- Grid Computing in Small and Medium-Sized Enterprises: An Exploratory Study of Corporate Attitudes towards Economic and Security-Related Issues (2008)
- As Grid computing commenced in the scientific sector, it slowly enters the commercial environment. Although it proposes interesting features for horizontal integration of hardware and resource sharing, businesses slowly implement Intragrids in their companies. Open Grid markets are yet not deployed.
- 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.
- Theoretical and Computation Basis for CATNETS - Annual Report Year 3 (2007)
- In this document the developments in defining the computational and theoretical framework for economical resource allocation are described. Accordingly the formal specification of the market mechanisms, bidding strategies of the involved agents and the integration of the market mechanisms into the simulator were refined.
- Simulator Development - Annual Report Year 3 (2007)
- This document describes the progress of the simulator development with in the third year of the CATNETS project. The refinement of the simulator as well as a detailed guide to conducting simulations is presented.
- CATNETS Final Activity Report (2007)
- This paper presents the final activity report of the CATNETS project. It summarizes the project objectives, the contractors involved, the work performed and the final results. A description of the dissemination activities concludes the report.
- A Theoretical and Computational Basis for CATNETS (2006)
- The main content of this report is the identification and definition of market mechanisms for Application Layer Networks (ALNs). On basis of the structured Market Engineering process, the work comprises the identification of requirements which adequate market mechanisms for ALNs have to fulfill. Subsequently, two mechanisms for each, the centralized and the decentralized case are described in this document. These build the theoretical foundation for the work within the following two years of the CATNETS project.
- Environmental Analysis for Application Layer Networks (2005)
- Die zunehmende Vernetzung von Rechners über das Internet lies die Vision von Application Layer Netzwerken aufkommen. Sie umfassen Overlay Netzwerke wie beispielsweise Peer-to-Peer Netzwerke und Grid Infrastrukturen unter Verwendung des TCP/IP Protokolls. Ihre gemeinsame Eigenschaft ist die redundante, verteilte Bereitstellung und der Zugang zu Daten-, Rechen- und Anwendungsdiensten, während sie die Heterogenität der Infrastruktur vor dem Nutzer verbergen. In dieser Arbeit werden die Anforderungen, die diese Netzwerke an ökonomische Allokationsmechanismen stellen, untersucht. Die Analyse erfolgt anhand eines Marktanalyseprozesses für einen zentralen Auktionsmechanismus und einen katallaktischen Markt.
- Multiple Criteria Decision Making in Application Layer Networks (2008)
- This work is concerned with the conduct of MCDM by intelligent agents trading commodities in ALNs. These agents consider trustworthiness in their course of negotiation and select offers with respect to product price and seller reputation.
- A Scalability Analysis of Grid allocation Mechanisms (2008)
- This article examines the broker´s behavior with regard to a varying number of participating nodes and shows that incremental losses have to be accepted in central resource allocation when introducing new nodes.
- 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.
