This work presents a model of the process of conceptual design studies which use the concurrent engineering approach. Concurrent conceptual design is an integrated system development approach, to rapidly explore feasible design solutions by parallelizing the work of experts. This approach is characterized by a multidisciplinary team of experts collaborating in a co-located manner. Albeit the conceptual design phase requires creative problem solving, teamwork requires coordination, and would profit from a shared understanding of the design process. Based on a survey among experts from 15 different organizations, and practice documented in literature, we propose a model of the underlying design process. This work extends our previous work on a coordination method for concurrent design and provides validation of the process model via case studies and expert interviews. The proposed process model is formalized in SysML diagrams. It can be used to help program coordinators and train engineers of different disciplines on the methodology of concurrent conceptual design, as well to serve as a baseline for implementing the methodology in new organizations.

空间系统并行概念设计的过程模型

这项工作提出了使用并行工程方法的概念设计研究过程的模型。并行概念设计是一种集成的系统开发方法，通过并行化专家的工作来快速探索可行的设计解决方案。这种方法的特点是多学科专家团队以同地合作的方式进行合作。尽管概念设计阶段需要创造性地解决问题，但团队合作需要协调，并且可以从对设计过程的共同理解中受益。基于对来自 15 个不同组织的专家的调查以及文献中记录的实践，我们提出了一个基本设计过程的模型。这项工作扩展了我们之前在并行设计协调方法方面的工作，并通过案例研究和专家访谈对过程模型进行了验证。建议的过程模型在 SysML 图中形式化。它可用于帮助项目协调员和培训不同学科的工程师关于并发概念设计的方法，以及作为在新组织中实施该方法的基线。
