In previous works [1,2,3], we presented the first phase of the MAS organization
modeling, developed using the organizational model MOISE+ [4,5], identifying the or-
ganizational roles of the San Jerónimo vegetable garden (in Spanish: Horta San Jerón-
imo - HSJ) and their routines, the social interactions, the regulative and constructive
norms.
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.
Due to the difficulty found in the modeling of the periodic routines that characterize
the behaviors of the different organizational roles identified in the HSJ social organi-
zation, as well as their normative aspects, we decided to explore more the JaCaMo
platform (http://jacamo.sourceforge.net/), which is a framework for Multiagent Pro-
gramming that combines three separate technologies, namely Jason (for programming
autonomous agents, Cartago (for programming environment artifacts) and MOISE (for
programming multiagent organizations).
However, we observed that the MOISE+ model lacks facilities for specifying rou-
tines. So, we decided to analyze another related tool, namely the MSPP (Modeling and
Simulation of Public Policies) framework[6,7], which allowed us to specify the period-
icity in role behaviors in the HSJ social organization.
Then, for the modeling of such kind of periodicity commonly observed in social
system, we found that a combination of tools can offer a suitable solution, namely, the
MOISE+ of JaCaMo platform and the MSPP framework. Although those tools sepa-
rately 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, such that the
norms are specified in the MSPP framework, which support periodicity, and the nor-
malized routines in the MOISE+ model.
The aim of this work is to present an analysis, through the modeling of the HSJ social
organization, of the results obtained with the application of the MOISE+ organizational
model [2] and the MSPP framework, pointing to the limitations found with respect to
the modeling of periodic normalized routines in a social system. Then, the proposed
combined solution is discussed.
The paper is organized as follows. Section 2 explain the social project of HSJ, pre-
senting some examples of our preliminary modeling of the HSJ social organization.
Section 3 presents the Jacamo Plataform and the MSPP framework, with a discussion
on their use for the modeling of periodic routines. In Section 4, we present the restric-
tions of Moise+ and how to solve them with the MSPP framework. Sections 5 presents
the conclusion and further works.
