基于模型的系统工程（MBSE）代表了从基于文档的系统工程（DBSE）的传统方法的转变。MBSE促进了系统工程项目的一致性、沟通、清晰度和可维护性，并解决了与成本、复杂性和安全性相关的问题。虽然MBSE的这些潜在好处得到了潜在从业者的普遍认同，但其实施具有挑战性，许多组织在采用MBSE的漫长而曲折的道路沿着努力克服文化和技术障碍。在本文中，我们的目标是通过调查现有的系统工程流程的当前问题所在，以及基于模型的方法可能能够帮助，从工程师的角度在空中客车公司的航天器功能航空电子设备工作，以减轻实施过程。已经开发了一个可重复的过程来获取此信息。我们对25名空客工程师进行了半结构化访谈，他们分别在运营、软件和故障、检测、隔离和恢复部门工作。对获得的数据进行了专题分析，以便从答复中提取共同的主题。本文提出的结果产生了四个建议的应用领域时，考虑应用MBSE功能航空电子：组织建模;早期功能验证;通信和一致性;模板模型框架的开发。
Model-Based Systems Engineering (MBSE) represents a move away from the traditional approach of Document-Based Systems Engineering (DBSE). It is claimed that MBSE promotes consistency, communication, clarity and maintainability within systems engineering projects and addresses issues associated with cost, complexity and safety. While these potential benefits of MBSE are generally agreed upon by would-be practitioners, its implementation is challenging and many organisations struggle to overcome the cultural and technical hurdles along the long and winding road to MBSE adoption. In this paper, we aim to ease the process of implementation by investigating where the current issues with the existing systems engineering processes lie, and where a model-based approach may be able to help, from the perspective of engineers working on spacecraft functional avionics in Airbus. A repeatable process has been developed to elicit this information. Semi-structured interviews have been conducted with 25 Airbus engineers working in Operations, Software and Failure, Detection, Isolation and Recovery. The acquired data has been thematically analysed to extract common themes from the responses. The results presented in this paper have yielded four recommended application areas to consider when applying MBSE to Functional Avionics: organisation modelling; early functional validation; communication and consistency; template model framework development.
