摘　　要：针对综合模块化航空电子系统的复杂性和传统瀑布式开发方法存在的问题与挑战,在V型开发模型的基础上提出了一种基于模型和原型仿真的综合模块化航空电子系统的开发方法。该方法通过在需求捕获、方案设计和工程开发阶段分别构建相应的原型系统进行仿真与验证,实现对系统需求进行早期需求确认与设计验证(V&V)、原型仿真与集成。采用该方法的好处是通过原型仿真,系统设计师可以在开发早期向用户展示他们的设计成果,以满足用户的需求;可以帮助系统开发人员以低成本实现连续的虚拟集成和迭代确认与验证,从而缩短系统研制周期,降低系统开发成本。飞行管理系统开发应用案例表明了该方法有效性。In view of the complexity of integrated modular avionics system and the problems and challenges of traditional waterfall development method,an approach to integrated modular avionics(IMA)system based on prototype simulation is proposed on the basis of V-type development model.In this method,the corresponding prototype systems are built in the Requirements Capture Phase,System Design Phase and Engineering Development Phase respectively for simulation and verification,which realize the early validation of system requirements,system design verification and prototype simulation.The advantage of this method is that system designers can show their design results to customers at the early stage of development to meet the needs of customers via prototype simulation.It can help system developers realize continuous virtual integration and iterative validation and verification(V&V)at low cost,thus shortening the system development cycle and reducing the system development cost.An application case of flight management system(FMS)shows the effectiveness of the method.
