Creating a cost-effective large-scale multi-tier Enterprise service requires judicious selection and configuration of infrastructure elements and mechanisms. The minimum cost solution that satisfies business requirements for service availability and performance should be identified. Emerging self-managed computing utility environments demand an automated solution to this problem. This solution ...

system, such as a service robot, requires identifying and fulfilling many interdependent requirements. As the leader of an interdisciplinary team that designed and implemented a social robot and its service, I used human-centered and service design approaches to address this challenge. This is one of the first such design cases for a social robot service [1]. Two products of this study, a servi...

Companies developing physical products are challenged to find solutions through services as a means of innovative value-added solutions to support customer's needs. Designing integrated product and service systems to increase customer satisfaction requires the ability of companies to use knowledge in a more efficient way. However, the knowledge representation of product-service systems (PSS) re...

This study reports on the issue of consumer-led design ideas in service innovations. The research is conducted through a “service science” lens, which treats consumers, providers, and technologies as parts of a service system wherein their interaction results in potentially mutual benefits. However, do consumers want to provide input into the design of services, can their ideas be valuable, and...

The conventional methods of information system analysis and design are not based on service-oriented paradigm that facilitates control of business process continuity and integrity. Service-oriented representations are quite comprehensible for business experts as well as system designers. It is reasonable to conceptualize a business process in terms of service-oriented events, before the support...

The knowledge reuse and fusion/transformation system (KRAFT) is research prototype software for combining and transforming constraint-based knowledge. It is being developed in collaboration with BT by three UK universities — Aberdeen, Cardiff and Liverpool. The KRAFT system is designed to help its users to locate relevant data and constraint knowledge held in distributed heterogeneous data and ...

The Internet is an open space where a great number of computer systems are connected. Since many services are provided through the Internet, malicious users can easily intrude on any of those systems by using the vulnerabilities of the Internet. Although Intrusion Detection and Prevention System (IDPS) can be used to defend against such malicious activities, it is not always possible to complet...

The introduction of self-adaptation and self-management techniques in a service-oriented system can allow to meet in a changing environment the levels of service formally defined with the system users in a Service Level Agreement (SLA). However, a self-adaptive SOA system has to be carefully designed in order not to compromise the system scalability and availability. In this paper we present th...

This paper presents a metamodel that addresses service system design and innovation by traversing and integrating three essential layers, service activities, service systems, and value constellations. The metamodel's approach to service systems as service-in-operation is an alternative to another currently used approach that views service systems as systems of economic exchange. The metamodel a...
