基于原型仿真的航空电子系统螺旋式开发方法

针对未来航空电子系统面临的挑战和航空电子系统设计的特点,提出基于原型仿真的航空电子系统螺旋式开发方法,克服了瀑布式系统开发方法在航空电子系统开发中的缺陷。该方法强调概念和需求的验证,克服因系统设计早期发生错误而引起系统研制后期更大的更改;强调图形化设计和原型仿真,克服错误的需求理解导致错误设计;强调系统建模,一方面可以在模型上进行各种验证和试验工作,另一方面可以重复迭代和重复利用。航空电子系统座舱综合显示设计的应用实例,显示了该设计方法的有效性。

Spiral development for avionics based on prototyping

In order to overcome the shortcomings of waterfall model in the development of avionics system,a spiral development method for avionics based on prototyping is presented.The focus on the spiral development is to verify the design concepts and system requirements and to avoid large modification in later development due to errors raised in early design phase.Also graphical design and prototype simulation are emphasized to overcome the designing error due to requirement misunderstanding.System models are used to verify and validate the design iteratively and to reuse in system design.An example is applied to show the effectiveness of the spiral development process.
