Model-based Life-cycle Fault Management Method for Manned Lunar Missions
Fault management constitutes an essential approach for controlling risks in complex systems and needs to be implemented in every stage of the system's development and application.With the application of model-based systems engineering(MBSE)in space engineering,it becomes imperative to integrate model-based fault management into the model-based systems development throughout the entire life cycle.In this paper,from a technical perspective,a model-based life-cycle fault management approach is proposed for the manned lunar mission,based on the MBSE methodology and traditional fault management methods.The context of the proposed method encompasses model-based fault management concept design,architecture design,requirements analysis and derivation,requirements verification and confirmation,fault assessment and analysis,as well as operation and maintenance,and the implementations thereof are also illustrated within the process of MBSE.Finally,the proposed model-based fault management process is applied to the mission level of the manned lunar mission,offering a feasible framework for the future fault management of manned lunar missions.
