多参数关联的机载系统空战业务可靠性评估方法

The airborne system of military aircraft carries multiple applications that are interrelated with each other, such as air combat applications.But the current airborne system reliability evaluation methods evaluate system reliability by simply combining the subsystem reliability. The methods don't consider correlation of the internal and between subsystems, which unable to support the accurate evaluation of air combat application reliability. Therefore, this paper proposed the concept of airborne system air combat application reliability and the airborne system air combat application reliability evaluation method based on multi-parameter correlation. The application was decomposed to layers by application process and middleware application decomposition, then the parameters of each layer was extracted to form parameters system including application reliability parameters, sub-application reliability parameters, sensory parameters, middleware application related parameters, and specific service process related parameters. The application reliability evaluation model based on multi-parameters correlation was proposed by analyzing relationships between parameters which includes correlation and dependency. Finally, for airborne system air combat application, the reliability of air combat application is calculated. The innovations and advantages of proposed evaluation method are as follows. Firstly, the application was decomposed to layers by regular application process and middleware application decomposition, which could realize detailed description of application. Secondly, the airborne system air combat application reliability was accurately evaluated by considering correlation and dependency between parameters.
