A new generation of collaborative manufacturing systems where all the components are connected exploiting the Internet of Things is envisioned in the era of Digitalized Manufacturing. Industries nowadays try their best to adapt to digitalized manufacturing paradigm in order to remain competitive and to ensure their sustainability in a globalized world that undergoes a digital transformation driven by advanced technology and connected devices. Products up to now have been designed in every minimum detail to provide the best product experience. However, they are not, still, the most efficient and sustainable solutions. Solutions to fulfill our needs and not another products are mandatory. The phenomenon of manufacturers shifting their business models to add a services dimension to their product offering is widespread. Servitization has allowed manufacturers to maintain their competitive advantage in the face of competitive pressures arising from globalization, and at the same time create greater value for customers. The shift of profit margins from products to services, has transformed traditional production equipment supplier industries to providers of Product-Service Systems (PSS). PSS is a solution resulted from the synergetic integration of tangible and intangible elements coupled with supportive systems (resources and infrastructures) and heterogeneous knowledge describing stakeholders’ viewpoints. The design and planning of such a system involves a complex network of stakeholders coming from private or public Sector. More than that providing an integrated Product-Service System (PSS), as a smart solution, is increasingly offered by industrial machinery and also Energy sector strives to provide services on top of energy selling. In order to contribute to the realization of such a vision, the present thesis investigates the analysis, design, and development of advanced Product-Service Systems in the era of digitalized manufacturing following a collaborative approach. This thesis contributes in three directions. The first one is the Analysis, Design, and Development of advanced PSSs. The analyzed, designed and provided services on top of the provided products can be grouped into three categories namely: Process and health monitoring of manufacturing equipment, Remote maintenance assistance for the preventive and unscheduled maintenance of manufacturing equipment and Energy Management Services which are reflecting to three industrial cases. In particular, following the trends of the digitalized manufacturing and considering that Manufacturing, SMEs and Energy Utilities are at the first positions of the EU agenda, a Machinery Equipment Provider (Original equipment manufacturer - OEM), a Mold Making Small and medium-sized enterprise (SME) and an Energy Supplier are the three industrial cases of this thesis. The PSS “value co-creation” to improve the firm’s capabilities is established by network’s actors collaboration through the whole lifecycle. Due to this complexity, a central point is to support the development process of PSS as such the second contribution of this thesis is the analysis and design of a resource planning tool for Product-service systems production and installation supported by a procurement module as a part of collaborative PSS production. This part explores the consequent changes in production planning in order to tightly integrate products and services and as a result, delivers a Planner capable to support every PSS type. Following that, considering the PSS Complexity, the third direction is the creation of a decision making support methodology for the quantification of PSS customization complexity, considering Industry 4.0 aspects based on the fact that the design and evaluation of Product-Service Systems (PSS) constitute a challenging problem due to its multidimensionality. This challenge becomes bigger when the PSS customization is required, within the new manufacturing paradigm of Industry 4.0. Nevertheless, the literature work regarding the customization of PSS and the PSS investigation within the Industry 4.0 is rare. The proposed PSSs and tools are validated using real data from the aforementioned cases. The opportunity to follow these studies driven by real case studies under the Horizon 2020 “An Integrated Collaborative Platform for Managing the Product-Service Engineering Lifecycle” - ICP4Life project makes this work more interesting and challenging. To this end, the present thesis is divided into 9 chapters. After an introduction (Chapter 1) which examines the vision and motivations behind this work, Chapter 2 reviews the literature related to the main aspects of this study. Accordingly, Chapter 3 presents the methodology followed and also the collaborative approach of the present work. Chapter 4-7 are the core of the thesis and present the four main outcomes including the related industrial applications. In particular, a) the developed Energy Based Offered PSSs, b) the developed Manufacturing Equipment PSSs for process and health monitoring and also for Remote maintenance assistance, c) the PSS production and installation planning methodology and finally d) the Product-Service System complexity calculation methodology are presented. Accordingly, an overview of the results and a discussion of them is given in Chapter 8. Finally, Chapter 9 draws the conclusions, summarizing the main outcomes and pointing out some possible future works.
