基于MBSE和图数据工程的系统分析方法
An Approach for System Analysis with MBSE and Graph Data Engineering
摘要：
基于模型的系统工程旨在为正在开发的系统创建一个模型，覆盖整个系统的详细程度，允许定义和理解其行为，并允许基于模型定义任何接口和工作包。一旦建立了这样一个模型，就可以获得进一步的好处，例如分析系统内复杂的技术相关性。通过将模型显示为正式图并对其进行查询，可以获得各种见解。为了实现此类查询，需要设计一个图模式，该模式允许将模型转换为图数据库。在本文的过程中，我们讨论了一个图形模式和MBSE建模方法的设计，使深入的系统分析和异常解决复杂的嵌入式系统。模式和建模方法旨在回答诸如如果组件中存在电气短路会发生什么之类的问题。哪些其他组件现在离线，哪些数据无法再收集？或者，如果某个条件不能满足，可以建立哪些替代路由来达到系统的某个状态。我们建立在小型航天器的资格和操作的用例上。MBSE模型的结构和行为元素被转移到图形数据库中，在该数据库中对系统进行分析。该模式由MagicDraw到Neo4j的适配器实现。MOVE-II空间飞行任务的例子显示了一些复杂的分析。
英文摘要：
Model-Based Systems Engineering aims at creating a model of a system under development, covering the complete system with a level of detail that allows to define and understand its behavior and enables to define any interface and workpackage based on the model. Once such a model is established, further benefits can be reaped, such as the analysis of complex technical correlations within the system. Various insights can be gained by displaying the model as a formal graph and querying it. To enable such queries, a graph schema needs to be designed, which allows to transfer the model into a graph database. In the course of this paper, we discuss the design of a graph schema and MBSE modelling approach, enabling deep going system analysis and anomaly resolution in complex embedded systems. The schema and modelling approach are designed to answer questions such as what happens if there is an electrical short in a component? Which other components are now offline and which data cannot be gathered anymore? Or if a condition cannot be met, which alternative routes can be established to reach a certain state of the system. We build on the use case of qualification and operations of a small spacecraft. Structural and behavioral elements of the MBSE model are transferred to a graph database where analyses are conducted on the system. The schema is implemented by an adapter for MagicDraw to Neo4j. A selection of complex analyses are shown on the example of the MOVE-II space mission.
