Modeling Role Interactions in a Social Organization for the Simulation of the Social Production and Management of Urban Ecosystems: The Case of San Jerónimo Vegetable Garden of Seville, Spain

This paper presents some preliminary results obtained in the modeling of a multiagent system for the simulation of the social production and management of a urban ecosystem, in particular, the project of the San Jerónimo Vegetable Garden of city of Seville, Spain. We introduce a study regarding the interactions between agent roles in this particular social organization. For that, we use Activity Diagrams of UML, which provide a clear visualization of the communication between agent roles and allow the identification of communication protocols used by the agents. Furthermore, we show an initial proposal for the encapsulation of those protocols in Cart Ago artifacts, presenting a more modular approach for agent communication in multiagent systems.

Analyzing the Problem of the Modeling of Periodic Normalized Behaviors in Multiagent-Based Simulation of Social Systems: The Case of the San Jerónimo Vegetable Garden of Seville, Spain

This paper presents some results obtained through the modeling of a multiagent system for the simulation of production and social management processes of an urban ecosystem: the San Jeronimo Vegetable Garden (HSJ) of Seville, Spain. The social organization of HSJ is based on the performance of periodic routines by the organizational roles, and also on periodic norms that regulates their behaviors. For the modeling this kind of periodicity, that are commonly observed in social system, we used a combination of tools to offer a suitable solution, as the MOISE+ (part of JaCaMo platform) and the MSPP (Modeling and Simulation of Public Policies) framework. Although those tools separately present limitations for the modeling of periodic actions and norms associated to the performance of those actions, they can be used in a combined way, where the norms are specified in the MSPP framework, which support periodicity, and the normalized routines in the MOISE+ model.

Exchanges of Services Based on Piaget's theory of Social Exchanges Using a BDI-Fuzzy Agent Model

Piagets theory of social exchanges has been used as the basis for the analysis of interactions in Multiagent Systems, allowing the modeling of interactions as services exchange processes between pairs of agents, followed by the evaluation of those services by the agents involved, producing the so-called social exchange values. The purpose of this work is to develop a BDI-Fuzzy agent model for the Jason platform, with abilities to assess qualitatively, subjectively the social exchanges values originated in the provision and in the receipt of non-economic services, based on Piagets theory of social exchanges. An application to the simulation of exchange processes in a social organization, namely, the urban vegetable garden San Jerónimo (Seville, Spain) is presented.

Simulating Reputation with Regulatory Policies: The Case of San Jerónimo Vegetable Garden, Seville, Spain

This paper presents a reputation model applied to a multi-agent system for simulating regulatory policies and reputation of the social organization of San Jeronimo Vegetable Garden, located in Seville, Spain. We have used BDI agents with fuzzy beliefs for the investment and satisfaction analysis of services, as well as a reputation model as a performance measure of their activities within the project.

Modeling Agent Periodic Routines in Agent-Based Social Simulation Using Colored Petri Nets

Periodic routines have been traditionally identified in Social Sciences as the essential component of social organizations that are persistent in time, with the temporal continuity of such routines constituting the foundation of the preservation of the social systems both between successive generations and between extant and immigrant populations. Open multiagent systems (MAS) with persistent social organizations are, thus, required to be organized around time-persistent periodic routines. In this paper we propose to make use of Coloured Petri Nets (CPN) for the specification of periodic routines that may characterize the social organization of MAS. In particular, the central notions of routine cut, selected routine cut, routine step, and routine step results, as well as the notion of satisfactory performance of a periodic routine, are defined, and illustrated through a detailed example. The notion of routine objective expectation and deviation are used for the analysis of routine performances.
