摘要
飞机研发是一个旷日持久的多年过程。在飞机的概念设计阶段,就需要对采用新能源和颠覆性系统技术的新型概念飞机进行研究,以实现航空业的可持续发展。当前的开发周期需要加快,以缩短新型飞机的上市时间并降低开发成本,同时还要处理系统技术的复杂性和不确定性。因此,本文提出了一个采用基于模型的系统工程方法进行基于知识的系统架构设计的整体框架。该框架旨在为工程师保存和提供知识,即有关现有系统架构的信息、数据和经验。所开发的框架包括一个数据库概念、一种基于模型的系统架构方法和一个与整体系统设计软件工具 GeneSys 的接口。根据对不同建模语言和工具的评估,MathWorks System Composer 被选为最适合基于知识的系统架构设计的工具。然后,在设计新型氢动力概念飞机时,通过保存和重用形式化知识来演示所开发的框架。机载系统架构模型保存在数据库中,并可自动重新创建,从而缩短了开发时间。完整的图形表示法还不能以形式化的方式存储,这在一定程度上削弱了基于模型的系统架构的清晰表示法的优势。不过,这并没有降低自动再现和评估能力。
Model-Based Framework for Data and Knowledge-Driven Systems Architecting Demonstrated on a Hydrogen-Powered Concept Aircraft
Aircraft development is a protracted process over many years. Novel concept aircraft with new energy sources and disruptive systems technologies are investigated during the aircraft conceptual design phase with the goal to achieve sustainable aviation. Current development cycles need to be accelerated to reduce time to market and development costs of novel aircraft, while still handling complexity and uncertainty of systems technologies. Therefore, a holistic framework for knowledgebased systems architecting using a model-based systems engineering approach is presented. This framework has the purpose to conserve and provide knowledge, that is, information, data, and experiences about existing systems architectures, to the engineer. The developed framework consists of a database concept, a method for model-based systems architecting, and an interface to the overall systems design software tool GeneSys. Based on evaluating different modeling languages and tools, MathWorks System Composer is selected as most suitable tool for knowledge-based systems architecting. The developed framework is then demonstrated by conserving and reusing formalized knowledge for the design of a novel hydrogen-powered concept aircraft. On-board systems architecture models are saved in a database and automatically recreated reducing development time. The complete graphical representation could not yet be stored in a formalized manner partly reducing the advantage of a clear representation of model-based systems architecting. However, this did not reduce automatic recreation and evaluation capabilities.
