Research on Airline Risk Influencing Factors Based on ISM and AHP-Entropy
For the study of airline risk factors,ISM-AHP-Entropy comprehensive evaluation method is in-troduced to evaluate the risk factors.Firstly,the risk factor index system is constructed from the collection of literature,actual research and expert questionnaires.Secondly,the factor indexes are divided into sur-face and deep causative factors by using analytic structural model(ISM)to construct the structural mod-el;after that,according to the results of questionnaires,the comprehensive weights are derived by using AHP-Entropy,and the results show that the human factors and management factors have the most signifi-cant influence on the risk;the AHP-Entropy synthesis method is further used to calculate the weights of surface and deep causative factors respectively and analyze the results.Further,the AHP-Entropy synthe-sis method is used to calculate the weights of surface and deep causal factors and analyze them respective-ly,and the results show that among the surface causal factors,the level of crew resource management and the emergency response capability of dispatchers have the most significant influence,while among the deep causal factors,the formulation of safety regulations and guidelines and the training and implementa-tion of emergency management have the most significant influence;lastly,we put forward a proposal to re-duce risk and improve safety awareness and level for the airlines from multiple realistic perspectives,com-bining with the concept of CBTA.Finally,from a number of practical perspectives and in combination with the CBTA concept,we put forward a number of suggestions for airlines to reduce risk and improve safety awareness and level,which can be adopted by airlines.
