摘要

摘要基于模型的系统工程(MBSE)旨在创建正在开发的系统的模型,以一定程度的细节覆盖整个系统,从而定义和理解其行为,并能够基于模型定义任何接口和工作包。一旦建立了模型,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。通过将模型显示为形式图并对其进行查询,可以获得各种见解。要启用此类查询,需要一个图模式,它可以将模型转移到图数据库中。在本文的过程中,我们讨论了图模式和MBSE建模方法的设计,以实现复杂嵌入式系统中的深入系统分析和异常解决,重点是测试和异常解决。模式和建模方法旨在回答以下问题:如果组件中存在电气短路,会发生什么?哪些其他组件现在处于脱机状态,哪些数据无法再收集?如果一个组件变得没有反应,可以建立哪些替代路线来获得它处理的数据。我们以小型航天器的鉴定和操作用例为基础。MBSE模型的结构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。该模式是通过MagicDraw到Neo4J的适配器实现的。MOVE-II太空任务的例子显示了一系列复杂的分析。

An approach for system analysis with model-based systems engineering and graph data engineering
Abstract Model-based systems engineering (MBSE) 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 work package based on the model. Once the 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 is necessary, 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 modeling approach, enabling deep going system analysis and anomaly resolution in complex embedded systems with a focus on testing and anomaly resolution. The schema and modeling 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? If a component becomes unresponsive, which alternative routes can be established to obtain data processed by it. We build on the use case of qualification and operations of a small spacecraft. Structural elements of the MBSE model are transferred to a graph database where analyses are conducted on the system. The schema is implemented by means of an adapter for MagicDraw to Neo4J. A selection of complex analyses is shown in the example of the MOVE-II space mission.
