Product-service systems (PSS), which create value by integrating physical products and services, have received much attention as a promising option to increase manufacturers’ revenue and reduce environmental impact. The process of designing a PSS requires collaboration among various experts who use domain-specific knowledge. Therefore, several researches have been investigated for developing design tools tailored to their expertise. However, while the specialization of design tools can be useful for experts, it hinders companies from ensuring the integrity of design information in different design elements. This results in the failure in achieving expected benefits. To address these issues, this study applies the concept of interoperability to PSS design to integrate design information from different domains. In particular, ontological descriptions is adopted to achieve semantic interoperability in different design elements. The application of the proposed ontology to a lecture on PSS design highlights that the proposed method is effective for integrating information on PSS design elements and those between value creation and capture.

For manufacturers, developing product–service systems (PSSs) is getting more important because of the trends of servitisation and creating social value. A PSS is a social system where multiple actors mutually provide products and services. A PSS design, therefore, must take into account various actors as customers. However, existing methods provide an insufficient solution as to how various customers should be handled in an analysis to identify and accommodate various customer preferences and requirements. To tackle this issue, this article proposes a new method of identifying customers’ orientations and requirements for PSS design. The proposed method employs a combination of topic analysis, persona and scenario approaches. The effectiveness of the method is demonstrated with its application to an urban development case. Through the demonstration, its practical benefits are concluded as follows: consistent and logical results of requirement analysis and insights into a new market for manufacturers.

Recently, the viewpoint of service has become widespread. In learning domains, service providers have been required to adopt the viewpoint and to provide values co-created by teachers and learners. However, production by a service provider means the generation of potential value, whereas usage by a service receiver implies the generation of real value. That is, a receiver creates value independent of the value generated by a provider. Indeed, value co-creation takes place in a joint sphere where providers and customers interact with each other. Thus, service providers must attempt to generate the potential value through service design and play a role of co-producer of the real value in the interactions between the providers and the receivers. In the current study, we developed an ontology to share the knowledge on value co-creation and the information related to the interactions between the providers and the receivers. In concrete terms, we proposed ontological descriptions of receiver states for sharing knowledge in learning service design, and conceptualized elements of consensus building and value co-creation, according to the conceptual model of value co-creation proposed in a previous study. In addition, concepts pertaining to academic emotions are also described to represent contents of consensus building. Then, we demonstrated instances of a consensus building, which is extracted from conversations during counseling by a teacher (mentor) and a learner. As a result, we obtained a metamodel for co-design processes in the learning service design, and a conceptual framework of the knowledge sharing on learning states including academic emotions by the ontological descriptions.

This study focuses on how to manage and utilise design knowledge in the conceptual design of product-service systems (PSSs). PSS is a business concept that manufacturing firms can use to enhance the value of their products. In order to design an effective PSS, it is important to search for value proposition opportunities throughout the entire product life cycle and offer appropriate services to customers at each opportunity. Because both products and services are included in the design space, PSS designers need to use a broader range of knowledge than that required in product design. Against such background, this article proposes a framework for managing and utilising PSS design knowledge to support idea generation in PSS design. The effectiveness of the framework is demonstrated by its application on an example of PSS design.

Focusing on the importance of considering value-in-context, this research aims to formalize how the concept of context should be handled in Product-Service Systems (PSS) design. In PSS design, it is important to combine products and services appropriately based on customer requirements. For the requirements analysis, specific situations in product use should be clarified considering customer context. However, there is no method to extract elements of customer context in existing PSS design methodologies. This paper proposes a framework which classifies viewpoints for extracting the elements of context. Based on the framework, a context-based requirements analysis process is also proposed.

Achieving learning objectives is considered as a value in use for higher education service. To achieve learning objectives, a teacher needs to grasp a learning state at each time point and then determine a target state that should be achieved by the next time point. With regard to the target state, the teacher also needs to achieve consensus with the learner. This study aims to support teachers in grasping the learning state and achieving consensus with the learner. To that end, we propose a model to represent changes in the learning state and the relationship between learning state and learning and instructional events.

