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.
