Analysis on Causative Factors of Aviation Maintenance Errors Based on AHP and Entropy Weight Method
In order to accurately identify the important causes of aviation maintenance errors and improve the pertinence of preventive measures,an evaluation index system of cause of aviation maintenance error is set up based on SHEL model com-posed of personnel,hardware,software and environment.Taking the aviation maintenance of a naval aviation unit as an ex-ample,the importance of each index is analyzed by AHP and entropy weight method,and combining the results of both ana-lyses,the preventive measures are proposed.The analysis results showed that the main causative factors obtained by AHP are interpersonal and communicative competence,information platform,physical/psychological quality,workload and personnel training.The main causative factors obtained by entropy weight method are aircraft structure,personnel training,interpersonal and communicative ability,maintenance equipment and equipment,and knowledge and skills.It is suggested that the army can strengthen the process records by means of information technology to ensure the complete handover of work and other measures.
