A Logic of Agent Organizations

arXiv.org Artificial Intelligence

Organization concepts and models are increasingly being adopted for the design and specification of multi-agent systems. Agent organizations can be seen as mechanisms of social order, created to achieve global (or organizational) objectives by more or less autonomous agents. In order to develop a theory on the relation between organizational structures, organizational objectives and the actions of agents fulfilling roles in the organization a theoretical framework is needed to describe organizational structures and actions of (groups of) agents. Current logical formalisms focus on specific aspects of organizations (e.g. power, delegation, agent actions, or normative issues) but a framework that integrates and relates different aspects is missing. Given the amount of aspects involved and the subsequent complexity of a formalism encompassing them all, it is difficult to realize. In this paper, a first step is taken to solve this problem. We present a generic formal model that enables to specify and relate the main concepts of an organization (including, activity, structure, environment and others) so that organizations can be analyzed at a high level of abstraction. However, for some aspects we use a simplified model in order to avoid the complexity of combining many different types of (modal) operators.


Societal Challenges Need Social Agents

AAAI Conferences

Big societal challenges involve many interdependent parties at different levels of society that are all interacting and reacting to each other. Although agent based simulations can help to support the analysis of these problems, we argue that we need to develop a fundamental social framework for the agents in these simulations in order to get a grip on the underlying mechanisms at work. We show some scenarios where we applied some of the ideas and sketch the sociological foundation of the agents and an agent architecture that can be used for building agent based simulations for societal challenges.
