Trust Model of Privacy-Concerned, Emotionally Aware Agents in a Cooperative Logistics Problem

In this paper, we propose a trust model to be used in a hypothetical mixed environment where humans and unmanned vehicles cooperate. We address the inclusion of emotions inside a trust model in a coherent way to investigate the practical approaches to current psychological theories. The most innovative contribution of this work is the elucidation of how privacy issues play a role in the cooperation decisions of the emotional trust model. Both emotions and trust were cognitively modeled and managed with the beliefs, desires and intentions (BDI) paradigm in autonomous agents implemented in GAML (the programming language of the GAMA agent platform), that communicate using the IEEE FIPA standard. The trusting behavior of these emotional agents was tested in a cooperative logistics problem wherein agents have to move objects to destinations and some of the objects and places are associated with privacy issues. Simulations of the logistic problem show how emotions and trust contribute to improving the performance of agents in terms of both time savings and privacy protection. ; This work was funded by public research projects of the Spanish Ministry of Science and Innovation (CACTUS) (reference PID2020-118249RB-C22) and the Spanish Ministry of Economy and Competitiveness (MINECO) (reference TEC2017-88048-C2-2-R).
