Airline Safety System Risk Assessment based on Evidence Theory

Risk assessment to airline company safety system is an effective measure that insures safety running of an airline company.In the assessment,there are lots of uncertain factors affecting the safety of an airline company.For solving the problem of uncertainty in airline company's safety system risk assessment,it brings evidence theory to the assessment.In this paper,an indicator system of airline company safety system risk assessment has been established.An arithmetic and a model of airline company safety system risk assessment based on evidence theory have also been developed.Finally,an example shows that the method can effectively solve the problem of uncertainty in airline company safety system risk assessment.
