We have conducted an agent-based simulation of chain bankruptcy. The propagation of credit risk on a network, i.e., chain bankruptcy, is the key to understanding largesized bankruptcies. In our model, decrease of revenue by the loss of accounts payable is modeled by an interaction term, and bankruptcy is defined as a capital deficit. Model parameters were estimated using financial data for 1,07...

This paper describes formal architectural models for three types of service systems: static service system, dynamic service system and mobile service system. The system architectures are agent based. For each model, we investigate the properties and give the case study.

In this article we study the impact of the negotiation environment on the performance of several intra-team strategies (team dynamics) for agent-based negotiation teams that negotiate with an opponent. An agent-based negotiation team is a group of agents that joins together as a party because they share common interests in the negotiation at hand. It is experimentally shown how negotiation envi...

We provide a generaI anaIyticaI framework for empiricaIIy informed agent-based simuIations. That this methodoIogy provides present-day agent-based modeIs with a sound and proper insight as to the behavior of sociaI agents — an insight that statisticaI data often faII short of providing at Ieast at a micro IeveI and for hidden and sensitive popuIations. In the other direction, simuIations can pr...

We survey the relationships between evolution, individual learning and social transmission within well-mixed and structured environments. With a novel individual-based simulation, we determine the regimes under which each mode of learning dominates, in terms of the environment’s relative complexity and its rate of change. We show that social learning can give rise to a particularly potent form ...

Contemporary working environments are increasingly complex, volatile and physically distributed. Coordinating work in such environments is therefore becoming a major challenge as the traditional focus on efficient schedules is shifting to include other factors such as rapid reaction to market changes. This paper argues that effective coordination support should be based on a two-level coordinat...

1 We investigate the policies of (1) restricting social influence and (2) imposing curfews upon interacting citizens in a community. We compare their effects on the social order and the emerging levels of civil violence. We develop an agent-based model that is used to simulate a community of citizens and the police force that guards it. We find that restricting social influence pacifies rebelli...
