基于物元可拓模型的民航企业SMS有效性评价研究

Study on the Effectiveness Evaluation of SMS for Civil Aviation Enterprise Based on Matter Element Extension Model

为量化评价民航企业SMS有效性,持续改进民航SMS,通过分析民航企业SMS有效性的内涵和表征,将符合性、目标性、适宜性、充分性和文化性5个指标作为民航企业SMS有效性评价的一级指标,并进一步划分为20项二级指标。从系统工程的角度出发,结合可拓理论、层次分析法的基本原理,确定其指标体系、指标经典域和节域,确定了待评物元及关联度,建立了SMS有效性物元可拓评价模型,并运用该模型对A航空公司进行实例验证,得出A航空公司SMS评价等级为Ⅱ级。评价结果表明,该模型可以反映民航企业SMS有效性评价水平,可为提升SMS有效性提供理论基础。

In order to evaluate the effectiveness of safety management system for civil aviation enterprises,the civil aviation safety management system is improved persistently.Based on the analysis of the connotation and representation of the effectiveness of SMS in civil aviation enterprises,five indicators of compliance,including goal,suitability,sufficiency and culture,are taken as the first level indicators of the effectiveness evaluation of SMS in civil aviation enterprises,and 20 as second level indicators.From the view of the system engineering,combined with the basic principles of matter element extension theory and Analytic Hierarchy Process(AHP),the index system,the index classical domain and the joint domain are determined and the evaluation model of the validity of security management system is established.By the model of example verification for A Airline,it is concluded that the SMS evaluation grade of A Airline is evaluated as levelⅡ.The results show that the model can reflect the whole level of the effectiveness evaluation of SMS for civil aviation enterprises,which can provide theoretical basis for the construction of enhancing SMS effectiveness evaluation.
