灰色层次分析法在航空工业企业事故中的分析运用

航空工业常使用高精度、高价值的关键仪器、设备、设施,各种型号飞机试验、试飞频繁。机械伤害、高处坠落、冲压设备伤手等事故时有发生。分析航空企业事故致因主要为事故预防措施不到位,生产工艺设备安全性不高,职业病预防及管理不到位。利用数学建模的思路,引入灰色层次分析法(GAHP),以航空某企业为例,将评估对象安全状况分为指标层、准层次、目标层,逐级计算灰数,确定所属灰类,得出航空某企业的安全综合评估结果。评估结果显示,GAHP法能够客观反映航空企业安全状况,值得在航空企业安全生产事故风险评估中推广使用。

Application of GAHP to the Safety Assessment of Aviation Enterprises

Since high-precision,high-value critical apparatus,equipment and facilities are often used in aviation industry and various models of aircraft are tested frequently,mechanical injuries,falls and hand injuries by stamping equipment often occur.Based on the objective analysis of aviation safety accidents,it is found that major factors causing aviation accidents are poor prevention measures,low security of production equipment and weak management on occupational diseases.By using the idea of mathematical modeling and Grey Analytic Hierarch Process(GAHP) method,an evaluation method for aviation enterprise is established.With an aviation enterprise as an example,its safety situation is divided into index layer,quasi-level and target level.By calculating the gray number and gray level,the comprehensive assessment result for this aviation company's safety situation is achieved.Assessment shows that the gray-level analysis can objectively reflect the safety situation of aviation enterprises,and is worth using and promoting in the aviation safety risk assessment.
