Resumen
El objetivo de esta tesis doctoral es construir un marco conceptual para los sistemas sociales utilizando el formalismo de especificación de sistemas de eventos discretos (DEVS) para modelar y simular propiedades, interacciones y procesos específicos de los sistemas sociales.
La introducción contiene una breve historia del campo del modelado y la simulación, presenta el concepto de ciencia, justifica el enfoque constructivista de los sistemas y presenta las preguntas de investigación, los objetivos y las contribuciones esperadas.
El segundo capítulo establece conceptos generales sobre los sistemas sociales, describe su composición, su estructura y su entorno, y explica su comportamiento. Esto es seguido por una discusión de los conceptos de emergencia, autoorganización y computación social.
El tercer capítulo presenta conceptos básicos sobre modelado y simulación, justifica el uso de modelos y compara enfoques de modelado simples y complejos. Luego, demuestra la simulación como una nueva frontera en la ciencia y establece el modelado y la simulación (M&S) como un campo unificado e independiente. Esto es seguido por una descripción de los diferentes formalismos de especificación del sistema y su relación con el manejo del tiempo. Finalmente, muestra DEVS y sus extensiones.
El cuarto capítulo presenta cómo OMG Systems Modeling Language (OMG SysMLTM) se utiliza para modelar sistemas sociales. Describe un nuevo enfoque de la taxonomía de SysML, muestra diagramas SysML relacionados con propósitos, explica diagramas SysML asociados con la estructura y presenta cómo usar diagramas SysML para representar el comportamiento de un sistema social.
El quinto capítulo describe la propuesta marco. Explica el papel de las teorías sociales en las plantillas computacionales, presenta el séxtuplo de modelos computacionales, propone un marco para el modelado y la simulación de sistemas sociales usando DEVS, y muestra un ejemplo del marco propuesto basado en el modelo básico de Agent_Zero.
The objective of this doctoral thesis is to build a conceptual framework for social systems using discrete event system specification (DEVS) formalism to model and simulate specific properties, interactions, and processes of social systems. The introduction contains a brief history of the field of modelling and simulation, introduces the concept of science, justifies the constructivist approach to systems, and presents the research questions, the objectives, and the expected contributions. The second chapter establishes general concepts about social systems, describes their composition, their structure, and their environment, and explains their behaviour. This is followed by a discussion of the concepts of emergence, self-organization, and social computations. The third chapter presents basic concepts about modelling and simulation, justifies the use of models, and compares simple and complex modelling approaches. Then, it demonstrates simulation as a new frontier in science and establishes modelling and simulation (M&S) as a unified and independent field. This is followed by a description of different system specification formalisms and their relationship with time handling. Finally, it depicts DEVS and its extensions. The fourth chapter introduces how OMG Systems Modelling Language (OMG SysMLTM) is used to model social systems. It describes a new approach to the taxonomy of SysML, shows SysML diagrams related to purposes, explains SysML diagrams associated with the structure, and presents how to use SysML diagrams for depicting the behaviour of a social system. The fifth chapter describes the framework proposal. It explains the role of social theories in computational templates, presents the sextuple of computational models, proposes a framework for the modelling and simulation of social systems using DEVS, and shows an example of the proposed framework based on basic Agent_Zero’s model.
