Global models

Best known of the systemic methods. The object of global methods is the world system, seen in the function of future development. They constitute one of the solutions proffered by science (mainly in the 1970s) to try to tackle the complexity of history in recent years. Some reasons for adopting global models are as follows: 1. The complexity of problems, because of the growing interrelationships of different areas. 2. The high level of social dynamics, due especially to scientific and technological developments (today we can add social and political) that have a strong impact on society.3. The need for analytical rigor in the analysis of complexity. Global models have used as a consequence: 1. The systemic approach. 2. Futures Studies methods. 3. Quantitative methods with utilization of mathematical models and computers as tools.
