Research on Fire Safety Evaluation of Smoke Exhaust System Based on AHP and Fuzzy Comprehensive Evaluation Method

This paper establishes a fi re safety evaluation system of smoke extraction system with 16 three-level indexes from fi ve dimensions: smoke control partition, natural smoke extraction system, mechanical smoke extraction system, air supplement system and mechanical smoke extraction starting function. AHP is used to determine the index weight, and fuzzy comprehensive evaluation method is used to evaluate the risk of smoke exhaust system. The membership matrix of fi re safety of the system is obtained. According to the maximum membership principle, the overall fire safety level of the system is determined, which provides effective reference for the actual fi re supervision and inspection and system maintenance detection.
