机载电子系统开发过程本地化方法

摘要

Due to the complexity of the airborne system,it is difficult to implement exhaustive testing.To assure the system airworthiness,relevant sets of standards have been issued by SAE and RTCA,defining the development process.However,the standards are established in the way of "what" rather than "how".Consequently,it requires the users to not only understand,but also formulate a localized procedure in order to apply these standards effectively.The airborne electronic system is a typical complex system,thus a localized procedure is needed for establishing the system airworthiness standard.This paper proposes a method to construct customized development process for the airborne electronic systems.The method considers both management requirements and engineering approach to target an integrated,flexible and efficient process.%由于复杂机载系统通常情况下无法进行穷举测试,为了保证其满足适航要求,SAE,RTCA等国际组织发布了一系列标准定义相关的开发过程要求,以弥补测试的不足.然而上述标准是基于目标形式定义的,不提供具体的工程实施方法,标准使用者需要在充分理解标准的基础上,根据企业的产品特点及管理模式,形成符合标准要求的本地化开发过程才能够有效地应用标准.光电及其控制系统等机载电子系统是典型的复杂机载系统,为满足民机适航要求,需要为这些系统建立满足适航标准要求的本地化开发过程.介绍了一种建立本地化开发过程的方法,该方法将管理要求和工程元素有机结合,形成完整、灵活、高效的本地化开发过程.
