ABSTRACT
In this paper, the aircraft scenario modeling and requirement capture method are studied under the framework of the Department of Defense Architecture Framework (DoDAF) based on Model-Based System Engineering (MBSE). First, the description method is presented based on the DoDAF, basic elements, and the model levels of the aircraft operational scenario respectively. Second, the aircraft requirement capture process and analysis steps are determined based on the aforementioned scenario. Operational requirements can be captured by the interaction between aircraft and various stakeholders in different operational scenarios. Then, the scenario model of a certain civil aircraft, including the flight phase level, the task cell level, and the behavior unit level, is constructed based on the DoDAF. The process of operational requirement capture based on the above model is elaborated in detail. Finally, the results of this paper can be applied to capture the operational requirements of aircraft. More importantly, the results can also be used to connect the market needs with the development process of aircraft. The traceability between market needs and development requirements can be identified effectively.
