Abstract: In the present study, an object oriented approach and modeling framework is proposed for the construction of synthetic, computational models of social systems. The conventional approach to model and study social systems will be reviewed and outlined, indicating its limitations to deal with their associated complex turbulent phenomena. The proposed object oriented integrative modeling will be explained emphasizing its advantages compared to reductionist methods when dealing with complex systems. Finally, the main architecture of the UTOPIA computational modeling framework, an ongoing, development is shown and described.
