A conceptual data model promoting data-driven circular manufacturing

Circular economy (CE) paradigm fosters manufacturing companies’ sustainability taking place through different circular manufacturing (CM) strategies. These strategies allow companies to be internally committed to embrace circular values and to be externally aligned with several stakeholders not necessarily belonging to the same supply chain. Nevertheless, these CM strategies adoption is limited by heterogeneous barriers, among which the management and sharing of data and information remain the most relevant ones, bounding the decision-making process of manufacturers in CM. Moreover, the extant literature unveiled the need to structure data and information in a reference model to make them usable by manufacturers. Therefore, the goal of the present work is to propose a reference model by developing a conceptual data model to standardise and structure the necessary data in CM to support manufacturers’ decision-making process. Through this model, data and information to be gathered by manufacturers are elucidated, providing an overview of which ones should be managed internally, and shared externally, clarifying the presence of their mutual interdependencies. The model was conceptualised and developed relying on the extant literature and improved and validated through academic and industrial experts’ interviews

How Lean Thinking affects Product Service Systems Development Process

PSS development involves together, through the servitization phenomenon, both manufacturing and service workers carrying great potential to pursue industrial competitiveness, customer satisfaction and sustainable improvement. The belief is that the development level of PSS design is slowly evolving through a path strongly driven by the evolution of the technology and the progressive involvement of the industry in its application. However companies still need best practices able to improve the PSS development processes performances in a more systematic way. Lean techniques already managed to provide these procedures in a product context allowing the improvement of both product manufacturing and product development processes. The evolution of Lean to an intangible dimension also guided companies' convergence strategy from mass production to mass customization in an efficient and effective way. For this reasons the paper aims to investigate the literature about Lean Thinking evolvement from manufacturing to design phases, as well as from product to service. On this basis, the definition of which are Lean Thinking aspects which could positively affect also PSSs Development will enable the authors to understand which are the more suitable tools to develop Lean PSS and how to provide companies best practices able to improve the PSS development processes performances in a more systematic way. This opens the way to new opportunities and challenges through many further research and industrial projects

The impact of IoT technologies on product-oriented PSS: The 'home delivery' service case

The contribution aims to evaluate the impact that IoT technologies can have on PSS and services. Particularly, the analysis considers two dimensions: the typology of services enabled by the IoT, and the PSS lifecycle phases of the home delivery. By means of multiple use cases, authors found out that IoT technologies have huge impacts both on order placement and delivery phases. Particularly, they have a two-fold advantage for the main stakeholders involved: on one side they speed up operations and on the other they reduce the number of activities for completing the overall home delivery process

Testing the methodology to generate Design for Product Service Supportability (DfPSS) Guidelines and Rules: an application case

The industrial world is today navigating from a traditional product-based business to a new more complex solution-based orientation, pushed by new technologies, a multiple functionalities demand and a change in the customer value perception. Several are the methods and tools proposed in literature to aid manufacturers to design those solutions in an integrated and systematized way but none of them is really able to consider together product and service components, according to both company and customer views. In this context, a methodology generating new Design for X (DfX) guidelines to support the early integration of service features already in the product design of PSS has been proposed by the authors. This methodology can raise engineers’ consciousness in designing PSSs in a systematic and integrated way and provides insights into the link between the design process of PSS and the design knowledge generation in terms of guidelines and rules. In particular, the objective of this paper is to test this methodology through an application case. The test, following a theory building procedure, contributes to obtain the final methodology design, providing a double result: industrial experts’ feedbacks, giving to the authors a major awareness of its strengths and weaknesses, and new industry-specific PSS design guidelines and rules

The Design for Product Service Supportability (DfPSSu) methodology: generating sector-specific guidelines and rules to improve Product Service Systems (PSSs)

Nowadays manufacturers’ need to systematically develop innovative integrated solutions is increasingly pushed by new technologies, a multiple functionalities demand and a change in the customer value perception. For these reasons, it is very complex for Product Service Systems (PSS) providers to fulfil all the design requirements: designers must consider all the objectives the PSS wants to achieve during its whole lifecycle according to different criteria, which are often to be considered according to a trade-off balance. At present, Design for X (DfX) design methods represent the most important attempt to enhance product development according to certain characteristics or lifecycle phases: authors believe they can also support the PSS design, redesigning or enhancing products in certain X-dimensions, in particular those ones related to “service supportability”. On this basis, a methodology generating new Design for X (DfX) guidelines has been proposed: in this paper an application case in the mold industry shows how a physical product can be improved when a service has to be added and integrated. At the same time, new industry-specific PSS design guidelines and rules are proposed

