NASA基于模型的任务保证研究

Research on NASA Model Based Mission Assurance

2015年NASA提出了基于模型工程的任务保证(Model Based Mission Assurance, MBMA),为传统的产品保证带来了工具方法手段和管理理念的巨大变化。从MBMA的发展历程、基于模型的任务保证(Model Based Systems Engineering, MBSE)对MBMA的支持、 MBMA关键要素,以及NASA实施MBMA对我们的启示几个方面,对NASA提出的MBMA进行研究和阐释,认为推行MBSE的时机已经成熟,应该充分利用MBSE的优势开展可靠性工作,同时要大力开展MBSE模型、过程和工具的研究与开发。

In 2015, the model based mission assurance(MBMA) was introduced by NASA, which improved mission assurance process, standards and tools. The history and key elements of MBMA are discussed. Some best practices that can be applied to aerospace product assurance are summarized. It’s time to implement the model based mission assurance. It should apply the model based systems engineering to quality and reliability assurance,while the model based mission assurance models,process and tools should be developed.
