    With the digital revolution, the IoT (Internet of Things) platform approach emerges as a supportive way for the implementation of IoT platform-based Product-Service System (PSS) offerings. To exploit the full potential of the platform economy and considering the complexity of the multitude of different actors in all the lifecycle stages, value creation architectures for digital and service platforms are one of the critical points to develop. In this work, the concept of Platform-based PSS is presented, and for representation purposes, an extension of the RAMI 4.0 reference model has been proposed. Specifically, the ecosystem perspective has been added to RAMI 4.0, to approach Platform-based PSS with a multi-actor lens. Moreover, the different contributions and benefits of the main participants in Platform-based PSS are illustrated. Therefore, three different scenarios have been exemplified with the proposed RAMI 4.0 extension relating the actors' possibilities to contribute to Platform-based PSS to the level of openness of a platform.

    Intense collaboration within networks of stakeholders characterizes current engineering design processes. In these, engineers use IT systems to create artifacts, which manifest their knowledge allowing its circulation. Still, a research gap exists regarding the understanding of kinds, relations and interdependencies between IT systems, artifacts and knowledge types. This article addresses this gap by presenting results of a systematic literature review. The results contribute to close the mentioned gap, give insight on focusses of current research and identify further need for investigations.

    As a result of the growing demand for highly customized and individual products, companies need to enable flexible and intelligent manufacturing systems. Such new production systems, so called ""Cyber Physical Productions Systems"" (CPPS) aim the vision of interlinked and autonomous production. The research project VIB-SHP envisions controller validation of manufacturing system covering aspects of asynchronous communicating, intelligent and autonomous acting production equipment and a service based production IT. To enable manufacturing system designers to validate CPPS, a software framework for virtual prototyping has been developed. A multi-disciplinary construction kit integrates discipline specific models and manages them in a PLM solution. The usage of the construction kit enables manufacturing designers to apply virtual technologies and ease the integration in the production-IT. The presented approach resolves the sequential design process for the development of mechanical, electric and software elements and ensures the consistency of these models. With the help of a BOM- and signal-based alignment of the discipline specific models in an integrated mechatronic product model, the communication of design status and changes is improved. The re-use of already specified and designed modules enable quick behavior modeling, code evaluation as well as tangible user interaction with the virtualized assembly system.
