Manufacturing companies that were traditionally perceived as product-centered, are today increasingly influenced by a service-oriented theory, which claims that manufacturing companies are driven to shift their business focus towards a strategy where customer-perceived value is in the spotlight, and where products are bundled with services to offer Product-Service Systems (PSS). The need to integrate several knowledge domains (i.e. product development, service development, recycling, etc.) means that industry companies need to move “downstream” knowledge from the entire lifecycle into the early phases of the PSS design process where critical decisions are made. At the same time, this raises the awareness of, and requirements for, methods and tools that support cross-disciplinary team collaboration in the process of designing these PSS solutions. Value co-creation is one strategy to address customer collaboration to develop PSS in a framework that allows different stakeholders to participate in defining design concepts and finding the optimal combination of hardware and service that supplies the desired value. Value co-creation strategy and global collaborative innovation are essential for manufacturing companies to explore new ways of designing PSS. The thesis summarizes the research performed by the author, as an industrial Ph.D. student and director for system innovation at BIGmind Innovation. This thesis aims to study and explore the motivation for, and challenges of, working with value co-creation for PSS design by global manufacturing companies. Firstly, the empirical research determined that there are different challenges that global manufacturing companies and product development face when designing PSS. The work involves exploring value co-creation via a customer collaborative design platform and experience prototyping for product-service system design. The research shows that there is a lack of knowledge about guidelines and processes for collaboration in value co-creation. The research emphasizes that the PSS design methodologies of today neglect to specify the roles and responsibilities of the actors who co-create PSS offerings, and there is a lack of understanding of the entire process and how it is implemented in industrial practice when developing solutions. Conclusions from this work suggest that government policies can make a fast and major impact on the demand for innovations and PSS development. Additionally, a value co-creation approach promotes large-scale user participation in the early phase of PSS design. To enhance stakeholder participation and gather feedback, experiential prototypes were utilized during the conceptual design phase of the PSS design. To support further development in the area of value co-creation, the Future Innovation Framework (FIF) is proposed as a mechanism to facilitate the adoption and use of value co-creation of PSS design. This thesis discusses the implications, opportunities, and challenges of the FIF for industrial PSS design. The thesis concludes with a discussion on the possibility of using value co-creation for PSS design in different industry domains in the future.

In response, manufacturing companies are increasingly adopting service-oriented business models through digital servitization, driving the emergence of smart Product Service System (sPSS). However, the inherent complexity and need for collaborative innovation in smart PSS design requires manufacturing companies to adopt innovative design approaches that enable value-adding solutions to customers. This research addresses critical gaps in early-stage of smart PSS design, particularly in leveraging Digital Twins (DT) technology to facilitate value co-creation and support design decision-making. Despite growing interest in Digital Twins and virtual simulations, their practical application in smart PSS design remains limited, highlighting the need for new design approaches that foster collaboration and innovation in the early design stages. To address these challenges and opportunities, this research integrates literature reviews, case studies, and empirical analysis to propose the Future Innovation Framework (FIF) and the Super-System Digital Twins (SSDT) approach for smart PSS development. Through industrial case studies, the research provides practical insights and introduces a Digital Twins approach that supports the successful implementation of smart PSS design in the context of global manufacturing companies. The findings indicate that the proposed Digital Twins approach significantly enhances concept visualization, decision-making and design prototyping in smart PSS design. Future research should focus on refining the Future Innovation Framework (FIF) and Super�System Digital Twins (SSDT) approach, exploring their scalability across various industries, and incorporating advanced AI techniques to maximize their potential. In summary, this research contributes to the theoretical and practical advancements in smart PSS design by demonstrating how FIF and SSDT can foster a more effective and innovative approach in global manufacturing companies. The proposed approach provides a robust foundation for future research and industrial applications, promoting the development of sustainable and competitive smart PSS solutions.

This integration aims to innovate business propositions, hardware, and services. However, gaps persist in developing DT environments to support earlystage collaborative innovation for sPSS, and limited studies explore how real-time synchronized
digital replicas enhance value co-creation in sPSS. This paper addresses this gap by presenting a framework and practical example of integrating value-driven decision support into early sPSS conceptual design. A case study on Smart Electric Vehicle (SEV) development, conducted with a global automotive OEM, demonstrates the framework's efficacy. Through qualitative data analyses based on an experimental validation in case company, the DT proves effective in aiding decision-makers to select value-adding configurations within specific scenarios. Furthermore, the DT serves as a visual decision-making tool, fostering collaboration across diverse teams within the automotive company. This collaboration facilitates value creation across practitioners with varied backgrounds, emphasizing the DT's role in enhancing early-stage innovation and co-creation processes in the sPSS domain.

However, automatic operation strategies have high frequency of manual override, which complicates the assurance of the expected operation effect. One of the fundamental reasons for this phenomenon is that the automatic operation strategy fails to consider the varying preferences of occupants with respect to the indoor environment and control habits of the ECS. Therefore, considering the personalized preferences and habits of occupants and actualizing intelligent operation are essential to ensuring occupants’ comfort and improving energy saving via the automatic operation
of the ECS. Based on this concept, this study divided the consideration of personalized factors in intelligent operation into two stages: determining occupants’ preferences and habits and formulating the operation strategy accordingly. We reviewed research related to these two stages, and extracted the relevant information needed to propose guiding concepts for intelligent operation. Occupants’ preferences through physiological parameters and application to intelligent operation strategy were inferred to effectively achieve the operation concepts above. The results of this study reveal research gaps and offer guidelines for considering personalized factors in the intelligent operation of ECSs

In this research we study the emergence of PSS solutions in the Chinese market via a selected case study on e-scooters, based on the governmental decision to ban fossil-fuel scooters in the late 90s and how this has spurred both a fossil-to-electric transformation and a product-to-function transformation. As seen in this research PSS is also an approach that is working well in the Eastern society and especially in China, based on governmental policies. It is gradually being adopted and applied in local industries significantly by China's leading internet companies (Didi, Alibaba etc). The PSS concept represented by e-bike cases in China has gradually penetrated into different industries. With governmental decisions as the key turn-point, it can be seen in practice and development that China's related service industry is using e-bike PSS to carry out the new business model from selling e-bikes to providing service-oriented solutions.
