@article{5679, abstract = {{Cloud computing promises the flexible delivery of computing services in a pay-as-you-go manner. It allows customers to easily scale their infrastructure and save on the overall cost of operation. However Cloud service offerings can only thrive if customers are satisfied with service performance. Allow-ing instantaneous access and flexible scaling while maintaining the service levels and offering competitive prices poses a significant challenge to Cloud Computing providers. Furthermore services will remain available in the long run only if this business generates a stable revenue stream. To address these challenges we introduce novel policy-based service admission control mod-els that aim at maximizing the revenue of Cloud providers while taking in-formational uncertainty regarding resource requirements into account. Our evaluation shows that policy-based approaches statistically significantly out-perform first come first serve approaches, which are still state of the art. Furthermore the results give insights in how and to what extent uncertainty has a negative impact on revenue.}}, author = {{Püschel, Tim and Schryen, Guido and Hristova, Diana and Neumann, Dirk}}, journal = {{European Journal of Operational Research}}, keywords = {{admission control, informational uncertainty, revenue management, cloud computing}}, number = {{2}}, pages = {{637--647}}, publisher = {{Elsevier}}, title = {{{Revenue Management for Cloud Computing Providers: Decision Models for Service Admission Control under Non-probabilistic Uncertainty}}}, volume = {{244}}, year = {{2015}}, } @article{5701, abstract = {{Purpose – The purpose of this paper is to craft a future research agenda to advance smart service research and practice. Smart services are delivered to or via intelligent objects that feature awareness and connectivity. For service researchers and managers, one of the most fascinating aspects of smart service provision is that the connected object is able to sense its own condition and its surroundings and thus allows for real-time data collection, continuous communication and interactive feedback. Design/methodology/approach – This article is based on discussions in the workshop on “Fresh perspectives on technology in service” at the International Network of Service Researchers on September 26, 2014 at CTF, Karlstad, Sweden. The paper summarizes the discussion on smart services, adds an extensive literature review, provides examples from business practice and develops a structured approach to new research avenues. Findings – We propose that smart services vary on their individual level of autonomous decision-making, visibility and embeddedness in objects and customer lives. Based on a discussion of these characteristics, we identify research avenues regarding the perception and nature of smart services, the adoption of smart services, the innovation through smart services as well as regarding the development of new business models. Originality/value – Smart services is a new emerging topic in service marketing research, their implications on organizations, customers and the service landscape have not been fully explored. We provide a fresh perspective on service research by characterizing relevant aspects of smart service that will stimulate fruitful future research and advance the understanding and practice of smart services.}}, author = {{Wünderlich, Nancy and Heinonen, Kristina and Ostrom, Amy L and Patricio, Lia and Sousa, Rui and Voss, Chris and Lemmink, Jos}}, journal = {{Journal of Services Marketing}}, keywords = {{Connected services, Intelligent object, New service type, Smart services}}, number = {{6/7}}, pages = {{442--447}}, publisher = {{Emerald Group Publishing Limited}}, title = {{{Futurizing” Smart Service: Implications for Service Researchers and Managers.}}}, volume = {{29}}, year = {{2015}}, } @article{5703, abstract = {{Purpose – The purpose of this paper is to encourage the reader to think differently about service-related issues and to strive to conduct service research that makes a transformational impact on individuals, organizations and society. The authors suggest that service researchers are in an excellent position to develop research that matters by making stronger connections with theory and elevating purely applied research to research that is higher in both practical relevance and methodological rigor. Design/methodology/approach – This paper takes a conceptual approach, connecting pertinent literature with new ideas highlighted in this special issue. Findings – This paper proposes that service researchers look beyond traditional service applications, take a multi-disciplinary approach to problem-solving and make greater strides towards connecting theory and practice. The authors propose a Model of Rigorous and Relevant Research, and call for fresh thinking across a wide range of research areas, including enhancing the customer experience, crafting innovation, integrating technology and measuring service outcomes.

Especially technology-based self-service channels have found their way into the 21st century service economy. While research embraces these channels for their cost-efficiency, it has not examined whether a shift from personal to self-service affects customer–firm relationships. Drawing from the service-dominant logic and its central concept of value-in-context, we discuss customers’ value creation in self-service and personal service channels and examine the long-term impact of these channels on customer retention. Using longitudinal customer data, we investigate how the ratio of self-service versus personal service use influences customer defection over time. Our findings suggest that the ratio of self-service to personal service used affects customer defection in a U-shaped manner, with intermediate levels of both self-service and personal service use being associated with the lowest likelihood of defection. We also find that this effect mitigates over time. We conclude that firms should not shift customers toward self-service channels completely, especially not at the beginning of a relationship. Our study underlines the importance of understanding when and how self-service technologies create valuable customer experiences and stresses the notion of actively managing customers’ cocreation of value. }}, author = {{Scherer, Anne and Wünderlich, Nancy and Von Wangenheim, Florian}}, issn = {{0276-7783.}}, journal = {{MIS Quarterly}}, keywords = {{customer defection, customer retention, e-service, longitudinal, Self-service, value-in-context}}, number = {{1}}, pages = {{177--200}}, publisher = {{MIS RC}}, title = {{{The Value of Self-Service: Long-Term Effects of Technology-Based Self-Service Usage on Customer Retention.}}}, volume = {{39}}, year = {{2015}}, } @article{5705, abstract = {{Despite the growing literature on loyalty program (LP) research, many questions remain underexplored.