The role of Internet of Things (IoT) technologies for individualisation and service quality of a PSS

Nowadays, product manufacturers are compelled to increasingly becoming Product Service System (PSS) providers for surviving and managing the increased global competition. 20% of the enterprises have already integrated services in their product offerings. Meanwhile, the Internet of Things (IoT) is expected to grow significantly in the next years. Smart products are growing fast and are expected to reach 212 billion entities at the end of 2020. From an economic point of view, it is estimated that the impact of IoT is in a range of $2.7 to$6.2 trillion by 2025. IoT is surely an enabler of PSSs, allowing the collection and sharing of vast quantities of information along the whole solution life. This article aims to evaluate the impact that IoT technologies can have on the PSS provision when aiming at the satisfaction of highly diverting customer needs. Particularly, the analysis considers three dimensions: the typology of services enabled, the customization approach enabled, and the service quality gaps disclosed by IoT. By means of multiple use cases, the authors found out that IoT technologies have a huge impact on the different phases of the whole PSS lifecycle. Several advantages were detected for the different stakeholders involved in terms of both service efficiency and effectiveness. Based on these results, the strategic contact points to cope with possible trade-offs between the PSS individualization approach and its service quality are proposed

Towards a Lean Product Service Systems (PSS) Design: State of the Art, Opportunities and Challenges

AbstractAs for conventional products, the profit generation and the market success of Product Service Systems (PSS) critically depend on the decisions taken during the initial lifecycle stages, when PSSs are conceptualized, designed, developed and engineered. Successful cases show the adoption of lean techniques in the early stages of products development, impelling the authors to assess the application of the same approaches also to PSS development. For this reasons the paper aims to report the state of the art of PSS Design research, relating this strategic process to the Lean Thinking approaches typically applied in traditional Product Development and Manufacturing. The literature about PSS is classified and Lean Thinking evolvement from product manufacturing to design phases is described. On this basis, the paper defines which are the aspects of Lean Thinking already applied in PSS Development also uncovering gaps and lacks of the methods proposed by the scientific literature so far. This opens the way to new opportunities and challenges through many further research and industrial projects

Biomethane Community: A Research Agenda towards Sustainability

The bioeconomy is an effective solution to align with the sustainability agenda and to meet the pressing calls for action from Cop26 on a global scale. The topic of the circular bioeconomy has gained a key role in the literature, while the theme of energy community is a basic form of social aggregation among stakeholders. This work focuses on biomethane and proposes a framework based on several criteria that are evaluated using a hybrid Analytic Hierarchy Process (AHP) and 10-point scale methodology. The results show that regulation and energy community are considered the two most relevant categories. The overall ranking of criteria sees the stakeholders’ engagement as the most important, followed by more significant subsidies for small- and medium-sized plants and the principle of self-sufficiency applied at the inter-regional level. Subsequently, the Italian Adriatic corridor composed of four MMAP (Marche, Molise, Abruzzo, and Puglia) regions is considered as a case study in order to evaluate the possible environmental (854 thousand tons CO2eqyear) and economic (from 49 million EUR to 405 million EUR in function of plant size) benefits associated with potential biomethane production of 681.6 million m3. It is found that the biomethane community is an enabler of sustainability and this strategy can be used for sharing different natural resources

Building the Value Proposition of a Digital Innovation Hub Network to Support Ecosystem Sustainability

Digital Innovation Hubs (DIHs) play a key role in bolstering European companies to overwhelm innovation barriers and drive Europe as the world’s primary leader in the Industry 4.0 digital revolution; they are one-stop-shop ecosystems able to provide four main functionalities (test before investing, support to find investments, innovation ecosystems, and networking, skills and training). Even if a surge in their diffusion has been registered, their sustainability is still far from being well defined in a structured way. Several approaches and methods are available from literature to ground the sustainability plan of companies’ business. Among them, the first activity to be addressed is the value proposition (VP) analysis, and the most diffused approach is the Value Proposition Canvas (VPC); this paper proposes the application of the VPC (jointly used with other methods from the VP literature) to build the VP of the HUBCAP network (supporting European small and medium-sized enterprises in the adoption of model-based design methods and tools to support cyber-physical system technologies) per each of its four main customer segments (DIHs, academic partners and research and technology organizations, technology/tool providers and technology/tool users). Results highlight the need to characterize the analysis per each of these customers, open up new opportunities to build a structured business model of the network, and constitute a basis for assessing the potential synergies with similar DIH networks. The method proposed can be applied to any other DIH or network of DIH to define their specific VP, ground the strategy to reach their sustainability, and trigger collaborations with each of the four customer segments considered in the analysis
