摘要：
针对复杂系统设计过程缺乏早期可靠性评估的问题，提出一种基于模型的系统工程方法支持复杂系统的设计及可靠性评估。结合复杂系统的研发特点，提出一种基于“使命、运行、功能、逻辑、物理、可靠性”的基于模型的系统工程（model-based systems engineering, MBSE）建模方法，支持复杂系统设计和可靠性评估；利用基于“图、对象、属性、点、关系、角色”的系统建模语言KARMA对上述过程进行统一表达；通过KARMA的代码生成功能实现图模型到计算模型的映射，完成复杂系统可靠性的评估；将方法应用于液压系统案例，结果表明所提方法对于复杂系统设计和评估具备有效性。

Abstract：
To solve the problem of lack of early reliability evaluation in complex system design process, a MBSE (model-based system engineering) method was proposed to support the design and reliability evaluation of complex systems. With the characteristics of complex system development, a MBSE modeling method based on MOFLP-R(mission, operation, function, logic, physics and reliability) was proposed to support design and reliability assessment of complex system. KARMA, a system modeling language based on GOPPRR(graph, object, property, point, relationship and role), was used to express the MOFLP-R process. Then, in order to evaluate the reliability of the complex system, the code generation was used to map the diagram to the numerical model. Finally, the method was applied to a hydraulic system case and the results showed that the proposed method is effective for complex system design and evaluation.
