Matchmaking for business processes based on conjunctive finite state automata

2005 , Wombacher, A. , Fankhauser, P. , Mahleko, B. , Neuhold, E.

Web services have a potential to enhance B2B e-commerce over the internet by allowing companies and organisations to publish their business processes on service directories where potential trading partners can find them. This can give rise to new business paradigms based on ad-hoc trading relations as companies, particularly small to medium scale, can cheaply and flexibly enter into fruitful contracts, e.g., through subcontracting from big companies. More business process support by the web service infrastructure is however needed before such a paradigm change can materialise. The current infrastructure does not provide sufficient support for searching and matching business processes. We believe that such a service is needed and will enable companies and organisations to establish ad-hoc business relations without relying on manually negotiated frame contracts like RosettaNet PIPs. This paper gives a formal semantics to business process matchmaking and an operational de scription for matchmaking. Copyright

Skalierbare Verarbeitung von XML mit Infonyte-DB

2002 , Tesch, T. , Fankhauser, P. , Weitzel, T.

Die zunehmende Durchdringung von IT-Architekturen mit XML führt zu immer größeren XML-Datenvolumina. Diese lassen sich mit den zur Verfügung stehenden XML-Werkzeugen nicht immer skalierbar verarbeiten. Das Produkt Infonyte-DB der Infonyte GmbH ist ein modularer XML-Kernel, der sehr ressourcenschonend große XML-Datenvolumina effizient verarbeiten kann

Arbitration Protocols for Competing Software Agents

2001 , Tesch, T. , Fankhauser, P. , Ouksel, A.M.

The exchange of goods and services between bargaining software agents requires new forms of brokering mechanisms which achieve consensus between conflicting pal-ties. Such mechanisms have to be designed in a way that they give rational self-interested agents no incentives for insincere behavior. We introduce an arbiter as third party that resolves conflicting bargaining situations between the agents. To achieve non-manipulative agent behavior, we investigate three arbitration protocols that avoid different forms of manipulations and show how each trades net efficiency for robustness against manipulations. We describe the applicability of the protocols in bilateral bargaining situations and, analyze their robustness against manipulations analytically and by simulations. We compare the protocols with Nash's arbitration(1) and the Groves-Clarke tax(2) and characterize situations in which our protocols are superior.