One of the major features of product-service systems (PSS) design is a variety of design elements. This makes its design process complex and obscure. This study aims to develop a method for analysing how the design process influences the features of design solutions in the conceptual design of PSS. In this study, protocol analysis is applied to plural PSS design sessions. Simultaneously, their design solutions are evaluated relatively based on several aspects. Their design processes are analysed in connection with the above evaluation results. The findings obtained by using the proposed method will contribute to creating practical design guidelines for superior PSS development. (C) 2015 CIRP.

© 2014 by the author. A method for public service design, which enables designers to realize high-value added service design by considering plural different customer groups in parallel, is proposed. In General, service designs focus on specific customers. However, because of the diversity of customer requirements, it is difficult to design a public service that addresses the requirements of all customers. To achieve higher customer satisfaction, it is imperative to summarize the requirements of various customers and design a service by considering customers belonging to different categories. In this article, we propose a method that enables highly public service development by considering groups of various customers and minimizing customer dissatisfaction by adopting a group-decision-making approach. As a consequence, improvement of effectiveness of highly public service development can be expected.

The range and intention of Product-Service System (PSS) design are quite different from the traditional product-oriented design. Therefore, designers and design organizations in the future must have new capabilities and competencies to realize an effective PSS design. In this study, the authors develop an educational business game for accustoming users to the philosophy of PSS and changing their mindset. Business games have the advantage of effective and enjoyable learning through strategic thinking in a simulated business environment. This paper presents the latest structure of the developed game and types of strategic thinking of players in the game. The effectiveness of this game is demonstrated by the application in several workshops. (C) 2014 Elsevier B.V.

Product-Service Systems (PSSs) are regarded as an attractive business concept for manufacturing industries to increase their competitiveness. To design PSSs, it is important to have points of view different from those of product design. To teach such new viewpoints, the authors have developed a business game named "EDIPS." However, the learning effects of this game have not been analyzed sufficiently. To analyze the learning effects, this study first organizes the earning contents of the game. By using the organized learning contents as criteria, the learning effects can be analyzed by using results of pre- and post-tests for learners.

Demand response (DR), which controls electric usage of customers when electric system reliability is jeopardised, attracts much societal attention. To realise a pragmatic DR, aggregators have to make well-customised requests for power saving to keep each customer comfortable in energy use. An engineering method is proposed here to design a DR aggregation service from the viewpoint of various customers' comfort. The idea is to use an optimum resource allocation method that can provide quantitative information on how much electric power should be saved by each customer. The application validated the effectiveness of the proposed method. (C) 2014 CIRP.

A Product-Service System (PSS) includes numerous human interactions that are critical factors for improving customer satisfaction. PSS providers, therefore, have to organise appropriate human resources from the viewpoint of customer requirements. This paper proposes an engineering method to select appropriate human resources for the PSS design. Specifically, a function formulated by the neural network is proposed to predict customer satisfaction realised by each human resource so that each human resource can be prioritised in terms of customer satisfaction. The application used in this study validated the prediction accuracy of the proposed function as well as the effectiveness for allocating human resources in PSS design. (c) 2013 CIRP.

Product-Service Systems (PSS) are regarded as a new business concept for manufacturing firms to enhance the value of their products and build up strong relationships with their customers. Since both tangible products and intangible services are included in design object, a design solution of PSS has various alternatives especially in conceptual design phase. PSS design therefore requires a broader range of knowledge to generate several ideas for its design solution.
In this paper, for the purpose of supporting idea generation in PSS conceptual design phase, a knowledge management framework is proposed. The basic idea of the proposed method is managing and providing knowledge collected from PSS cases. The proposed knowledge management framework is defined by reference with the three design models of PSS: life cycle model, product-service function model, and actor network model. The effectiveness of the proposed method is presented on the basis of the application to an example: PSS using agricultural machinery in a developing country.

Compared to product design, a broader range of knowledge is required to Product-Service System (PSS) design, since both products and services are included in its design space. In this paper, a method for knowledge-based PSS design support is proposed. The proposed method is on the basis of the research on Japanese Service Engineering, which provides design methodology of the integrated provision of products and services. In addition, a prototype of computer-aided design (CAD) system to realize knowledge-based PSS design support is developed. The method and system support the acquisition of new PSS design solutions by integrating knowledge accumulated in a knowledge base. The developed system was applied to a design of an actual service: an accommodation service in Japan. The application result showed that the developed system was useful to support a design of the integrated provision of products and services. (C) 2012 Elsevier B.V. All rights reserved.

