Social Formation of Negotiation Space and Groups for Non-Isolated Multilateral Negotiations

Schröter K., Urbig D., Hans N.

Fundamenta Informaticae

2005

Vol. 67, nr 1-3

187--201

A mechanism is presented that allows agents in multiagent systems with private knowledge about resource endowments to establish negotiation groups with commonly known negotiation spaces. This is done by exchanging information. Specific agents that are provided by the system mediate the communication and take over some very complex calculations. The negotiating agents reveal only information to the mediators that they consider relevant for their own objectives or for the current negotiation. A broadcast of all the agents' private knowledge is not required. We label this interactive mechanism social formation of negotiation spaces and groups. Furthermore we drop the often-made assumption of isolated negotiations. Our agents remember other agents that have contributed to reach a beneficial agreement. These agents are assumed to have credits. In later negotiations our agents will be more generous towards agents with credits. The applied credit mechanism does not require that all agents participate nor does it require that other agents are aware of this mechanism. We conclude this report with hypotheses that will be evaluated by simulations.

TBase2 - a web-based electronic patient record

Schröter K., Lindemann-v.Trzebiatowski G., Fritsche L.

Fundamenta Informaticae

2000

Vol. 43, Nr 1-4

343-353

Fast and easy access to all relevant data is of most importance in medical diagnostics and therapy. Electronic patient records can fulfil these requirements much better than common paper-based records. This article describes the TBase2 system, an example of such an electronic patient record. It was developed in close cooperation with the Department of Nephrology at the university hospital Charité in Berlin. Due to its flexibility TBase2 can easily be adapted to the demands of other departments. Beside supporting the daily care for patients, TBase2 also gathers detailed data of high validity ideally suited for medical research.
