal and property safety are greatly threatened
