چکیده

We address long-term coalitions that are formed of both customer and vendor agents after evaluating their trust relationships with other agents in the system. We present a coalition formation mechanism designed at agent level and analyzed at both system and agent levels. Evaluation has been conducted to compare agent strategies (individual vs. social) and to analyze the system behavior under different circumstances. Our results show that the coalition formation mechanism is beneficial for both the system (it reaches an equilibrium state) and for the agents (their gains increase exponentially in time).

History Based Coalition Formation in Hedonic Context Using Trust

In this paper we address the problem of coalition formation in hedonic context. Our modelling tries to be as realistic as possible. In previous models, once an agent joins a coalition it would not be able to leave the coalition and join the new one; in this research we made it possible to leave a coalition but put some restrictions to control the behavior of agents. Leaving or staying of an age...

Using Information Security as a Facet of Trustworthiness for Self-Organizing Agents in Energy Coalition Formation Processes

Trustworthiness besides other decision making factors like technical or regulatory requirements can be one key aspect for the decision making in coalition formation processes with agents in the energy domain. In this paper the trustworthiness facet information security is used to describe the realized security measures and standards of the systems for coalising energy agents as one trust buildi...

Real-Time Satisficing Multiagent Coalition Formation

In a multiagent system where each agent has only an incomplete view of the world, optimal coalition formation is difficult. Coupling that with real-time and resource constraints often makes the rationalization process infeasible or costly. We propose a coalition formation approach that identifies and builds sub-optimal yet satisficing coalitions among agents to solve a problem detected in the e...

Threat Scenarios to evaluate Trustworthiness of Multi-agents in the Energy Data Management

Trustworthiness is a key aspect for coalition formation with agents in the energy domain. In this paper first results for developing a trust model for a multi-agent-based energy management system are given. First, the terms trust, reputation and trustworthiness are defined. After that an exemplary scenario of a trustworthy coalition formation of energy agents is described. The main result of th...
