Modeling Organizational Information System Architecture Using "Complex Networks" Concepts

Organizations live in a world where interdependence, self-organization and emergence are factors for agility, adaptability and flexibility plunged into networks. Software-based information systems go into a service oriented architecture direction and the same goes to Infrastructures where services are become structures available in networks. Inspired into empirical studies of networked systems such as Internet, social networks, and biological networks, researchers have in recent years developed a variety of techniques and models to help us structurally understand or predict the behavior of these systems. Those findings are characterized by been supported on the "complex networks" concepts. On this PhD research we present the use of the concepts of complex networks from physics to develop organizational information system architectural models, as requirements modeling technique. The research is about the structure and function of networks and its use for modeling organizational information systems architectures by using a combination of empirical methods, analysis, and computer simulations.
