基于可变模糊集理论的实验室安全综合评价

Comprehensive Evaluation Method of Laboratory Safety based on Variable Fuzzy Set Theory

针对现有模糊层次分析法存在的隶属度确定过于绝对的问题,本文将可变模糊集理论引入到实验室的安全综合评价中,建立一种基于可变模糊集理论的实验室安全综合评级模型,并以河海大学某实验室为例进行分析,从不同角度对实验室安全进行综合分析,得到不同层面的实验室安全评价等级以及实验室综合安全评价等级。结果表明该实验室安全综合等级为良好,且在人员、设备、环境三个方面表现较好,在管理层面存在一定缺陷。仿真结果表明:该模型具有操作简单、可从不同角度进行分层评价的特点,能在对实验室进行综合安全评价的同时,进行多角度评价,便于分析实验室安全的薄弱环节,进而进行针对性改进。

Aiming at the problem that the membership degree determination of the existing fuzzy analytic hierarchy process is too absolute,this paper introduces the variable fuzzy set theory into the comprehensive evaluation of laboratory safety,and establishes a comprehensive laboratory safety rating model based on the variable fuzzy set theory.This paper takes a laboratory of Hohai University as an example to analyze the laboratory safety from different angles,and obtain different levels of laboratory safety evaluation grades and comprehensive laboratory safety evaluation grades.The results show that the comprehensive safety level of the laboratory is good,and it performs well in terms of personnel,equipment,and environment,and has certain defects in the management level.The simulation results show that the model has the characteristics of simple operation and hierarchical evaluation from different angles.It can conduct comprehensive safety evaluation of laboratories and conduct multi-angle evaluations at the same time,and then make targeted improvements.
