The decision of selecting the portfolio of services to be included in a service system and the issues that complicate this decision problem are discussed. A general portfolio decision making framework is presented and compared with the Microsoft Operations Framework (MOF) Business/IT Alignment Service Management Function (SMF).

Product–service systems (PSSs) have significant sustainability potential. However, limited knowledge is available on the choices to develop circular PSS solutions. The goal of this paper is to provide a circular innovation framework containing circular strategies to facilitate the decision-making in PSS circular innovation. A systematic literature review in combination with content analysis underpinned this research. The strategies were investigated in 45 PSS cases from the literature. A coding system was designed and employed to identify and organize the circular strategies and practices. The statistics techniques employed were frequency and co-occurrence analysis, which aimed to describe the synergies among strategies. The framework proposed contains twenty-one circular strategies. The practical perspective comprises the seventy-seven practices used for the operationalization of strategies. The framework can assist organizations in making strategic to tactical decisions when developing circular PSS solutions. The paper provides a panorama of the strategy applications among the PSS types. Finally, the research approach can be employed to continuously develop an understanding of the application of circular strategies in PSS and other fields.

This chapter shows a systems technologies framework to lead the approach to design information service system architecture standing on the systems concept. It also presents application examples for building smart public infrastructures. Moreover, it shows that a systems concept, autonomous decentralization, gives a consistent design approach for the reference architecture, the concrete architecture, and the implementation. The presented service system provides an autonomous process for a service receiver to get valued information changing the state of the receiver. The example of the service system provides, recursively, the information to see in smart public infrastructures (MIERUKA in Japanese) for rapid decision making among stakeholders in the business process.

Purpose – The purpose of this paper is to investigate the implications of the networked and open nature of the service business on performance measurement. The literature has acknowledged that the value of service is increasingly produced by service systems, but solutions for measuring the performance of a service system are still lacking. Design/methodology/approach – The paper constructs a conceptual framework for capturing performance of a service system by combining ideas from the service management and performance measurement literatures. This framework is then applied in two service systems, one from the public sector and one from the private sector. Two different service systems provide complementary views on the phenomenon of service system performance and call for distinctive measurement solutions. In both cases, interviews, series of workshops and an analysis of documentation of the prevailing measurement systems were conducted when applying the framework. Findings – The results indicate that the performance measurement of a service system necessitates measurement information from three perspectives: the performance of individual actors, the internal efficiency of a network and the customer-perceived performance of service operations. The paper provides empirical evidence about the design and implementation of performance measurement for a service system. It also provides some guidance to overcome the recognized measurement challenges that relate, for example, to the shared responsibilities, to integration of measurement data and to capturing customer-perceived impacts of services. Originality/value – The paper provides new understanding about performance measurement practice in a service system. It integrates service-dominant management philosophy into the long tradition of performance measurement, which concentrates excessively on organizational structures. Even though the common balanced performance measurement frameworks include the perspective of a customer, the application of the frameworks is easily side-tracked leading to sub-optimization when several organizations and customers participate in value creation. Practical implications – Empirical evidence illustrates the practical need for a new perspective on performance measurement of service systems. This can be achieved by shifting the unit of analysis from organizations to customer-perceived performance. The practical performance measurement systems need to balance with the aspects of effectiveness and outcomes of services, the efficiency of the production network and the performance of individual actors.

In the present work, the adjacency matrix, the energy and the Laplacian energy for a picture fuzzy graph/directed graph have been introduced along with their lower and the upper bounds. Further, in the selection problem of decision making, a methodology for the ranking of the available alternatives has been presented by utilizing the picture fuzzy graph and its energy/Laplacian energy. For the shake of demonstrating the implementation of the introduced methodology, the task of site selection for the hydropower plant has been carried out as an application. The originality of the introduced approach, comparative remarks, advantageous features and limitations have also been studied in contrast with intuitionistic fuzzy and Pythagorean fuzzy information.
