The recent convergence between two industrial transitions towards digitalization on the one side and servitization on the other side led to the new business strategies of digital servitization and smart PSS delivery. While inheriting from the previous scientific literature on PSS, because of the multiple impacts of digitalization in the overall system, the processes of ensuring the design and engineering of smart PSS solutions poses new challenges. This research addresses the specific needs to develop conceptual prototypes of smart PSS value offers, at early stages of the design process. The paper presents the development and experimentation of a modelling language and its associated modelling toolkit (sPS²Modeller). The application case study addresses the design of a smart PSS in the field of heating appliances, developed in collaboration with the company elm.leblanc, Bosch Group – France.

最近，一方面向数字化迈进，另一方面向服务化迈进，这两个产业转型之间的融合催生了数字服务化和智能 PSS 交付的新业务战略。在继承之前关于PSS的科学文献的同时，由于数字化对整个系统的多重影响，确保智能PSS解决方案的设计和工程的过程提出了新的挑战。这项研究解决了在设计过程的早期阶段开发智能 PSS 价值提供的概念原型的特定需求。本文介绍了建模语言及其相关建模工具包 (sPS²Modeller) 的开发和实验。该应用案例研究涉及加热设备领域的智能 PSS 设计，该设计是与法国博世集团的 elm.leblanc 公司合作开发的。
