Voting policies that cope with unreliable agents

Collaboration plays a critical role when a team is striving for goals that are difficult to achieve by an individual. In previous work, we defined the ETAPP (Environment-TaskAgents-Policy-Protocol) framework, which describes the collaboration of a team of agents. According to this framework, team members propose agents to perform a task, and the team applies a voting policy to choose an agent for the task. In this paper, we expand on three parameters of this framework. We model team members that have variable proposal making attitudes, and team members whose performance exhibits different levels of stability. We then consider two new voting policies for group decision-making, and use a simulation-based evaluation to investigate the interaction between the different types of team members and the voting policies. Our results show that our previous optimistic voting policy, which chooses the agent that seems to have the best performance, yields an unstable task performance for teams w...
