Functional design is regarded as a design activity primarily aimed at clarifying customer needs, and developing the functional architecture and solution concepts for a system under development. Existing functional design approaches are mainly focused on how to assist designers in searching for solution principles for desired products, which, however, do not adequately take into account the interactions between a smart system under development and its environment, and cannot explicitly represent the complex functional logic of the system, resulting in that they cannot effectively assist designers in the functional design of smart systems. Therefore, this paper proposes a scenario-integrated approach for functional design of smart systems to address the above issues. Based on the concept of scenario in software engineering, the proposed approach explicitly elaborates how to employ scenarios to express subjective customer needs and how to generate the functional architectures and the corresponding solution concepts through a structured process. The functional design of the automated doors-unlocking system of a smart vehicle is employed to illustrate the proposed approach, which also demonstrates that the proposed approach is suitable for functional design of smart systems.

一种场景集成的智能系统功能设计方法

功能设计被认为是一种设计活动，主要旨在阐明客户需求，并为正在开发的系统开发功能架构和解决方案概念。现有的功能设计方法主要集中在如何帮助设计人员寻找所需产品的解决方案原则，而没有充分考虑正在开发的智能系统与其环境之间的交互，并且不能明确表示复杂的功能。系统逻辑，导致无法有效协助设计人员进行智能系统的功能设计。因此，本文提出了一种场景集成的智能系统功能设计方法来解决上述问题。基于软件工程中的场景概念，所提出的方法明确阐述了如何使用场景来表达主观客户需求以及如何通过结构化流程生成功能架构和相应的解决方案概念。采用智能汽车自动门解锁系统的功能设计来说明所提出的方法，这也表明所提出的方法适用于智能系统的功能设计。
