- Tagungsband zum Doctoral Consortium der WI 2013 (2013)
- Bereits seit Anfang der 1990er Jahre wird jungen Wissenschaftlern im Vorfeld der Tagung "Wirtschaftsinformatik" ein Doctoral Consortium als unterstützendes Forum angeboten. Diese Einrichtung wurde auch zur größten internationalen Konferenz der Wirtschaftsinformatik, der WI 2013 in Leipzig, fortgeführt. Dieser Band fasst die zum Vortrag ausgewählten Beiträge zusammen.
- The service-productivity learning cockpit – a business intelligence tool for service enterprises (2012)
- The paper describes the development of an agent-based simulation tool for hospital managers to manage their productivity of services, especially in the context of supporting services like patient transport logistics. The learning cockpit allows hospital managers to see how the change of inputs changes the overall perceived customer values of all stakeholders and therefore to get a visualization of the impacts their decisions cause. The paper introduces the general research domain service-productivity, followed by a description of the development steps of artefact creation. The learning cockpit is part of a research project called BELOUGA, which is funded by the German government.
- The BabelNEG System - A Protocol-generic Infrastructure for Electronic SLA Negotiations in the Internet of Services (2011)
- Visions of the next-generation Internet of Services are driven by digital resources traded on a global scope. For the resulting economic setting, automated on-line techniques for handling services and resources themselves, for advertising and discovering as well as for the on-the-fly negotiation of proper terms for their use are needed. Hence, a flexible infrastructure for the respective management of services and associated service level agreements is mandatory. This thesis presents the results of my dissertation project. They comprise a service infrastructure, able to support the structured discovery and protocol-generic negotiation of electronic service level agreements (SLAs) and thus services themselves.
- Tagungsband zum Doctoral Consortium der WI 2011 (2011)
- Since the early 1990es, young researchers participate in the doctoral consortium series, co-located with the "Wirtschaftsinformatik" conference. This volume contains the selected papers of 20 PhD candidates of the 2011 doctoral consortium in Zurich.
- Proceedings of the 12th European Agent Systems Summer School Student Session (2010)
- This volume contains the papers presented at the Student Session of the 12th European Agent Systems Summer School (EASSS) held on 25th of August 2010 at Ecole Nationale Superieure des Mines de Saint-Etienne, France. The Student Session, organised by students, is designed to encourage student interaction and feedback from the tutors. By providing the students with a conference-like setup, both in the presentation and in the review process, students have the opportunity to prepare their own submission, go through the selection process and present their work to each other and their interests to their fellow students as well as internationally leading experts in the agent field,both from the theoretical and the practical sector.
- Reputation in Multi Agent Systems and the Incentives to Provide Feedback (2009)
- The emergence of the Internet leads to a vast increase in the number of interactions between parties that are completely alien to each other. In general, such transactions are likely to be subject to fraud and cheating. If such systems use computerized rational agents to negotiate and execute transactions, mechanisms that lead to favorable outcomes for all parties instead of giving rise to defective behavior are necessary to make the system work: trust and reputation mechanisms. This paper examines different incentive mechanisms helping these trust and reputation mechanisms in eliciting users to report own experiences honestly.
- Proceedings of the 11th European Agent Systems Summer School Student Session (2009)
- This volume contains the papers presented at the Student Session of the 11th European Agent Systems Summer School (EASSS) held on 2nd of September 2009 at Educatorio della Providenza, Turin, Italy. The Student Session, organised by students, is designed to encourage student interaction and feedback from the tutors. By providing the students with a conference-like setup, both in the presentation and in the review process, students have the opportunity to prepare their own submission, go through the selection process and present their work to each other and their interests to their fellow students as well as internationally leading experts in the agent field, both from the theoretical and the practical sector.
- A Survey on Reputation Systems for Artificial Societies (2009)
- The Internet has caused a revolution in trading. Especially cheap items are now easy to buy and sell on the Internet. As a consequence, sellers nowadays offer a wide range of products on the web, creating an abundance of choice for consumers. Consumers have the opportunity to browse on different auction sites for the item they really want. Along with this success story, however, came the stories of people being cheated by fraudulent online sellers. These frauds cover a range from not delivering what has been promised, the overrating of a product´s condition, to deliberate acts of theft. They are a result of so-called asymmetric information. Trust and reputation mechanisms are intended to address this asymmetric information distribution. This article surveys the most common trust and reputation systems.
- Make-or-Buy im Cloud-Computing - Ein entscheidungsorientiertes Modell für den Bezug von Amazon Web Services (2009)
- Die Frage nach Eigenfertigung oder Fremdbezug von IT-Servicedienstleistungen ist häufiger Bestandteil unternehmerischer Entscheidungen. Neben bekannten Outsourcingvarianten wie z. B. Application-Service-Provisioning, steht neuerdings eine weitere Alternative zur Verfügung: Cloud-Computing. In dem vorliegenden Artikel wird die Problemstellung „Eigenerstellung oder Fremdbezug von Cloud-Computing-Services“ untersucht. Dabei wurde ein formaler Ansatz für die Make-or-Buy-Entscheidung entwickelt, dessen Verlässlichkeit durch die Anwendung auf realistische Szenarien gezeigt wird. Die Untersuchung zeigt auch, dass neben der in der Literatur verbreiteten Ansicht, die Wirtschaftlichkeit von Cloud-Computing-Services hänge vor allem von der übertragenen Datenmenge ab, sowohl der von den Autoren neu eingeführte Auslastungsgrad, welcher Schwankungen in der Auslastung der Rechenkapazität beschreibt, als auch die Menge an zu speichernden Daten eine wesentliche Rolle spielen. Diese Beobachtung ist auf Skalen- und Risiko-Pooling-Effekte zurückzuführen, wie sie seitens der Cloud-Computing-Anbieter ausgenutzt werden um ihre Kosten durch Fixkostendegression zu senken.
- Market Acceptance of Cloud Computing - An Empirical Analysis of Market Structure, Price Models and Service Requirements (2009)
- As an emerging technology and business paradigm, Cloud Computing embeds fairly large amount of unexplored fields, from technological definition to business models. While the market of Cloud Computing is expected to expand in the near future, few studies of the actual market acceptance of the Cloud Computing services are done. It may be interesting, especially for the Cloud Computing service providers, to know more about the preferences of transaction forms and price models from the users and potential users. From an academic research’s point of view, we want to know whether the development of Cloud Computing market can be explained or even predicted by certain theoretical frameworks.
