Tool for simulating reputation management algorithms

We focus on the trust relationships between the agents¿ interactions. Agents make a trust decision before interacting, and this decision among other factors is based on an estimation of another agent¿s reputation. A reputation management system collects and analyzes interactions experience between agents. We suggest evaluation criteria for a trust or reputation management systems¿ evaluation. We implement a generic tool which can plug in a trust or reputation management algorithm and simulate the behaviour of the multiagent system where every agent follows the same algorithm. We illustrate the tool¿s support for some of the suggested evaluation criteria. We provide some recommendations for further development of the generic tool for evaluating and comparing the above-mentioned behaviour characteristics of different trust and reputation management algorithms.