In service engineering, a service is represented as a functional structure that satisfies customer requirements. Specific entities and their activities are associated with a functional structure as a way to accomplish a goal. In this phase, it is important for service designers to have broad knowledge, since entities that construct a service include both human and physical products. Therefore, the extent of the designer's knowledge is the key to the enhancement of design solutions. However, few tools to support designers in the embodiment phase have been proposed. In this paper, for the purpose of constructing a function embodiment knowledge base in service design, the representational form of knowledge is proposed, and a prototype system of function embodiment knowledge base is established. Then function embodiment knowledge is collected from multiple service cases using the prototype system, and the effectiveness of knowledge base is discussed.

This paper proposes methods to support PSS conceptual design. Especially, methods for supporting PSS ideas generation and evaluation are proposed. In the phase of PSS ideas generation, designers' acquisition of new design solutions is enhanced by case-based knowledge offering. The generated ideas, subsequently, are evaluated from the viewpoints of both customer satisfaction and resource constraints. In this phase, the PSS ideas are prioritized for the purpose of maximizing customer satisfaction under the constraints of resources. The effectiveness of the proposed methods is demonstrated by applying it to an example case. (c) 2012 The Authors. Published by Elsevier B.V.

In Service Engineering, a basic structure of a service that satisfies customer requirements is designed through phases of “development of functional structures” and “embodiment of functions.” In the phase of embodiment, it is important, for the purpose of enhancing the quality of a design solution, to acquire a lot of knowledge from other service cases. In Service Engineering, service functions are represented by “verb-noun approach” which may leads a different expression of the same functions, and this makes exploring entities that realize a function difficult. In this paper, to describe service functions with a unified representation, the “input-output approach” of functional modeling is introduced in service design, and service design knowledge base is constructed based on the input-output functions. The result of the verification shows that the proposed method is useful to unify service function representation and effective to manage service design knowledge in the embodiment phase.

The emerging digital technologies such as IoT and their negative effects to human well-being are becoming a hot topic for discussion. In parallel, transformative service research, which focuses on uplifting changes and improvements in the well-being of both individuals and communities, has been recognized as one of the most meaningful areas in service research. Inspired by these two trends related to human well-being, this study aims at constructing a well-being-oriented service design methodology that has been insufficiently investigated. As the first step to this end, the present paper reports the results of a systematic literature review on (1) how the concept of well-being has been recognized in service research, (2) how the well-being can be effected by services/service design, (3) what can be features of a well-being-oriented service/service design. Based on implications from the results, a conceptual model for well-being-oriented service design is hypothetically structured. In addition, a reflection on present service design methodology and an expected role of IoT-related technologies are discussed.

As a key driver for servitization in manufacturing industries, the concept of Product-Service System (PSS) has been attracting much attention. In the design of PSS, it is notable to focus on value-in-context. Value-in-context can be regarded as a way of thinking that the value of a product is determined by customers depending on their own context of using the product. A context is not stable from both of short- and long-term perspectives. For a sustainable value proposition, it is important to design and manage a transition of the PSS considering changes in the context. This study focuses on long-term changes in the context and aims to develop a design methodology of such PSS transition. This paper proposes a modelling method for integrated design of future vision and transition pathway. In addition, a design process using the proposed models is proposed.

Recently, view point of service has been widespread. In learning domains, service providers have been required to adopt it and to provide values co-created by teachers and learners. The value co-creation takes place in joint sphere where providers and customers make interaction, and the value is subjectively perceived by receivers (learners in learning service). That is, a mental state of leaner is one of possible value in the co-creation. The current study aims to develop a conceptual framework which describes mental states of learners for specifying values in the co-creation. As a result, we proposed ontological descriptions of learning event which consists of a teacher, a learner, learning materials, and a learning action by the learner. In concrete terms, we proposed ontological descriptions for receiver states in a learning activity, on the basis of a conceptual model of value co-creation. The ontological descriptions are useful for sharing knowledge on values perceived by learners to design learning services.

