基于风险矩阵分析的新疆吉木萨尔地区某煤化工企业模糊综合风险评价

Risk assessment by fuzzy mathematics of a coal chemical enterprise in Jimsar of Xin Jiang:based on risk matrix analysis method

目的综合评价新疆吉木萨尔地区某煤化工企业职业危害风险水平。方法采用风险矩阵分析法评估企业化学有害因素风险水平,进而根据改进的模糊层次分析法构造比较矩阵,计算权重。最后通过模糊综合评价法综合评判企业化学有害因素、物理有害因素以及粉尘的危害风险。结果化学有害因素风险排序为氨(3.14)、二氧化氮(2.93)、二氧化硫(2.64)、硫化氢(2.62)、一氧化碳(2.62)。从各因素检测结果隶属度矩阵来看,各化学有害因素隶属于可忽略风险等级的程度较高;噪声隶属于中等风险的等级较高,达到33.3%;粉尘相对于高风险的隶属度达到41.7%。该企业化学有害因素、粉尘、噪声模糊综合评价等级为Ⅰ级(42.0%),为可忽略风险。结论该煤化工企业职业危害风险水平较低,属于可忽略风险水平;将风险矩阵分析法、改进的模糊层次分析法、模糊综合评价法综合应用于企业职业危害风险评价,有利于得到客观科学的评价结果。

[Objective] To evaluate the occupational hazards risk level of a coal chemical enterprise in Jimsar of XinJiang. [ Methods ] The risk matrix analysis method was adopted to appraise risk level of chemical hazards in the enterprise, and the modified fuzzy analytic hierarchy progress was used to establish matrix and calculate weight, then synthetically evaluate the risk level of chemical hazard factors, physical harmful factors and dust by fuzzy mathematics. EResultsl The risk levels of chemical hazard factors were ammonia（ 3.14 ）, nitrogen dioxide（2.93 ）, sulfur dioxide （2.64）, hydrogen sulfide（2.62）, and carbon monoxide （2.62）. In terms of membership matrix, the chemical hazard factors were mostly negligible risk level, the noise mainly belonged to medium risk level by 33.3% and the dust mainly belonged to high risk level by 41.7%. By the comprehensive evaluation, the risk level of chemical hazard factors, dust and noise belonged to grade I （42.0%）, which was the negligible risk.[Conclusion] The occupational risk level of this coal chemical enterprise is low, which belongs to negligible risk level, h is beneficial to get objective and scientific results by applying the risk matrix analysis, the modified fuzzy analytic hierarchy progress and comprehensive assessment based on fuzzy mathematics to evaluate the risk level of occupational harm in enterprises.
