J-MADeM, a market-based model for complex decision problems
Francisco Grimaldo, Miguel Lozano, Fernando Barber · Logic Journal of IGPL · 2010
This article presents J-MADeM, a multi-modal decision making mechanism to provide agents in a Multi-Agent System (MAS) with a market-based model for complex decision problems. The model is basically based on a set of utility functions, expressing the preferences of the agents for a specific problem, and a one-round sealed-bid combinatorial auction model as the procedure used to choose among different solutions. Thus, coordinated behaviours based on task/object passing can be evaluated to finally obtain acceptable allocations within a synthetic society. J-MADeM is able to simulate different kinds of societies (e.g. elitist, utilitarian, etc.), as well as social attitudes of their members (e.g. egoism, altruism, reciprocity, etc.). To evaluate J-MADeM, we analyse two problems: (i) the Gold Miners problem, where a new multi-agent organization is proposed to better adapt to different gold distributions; and (ii) a virtual university bar simulation, as an example of complex environment to verify the quality of the social behaviours achieved.
