Abstract: | To enhance believability of virtual agents, this paper presents an agent-based modelling approach for decision making, which
integrates rational reasoning based on means-end analysis with personal psychological and biological aspects. The agent model
developed is a combination of a BDI-model and a utility-based decision model in the context of specific desires and beliefs.
The approach is illustrated by addressing the behaviour of violent criminals, thereby creating a model for virtual criminals.
Within a number of simulation experiments, the model has been tested in the context of a street robbery scenario. In addition,
a user study has been performed, which confirms the fact that the model enhances believability of virtual agents. |
