Research on Scenario Modeling of Civil Aircrafts Based on DoDAF
摘要
In traditional text-based systems engineering (TSE) for scenario modeling of civil aircrafts, there are problems such as insufficient linkage between requirements and design, as well as difficulties in traceability. To address these problems, this paper proposes a framework architecture modeling method based on Department of Defense Architecture Framework (DoDAF). By means of multi-view integration and hierarchical modeling analysis, the full-process traceability of scenario requirements can be realized. First, in conjunction with the DoDAF Meta Model (DM2), this paper analyzes the constraint relationships from different perspectives and proposes a constraint-based architectural modeling development process. Second, it establishes a mapping mechanism between DoDAF and SysML, bridging the relationship between system-of-systems level capabilities and system-level functions. Finally, these methods are demonstrated using the aircraft ground deceleration scenario as an example, forming a traceable requirements catalog that ensures consistency between requirements and modeling, and supporting collaborative de-sign at the system-of-systems level.
