Abstract

Rapid changes in customer needs (CNs) and technology force businesses to develop new products to compete. Functional requirements (FRs) and non-functional requirements (NFRs) are created when CNs are correctly interpreted. FRs specify what the product must do, whereas NFRs specify how a system must behave. The study presents a comprehensive framework that helps product developers accurately and quickly extract the essential NFRs. This is because there is still no agreement in the requirements engineering community regarding which NFRs should be elicited for developing a system and how they should be applied and documented. Moreover, the majority of research in this area has either concentrated more on the field of software development or given more attention to applying FRs and less attention to NFRs. The presented framework applies the integrated approaches of QFD, DSM, and hesitant fuzzy sets (HFS). Design for eXcellence is also used to ensure that system quality attributes, such as NFRs, are considered during the development process. The framework was used to develop a solar power system, and the results indicated that the primary NFRs essential for system development are availability, reliability, maintainability, modularity, flexibility, and extensibility.

利用犹豫模糊 QFD-DFX 方法，基于可再生能源行业的非功能性需求进行新产品开发

客户需求（CN）和技术的快速变化迫使企业开发新产品来参与竞争。功能需求（FRs）和非功能需求（NFRs）是在正确理解 CNs 后产生的。功能需求说明了产品必须做什么，而非功能需求则说明了系统必须如何运行。本研究提出了一个综合框架，可帮助产品开发人员准确、快速地提取基本的 NFR。这是因为需求工程界对开发系统时应提取哪些 NFR 以及如何应用和记录这些 NFR 还没有达成一致意见。此外，这一领域的大多数研究要么更多集中在软件开发领域，要么更多关注 FRs 的应用，而较少关注 NFRs。所介绍的框架应用了 QFD、DSM 和犹豫模糊集（HFS）的综合方法。卓越设计 "还用于确保在开发过程中考虑到系统质量属性，如 NFR。该框架被用于开发太阳能发电系统，结果表明，系统开发所必需的主要 NFR 是可用性、可靠性、可维护性、模块性、灵活性和可扩展性。

期刊介绍： The journal provides a focus for the dissemination of new results about the elicitation, representation and validation of requirements of software intensive information systems or applications. Theoretical and applied submissions are welcome, but all papers must explicitly address: -the practical consequences of the ideas for the design of complex systems -how the ideas should be evaluated by the reflective practitioner The journal is motivated by a multi-disciplinary view that considers requirements not only in terms of software components specification but also in terms of activities for their elicitation, representation and agreement, carried out within an organisational and social context. To this end, contributions are sought from fields such as software engineering, information systems, occupational sociology, cognitive and organisational psychology, human-computer interaction, computer-supported cooperative work, linguistics and philosophy for work addressing specifically requirements engineering issues.
