摘　　要：针对当前民机研发过程对系统工程与过程方法理解和运用仍然存在疑虑的问题,本文选择以面向对象的方式观察和分析了项目实践中的航电系统工程及其过程方法,利用系统建模语言建立了一组系统工程与过程的对象模型,以可视化方式展示了抽象层面上系统工程的结构和行为以及它们之间的联系。清晰的模型有利于人们更好地理解和交流,本文重点介绍了如何把经验中的过程方法用对象模型进行表达的方法。文中模型包括系统工程的用例、生命周期、过程规范、系统工程与项目以及系统工程类的操作等。模型是对现实的简化和抽象,对系统工程与过程的本身建模是一次尝试,旨在为民机航电系统产品的开发与体系建设提供理论和实践方面的指导。In response to the current doubts about the understanding and application of system engineering and pro-cess approach in the development process of civil aircraft,the practical application of avionics system engineering and process approach is observed,analyzed,and summarized in an object-oriented view.Using SysML(System Modeling Language),a set of object models of system engineering and processes is created to visualize the structure and behavior of system engineering at an abstract level,as well as the relationships between them.An object model is beneficial for people to better understand and communicate.Focus is put on how to express process approach from program expe-rience using object models.The models introduced include use cases,system engineering lifecycle,process specifica-tions,system engineering and project classes,as well as operations in system engineering.A model is a simplification and abstraction of reality,and it is an attempt to model the system engineering and processes itself,aiming to provide theoretical and practical guidance for the development of civil aircraft avionics system products and the processes of the system construction.
