AdaptUI: A Framework for the development of Adaptive User Interfaces in Smart Product-Service Systems

Smart Product–Service Systems (S-PSS) represent an innovative business model that integrates intelligent products with advanced digital capabilities and corresponding e-services. The user experience (UX) within an S-PSS is heavily influenced by the customization of services and customer empowerment. However, conventional UX analysis primarily focuses on the design stage and may not adequately respond to the evolving user needs during the usage stage and how to exploit the data surrounding the use of S-PSS. To overcome these limitations, this article introduces a practical framework for developing Adaptive User Interfaces within S-PSS. This framework integrates ontologies and Context-aware recommendation systems, with user interactions serving as the primary data source, facilitating the development of adaptive user interfaces. One of the main contributions of this work lies on the integration of various components to achieve the creation of Adaptive User Interfaces for digital services. A case study of a smart device app is presented, to demonstrate the practical implementation of the framework, with a hands-on development approach, considering technological aspects and utilizing appropriate tools. The results of the evaluation of the recommendation engine show that using a context-aware approach improves the precision of recommendations. Furthermore, pragmatic aspects of UX, such as usefulness and system efficiency, are evaluated with participants with an overall positive impact on the use of the smart device

Digital Manufacturing Platforms in the Industry 4.0 from Private and Public Perspectives

The fourth industrial revolution is characterized by the introduction of the Internet of things (IoT) and Internet of Services (IoS) concepts into manufacturing, which enables smart factories with vertically and horizontally integrated production systems. The main driver is technology, as Industry 4.0 is a collective term for technologies and concepts of value chain organization. Digital manufacturing platforms play an increasing role in dealing with competitive pressures and incorporating new technologies, applications, and services. Motivated by the difficulties to understand and adopt Industry 4.0 and the momentum that the topic has currently, this paper reviews the concepts and approaches related to digital manufacturing platforms from different perspectives: IoT platforms, digital manufacturing platforms, digital platforms as ecosystems, digital platforms from research and development perspective, and digital platform from industrial equipment suppliers

Implementation of a holistic digital twin solution for design prototyping and virtual commissioning

Abstract Industry 4.0 has ushered in a new era of digital manufacturing and in this context, digital twins are considered as the next wave of simulation technologies. The development and commissioning of Cyber Physical Systems (CPS) is taking advantage of these technologies to improve product quality while reducing costs and time to market. However, existing practices of virtual design prototyping and commissioning require the cooperation of domain specific engineering fields. This involves considerable effort as development is mostly carried out in different departments using vendor specific simulation tools. There is still no integrated simulation environment commercially available, in which all engineering disciplines can work collaboratively. This presents a major challenge when interlinking virtual models with their physical counterparts. This paper therefore addresses these challenges by implementing a holistic and vendor agnostic digital twin solution for design prototyping and commissioning practices. The solution was tested in an industrial use case, in which the digital twin effectively prototyped cost‐efficient solar assembly lines

Analyzing the risks of digital servitization in the machine tool industry

The machine tool industry plays a major role in the execution of high-quality and efficient complex manufacturing processes. The adoption of digital technologies can transform production systems into more connected, adaptive, efficient, and potentially sustainable systems. A key enabler of this transformation is servitization, a business model that builds on digitalization and data capture to deliver value through services. Digital services for machine tools typically use data obtained through highly connected manufacturing environments, providing visibility of complex lifecycles, and enabling better decision-making. However, an understanding of digital servitization to support the machine tools industry is still emerging and for most industrial actors the potential risks are unclear. The findings of this study describe potential applications of digital servitization in the machine tool industry, synthesize the identified risks from practitioners’ perspectives, and provide mitigation and contingency activities. This study contributes to bridging the gap between theory and practice by clarifying companies’ needed considerations before implementing digital services in the machine tool industry
