Abstract: In the aftermath of a large-scale disaster, agents' decisions range from individual (e.g., survival) to collective (e.g., victims' rescue or fire extinction) attitudes, thus shaping a 2-strata decision model. However, current decision-theoretic models are either purely individual or purely collective and find it difficult to deal with motivational attitudes. On the other hand, mental-state based models find it difficult to deal with uncertainty. We describe two hybrid decision models: 1) the collective 'versus' individual (CvI), which integrates both strata quantitative evaluation of decision making; 2) the CvI-JI which extends the CvI model, using the joint-intentions formulation of teamwork, to deal with collective mental-state motivational attitudes. Both models are evaluated from an experimental, case study-based, outlook that explores the tradeoff between cost reduction and loss of optimality while learning coordination skills in a partially observable stochastic domain.
