标题： KARMA Approach supporting Development Process Reconstruction in Model-based Systems Engineering

摘要： 模型重构是一种用于驱动基于模型的系统工程中复杂系统开发过程发展的方法。 目前，在系统的迭代设计过程中，缺乏一种有效的方法来管理开发需求的变化，例如开发周期需求和成本需求，并实现系统开发过程模型的重构。 为了解决这些问题，本文提出了一种模型重构方法，以支持开发过程模型。 首先，基于GOPPRR-E元建模方法的KARMA语言被用来统一形式化基于不同建模语言构建的过程模型。 其次，引入了一个模型重构框架。 该框架以基于结构化开发需求的自然语言作为输入，采用自然语言处理技术分析开发需求文本，并提取结构和优化约束信息。 然后，在进行结构重组和算法优化后，获得符合开发需求的开发过程模型。 最后，以飞机机载维护系统的开发过程为例进行了案例研究。 结果表明，该方法可以显著提高开发过程的设计效率。 显示英文摘要

摘要： Model reconstruction is a method used to drive the development of complex system development processes in model-based systems engineering. Currently, during the iterative design process of a system, there is a lack of an effective method to manage changes in development requirements, such as development cycle requirements and cost requirements, and to realize the reconstruction of the system development process model. To address these issues, this paper proposes a model reconstruction method to support the development process model. Firstly, the KARMA language, based on the GOPPRR-E metamodeling method, is utilized to uniformly formalize the process models constructed based on different modeling languages. Secondly, a model reconstruction framework is introduced. This framework takes a structured development requirements based natural language as input, employs natural language processing techniques to analyze the development requirements text, and extracts structural and optimization constraint information. Then, after structural reorganization and algorithm optimization, a development process model that meets the development requirements is obtained. Finally, as a case study, the development process of the aircraft onboard maintenance system is reconstructed. The results demonstrate that this method can significantly enhance the design efficiency of the development process.
