介绍基于模型的系统工程开发流程与方法及其在某型复杂飞控系统方案设计中的应用。相比于传统设计方法,利用模型基线取代文档基线能够更好的应对现代大型系统的复杂性,利用系统工程方法进行自顶向下的设计也能够更好地保证系统设计过程的一致性、需求验证的完整性和系统的可测试性。最后通过对模型的仿真验证,实现了需求设计到验证的完全覆盖,在系统硬件实现前完整地模拟了系统的功能行为,并完成复杂系统基于模型的功能故障模式与影响分析,降低了系统研制风险等级。
This paper introduces the process and method of system engineering development based on model and its application in the scheme design of some complex flight control system. Compared with the traditional design method, using the baseline of the model to replace the baseline of the document can better cope with the complexity of the modern large-scale system. Using the top-down design of the system engineering method can better ensure the consistency of the system design process. Verification integrity and system testability. Finally, through the simulation of the model, the complete coverage from requirement design to verification is realized, and the function and behavior of the system are completely simulated before the system hardware is implemented, and the model-based function failure mode and influence analysis of the complex system is completed, which reduces the system development Risk level.
