论文摘要
工业产品服务系统(IPSS)在多个领域越来越占主导地位。为生产系统,电厂和汽车舰队等工业资产提供的主要增值服务是远程资产维护,监视,控制和重新配置。 IPSS设计师缺乏在系统地得出基础网络物理系统(CPS)IPSS服务的技术设计要求方面支持它们的方法和工具。同时,由于功能强大的,网络的信息技术(IT)和操作技术(OT)基础架构以及传感器和数据的普遍性,使用数字双胞胎(DTS)作为CPS ASET的数字表示变得越来越可行。本文提出了一种指导IPSS设计师进行DT实例的规范和实施的方法,以作为IPSS服务的关键推动力。连续的IT设计构建 - 部署周期概念与CPS的OT域的系统映射是应用方法的核心,这是由利益相关者驱动的要求启发所补充的。关键贡献是一种结构化方法,用于为IPS提供DT实例的技术设计要求。该方法在分布式CPS IPS的评估环境中在现实世界中的用例中进行了验证。
Industrial Product-Service Systems (IPSS) are increasingly dominant in several sectors. Predominant value-adding services provided for industrial assets such as production systems, electric power plants, and car fleets are remote asset maintenance, monitoring, control, and reconfiguration. IPSS designers lack methods and tools supporting them in systematically deriving technical design requirements for the underlying Cyber-Physical System (CPS) IPSS services. At the same time, the use of Digital Twins (DTs) as digital representations of CPS as-sets is becoming increasingly feasible thanks to powerful, networked information technology (IT) and operation technology (OT) infrastructures and the ubiquity of sensors and data. This paper proposes a method for guiding IPSS designers in the specification and implementation of DT instances to serve as the key enablers of IPSS services. The systematic mapping of the continuous IT design-build-deployment cycle concept to the OT domain of CPS is at the heart of the applied methodology, which is complemented by a stakeholder-driven requirements elicitation. The key contribution is a structured method for deriving technical design requirements for DT instances as IPSS. This method is validated on real-world use cases in an evaluation environment for distributed CPS IPSS.