One of the important benefits of PSS is to enable providers to construct a long-term relationship with their customer by offering services throughout the life cycle of product. However, customer requirements for the PSS vary over time. Therefore, to realize ideal PSS which realize a long-term relationship with a customer, it is necessary to image a to-be PSS in the future and design a growth scenario towards the to-be PSS. This paper focuses on such growth scenario and proposes a modelling framework to design it logically. The proposed model represents state changes of product/service, provider, receiver, and environment. Also, dependences between each state change are manifeted. The usefulness of the model is demonstrated by application to an example case.

This paper proposes a framework to design service offering strategy in Product-Service Systems. In this paper, service offering strategy is defined as "improvement plans of service offerings in order to enhance entire value of the business system by transforming as-is into to-be." A service is produced by co-creations among multiple relevant stakeholders e.g. customers, employees, managers and partners; and they have various requirements. To enhance the entire value of the system, therefore, it is important to understand relations among requirements and then discuss improvement plans for the service offerings. The proposed framework consists of (1) common and collision requirement visualizer and (2) service offering strategy roadmap. The effectiveness of the framework is demonstrated and discussed based on the application to a taxi business for vulnerable road users.

In the design of a Product-Service System (PSS), it is important for designers to embrace the objective of amplifying the value of product by combining with services throughout its life cycle. For designers who have only learned traditional engineering, however, it is difficult to think in this manner spontaneously. In order to resolve this issue, the authors have developed an educational business game named EDIPS that enables designers to consider the value amplification by combination of products and services Moreover, the effectiveness of EDIPS has been verified by using questionnaire data obtained in several workshops. However, actual learning effects through the game-playing have not been evaluated in an objective way. This paper analyzes changes in participants' understanding before and after the game-playing and activity transition during the game-playing. On the basis of the results of analysis, the learning effect of EDIPS is evaluated and discussed.

Product-Service Systems (PSS) are regarded as a new business concept for manufacturing firms to enhance the value of their products and build up strong relationships with their customers. Since both tangible products and intangible services are included in design object, a design solution of PSS has various alternatives especially in conceptual design phase. PSS design therefore requires a broader range of knowledge to generate several ideas for its design solution. In this paper, for the purpose of supporting idea generation in PSS conceptual design phase, a knowledge management framework method is proposed. The basic idea of the proposed method is managing and providing knowledge collected from PSS cases. The proposed knowledge management framework is defined by reference with the analysis results of PSS design experiment. The effectiveness of the proposed method is presented on the basis of the application to an example: PSS using agricultural machinery in a developing country.

As society matures, services are becoming the major factor in economic growth. Compared with product design, it is more necessary for service design to utilize many kinds of knowledge. To develop an effective support system for service designers, it is important to comprehend what kinds of knowledge are used in the design process. In product design research, it is said that design knowledge can be divided into "design object knowledge" and "design process knowledge." The authors have already conducted service design experiment and then classified "service design object knowledge" by analyzing collected protocol data. In this paper, "service design process knowledge" is analyzed by focusing on the design cycle constructed by five steps of designers' intellectual process. In this analysis, service design object knowledge is associated with the design cycle observed in the protocol data. Based on the utilization purposes of design object knowledge, service design process knowledge is classified.

Product-Service System (PSS) is regarded as a new business concept for manufacturing firms to enhance the value of their products and build up strong relationships with their customers. To realize a sustainable business, it is important for them to make a business situation where each stakeholder involved receives values through the provision of PSS. Namely, the designers have to have a holistic view and consider the total value created within the system. This paper proposes a method to design PSS that have high value for each stakeholder. In this method, a PSS is designed through a "design cycle" composed of three phases such as: (1) modeling, (2) simulation, and (3) new scenario description. Since this design cycle includes a phase to simulate a PSS designed, a PSS is designed under the simultaneous consideration of values received by various stakeholders. The proposed method is applied to an example PSS case. The result of the application showed the proposed method is useful to design high value-added PSS from a holistic viewpoint.

In service design, a broad range of knowledge must be needed for service designers. In the actual service field, however, service design relies on the designers' own knowledge, experiences, and intuition. To tackle this issue, the authors have proposed the basic policy to establish the function embodiment knowledge base, in which sets of function and its realization structure (entities and delivery process) are collected. In this paper, the service design catalogue, which is used to provide the accumulated knowledge to a service designer, is proposed. Then, on the basis of this scheme, the service design support system is developed.
