基于MBSE的飞行器可靠性需求多维捕获与分解技术研究OA

In the aircraft design process,requirement capture is a key step to ensure that the product design meets stakeholders'expectations.Firstly,multi-dimensional capture and decomposition of civil aircraft reliability require-ments are carried out from the scenario dimension and the stakeholder dimension.Secondly,combined with the model based system engineering(MBSE)process,the accuracy and completeness of civil aircraft reliability require-ments capture and validation are realized through the stakeholders identification,reliability requirements capture-validation-modeling,and reliability requirements decomposition-verification-modeling.Finally,using a typical civ-il aircraft system as a case study,the model-based civil aircraft reliability requirements capture and decomposition technology completes the scenario-based and stakeholder-based reliability requirements capture,modeling and vali-dation.A typical system stakeholder reliability requirements MBSE model is obtained.This paper provides the re-quirements for the whole life cycle of the civil aircraft based on the MBSE reliability design process input,and MB-SE methods and solutions for system engineers involved in requirement capture and decomposition of civil aircraft.
