      <title>The service-productivity learning cockpit – a business intelligence tool for service enterprises</title>
      <link>http://opus4.kobv.de/opus4-ubbayreuth/frontdoor/index/index/docId/957</link>
      <description>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.</description>

      <title>The BabelNEG System - A Protocol-generic Infrastructure for Electronic SLA Negotiations in the Internet of Services</title>
      <link>http://opus4.kobv.de/opus4-ubbayreuth/frontdoor/index/index/docId/770</link>
      <description>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.</description>

      <title>Reputation in Multi Agent Systems and the Incentives to Provide Feedback</title>
      <link>http://opus4.kobv.de/opus4-ubbayreuth/frontdoor/index/index/docId/525</link>
      <description>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.</description>

      <title>A Survey on Reputation Systems for Artificial Societies</title>
      <link>http://opus4.kobv.de/opus4-ubbayreuth/frontdoor/index/index/docId/503</link>
      <description>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.</description>

      <title>Market Acceptance of Cloud Computing - An Empirical Analysis of Market Structure, Price Models and Service Requirements</title>
      <link>http://opus4.kobv.de/opus4-ubbayreuth/frontdoor/index/index/docId/468</link>
      <description>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.</description>

      <title>A Policy Framework including Trust and Reputation in Grid Environments</title>
      <link>http://opus4.kobv.de/opus4-ubbayreuth/frontdoor/index/index/docId/394</link>
      <description>This paper examines the role of policies in different grid environments. A Grid technology becomes standardized and stable, various business models are envented and increasingly applied, and economic implications can be observed.Asymmetrically distributed information may allow for opportunistic behaviour of service providers or users who exploit the information gap between providers and consumers on the quality of services.</description>
