Economic Objective

The product service system (PSS), as a design concept for integrated products and services, needs to be evaluated in the early design stage to maximize the value for stakeholders of the PSS concept, which is a crucial task for enterprises. However, existing methods focus on the ranking and value assessment of PSS evaluation criteria (e.g., quality, sustainability, cost), ignoring the needs conflict between customer value and economic objectives in PSS design, resulting in decision results that are not applicable to industrial enterprises. Furthermore, the influence of weight preference and uncertain information on solution evaluation is seldom considered when calculating the weight of each criterion. To fill this gap, integrating rough sets and the Shapley value decision approach for product-service system design considering customer value-economic objective trade-off is proposed, which mainly includes two parts: firstly, the best worst method (BWM) and the entropy weight method are integrated to obtain the comprehensive weight of evaluation criteria in the customer value and economic objectives; secondly, the Shapley value method in the coalition game is used to solve the optimal expectation allocation of the two objectives, so as to select the solution closest to the allocation, i.e., the optimal solution. In addition, rough set techniques are used to capture and integrate subjective assessment information originating from DMs under uncertainty. Finally, a case study of the electric forklift design is illustrated to verify the proposed decision model. The decision results show that this approach is more reliable through sensitivity and comparison analysis, and provide a valuable recommendation for enterprises to consider product service in forklift design.

Purpose With the customers’ increasing expectation on the product value, manufacturing enterprises around the world have made significant efforts to provide high value-added services in addition to their traditional product development and manufacturing business. For this reason, it is of great importance to research product service system. The purpose of this paper is to research on the key problem of integrated product service system (IPSS) design. Design/methodology/approach A value-oriented IPSS is developed, which is set up based on “requirements-functions-processes-structures” mapping model to give full consideration to customer value and service functions. An extended product-service blueprint, which stems from the service blueprint, is developed to describe product behaviors, service deliver processes, stakeholders’ activities and supporting activities. An ontology-based design support system is proposed to improve design efficiency and help designers making better-informed decisions. A computer-aided prototype system has been developed, and an initial attempt has been made to demonstrate the role of IPSS in the aerospace industry. Findings Many traditional design methods cannot effectively address the objects and processes integration problem of products and services. Moreover, both product and service should be considered in IPSS design, and both of them extremely depend on designers’ own experience and knowledge. Thus, a broader range of knowledge is required to understand product-service system (PSS) design. Research limitations/implications This research provides a solid foundation for PSS C and promotes an effective means for PSS design. Originality/value A customer value-oriented IPSS is presented. Customer requirements are considered during the design phase of PSS as well as both product and service knowledge.

New Business Models

Product—service systems (PSSs) are often outlined as potential enablers of new business models for circular economy. However, not all business models based on product-service systems have superior circularity potential. This research demonstrates how the application of a previously developed business model configurator for circular economy can support the design and assessment of customer value, economic and resource decoupling potential for product-service system business models in practice. By applying action research in two Nordic manufacturing companies from the furniture sector, different business model concepts based on product-service systems were proposed and assessed. Results indicate positive uptake by companies regarding the usefulness of the obtained outcomes. This research identified two key findings about ‘product-service system business models for circular economy’: (i) their configuration should fulfil certain simultaneous conditions—i.e. superior customer value, economic growth, and resource decoupling potential—to contribute to circular economy; and (ii) they are often ‘niche solutions’, fulfilling specific needs and customer segments, and more likely to flourish with certain types/characteristic of products, segments or geographical locations. Lastly, a framework outlining the conditions and trade-offs for assessing the circularity potential of business models based on product-service systems is introduced as one of the key contributions.

The methods of capturing and transferring the customer value in a product service system (PSS) are studied to capture the customers’ intrinsic value requirements, grasp the importance level of requirement, and transform it into design elements to more reasonably allocate resources and develop products more in line with the customers’ needs and more competitive at a minimum cost. First, a hierarchical model of the customer value based on the means-end chain theory is constructed to analyze the customer value from the perspective of customer expectations. In the process of determining the importance priority of value elements, the cloud model is used to process the expert evaluation information, and the competitive correction factor and the Kano factor are used to modify the basic importance of the value elements. The customer value in the PSS is then transferred to the product and service performance domain by constructing the parallel house of quality embedded cloud model (PHOQ-ECM). In other words, the cloud model is used to process the group decision-making values with fuzziness and randomness to complete the correlation calculation of the parallel HOQ. The important priority of the performance characteristics is then obtained. Finally, the abovementioned methods are applied to capture and transfer the customer value of a shearer, and the results are compared with other studies. The results show that the hierarchical model of the customer value can more deeply capture the customer value. The cloud model solves the problem of group decision-making with fuzziness and randomness. The competition correction factor and the Kano factor improve the accuracy of the importance priority of the value elements. PHOQ-ECM achieves the transfer and distribution of the customer value to two different objects of product and service and improves the accuracy of the performance characteristics importance priority. The method feasibility and validity are verified through the abovementioned analysis. Consequently, the method can effectively guide the PSS design.

Sustainability Concept

Increasing awareness of the importance of services has given rise to the concept of product-service system where goods and services are sold as an integrated package to customers. On the other hand, the emerging sustainability concept has escalated the demand for sustainability for industries. Consequently, it is necessary to build strategies that lead the company to achieve sustainability goals while keeping competitiveness. Drawing on the necessity service and sustainability concept in the quality improvement of the product-service system, this study aims to develop a systematic design tool by filling the gap to the previous studies. We used Quality Function Deployment (QFD) approach by considering customer requirements (VoC) and stakeholder requirements (VoSt), instead of VoC only, based on the service and sustainability dimensions. We refer to the proposed QFD approach as QFDSPS. We introduce service productivity index (SPI) to measure the performance of the system. Thus, in the proposed methodology, the strategies for quality improvement were defined as subject to VoC, VoSt, and SPI. The methodology was implemented in a Javanese restaurant which meets the characteristics of a product-service system. The result shows that the proposed method can be implemented. The implications due to the implementation of the method are also discussed.

AbstractPrototypes are an established tool for rapidly increasing learning, communication and decision making rationale for design projects. The proven success has spawned a litany of approaches and methods for building and planning the efficient planning and construction of prototypes. Translating these methods into simple usable tools to assist novice designers has generated broadly applicable canvases to support prototyping across the design process. Product Service System design has similarly introduced prototyping methods and tools into the process. Presently there is a lack of support for generating early phase tangible prototypes for functional PSS design aimed at more radically innovative solutions instead of currently dominant traditional products with traditional add-on services. This work explores the viability of utilizing existing prototyping support tools in the context of early PSS design through workshops with student designers and practitioners. The data from these workshops illuminates the alignments and misalignment gaps presented as guidelines to enable better support for early PSS designers.
