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。
Aviation industry often use high-precision, high-value key instruments, equipment, facilities, various types of aircraft tests, frequent flyovers. Mechanical injury, falling from height, punching equipment injuries and other accidents have occurred. Analysis of aviation accidents is mainly due to accident prevention measures are not in place, production process and equipment safety is not high, occupational disease prevention and management are not in place. Using the idea of mathematical modeling, this paper introduces the Gray Analytic Hierarchy Process (GAHP), taking an aviation enterprise as an example, divides the safety status of the evaluation objects into indicator level, quasi-level and target level, calculates the gray level by level, Draw a safety assessment of a business aviation results. The assessment results show that the GAHP method can objectively reflect the safety status of aviation enterprises and is worthy of promotion and application in the risk assessment of production safety accidents in aviation enterprises.
