摘要:

军用飞机机载系统承载着相互关联的多业务,如空战业务,而当前的机载系统可靠性评估方法仅由子系统可靠度简单组合得出系统可靠度,没有考虑子系统内部、子系统之间的相关关系,无法支持空战业务可靠性准确评估.为此,本文提出“机载系统空战业务可靠性”概念,设计实现多参数关联的机载系统空战业务可靠性评估方法:通过基于业务流程、基于中间件业务的分解方法分层分解业务,并提取各层参数,形成“业务可靠性参数-子业务可靠性参数-感官参数-中间件业务相关参数-具体服务步骤相关参数”的参数体系,并分析参数间关联关系,包括相关关系、依赖关系,建立多参数关联的业务可靠性评估模型,最后针对机载系统部署的空战业务,计算出空战业务可靠度.本文的评估方法有以下创新点和优势,第一,通过基于业务流程、基于中间件业务的分解方法分层分解业务,实现对业务的详细描述.第二,考虑参数间的相关关系、依赖关系,实现机载系统空战业务可靠性的精确评估.

Abstract:

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.

Key words: airborne system air combat application reliability, application decomposition, multi-parameter correlation, reliability evaluation
