The idea of this course is to approach complex systems in a practical way, that allows active learning.
Complex systems are networks made of a number of components that interact with each other, typically in a nonlinear fashion. Complex systems may arise and evolve through self-organization, such that they are neither completely regular nor completely random, permitting the development of emergent behavior at macroscopic scales. H. Sayama
Systems thinking (ST) is a holistic approach to analysis that focuses on the system as unity, taking into account a system’s parts, their interconnections, and the whole system’s evolution over time and over space. System thinking allows future leaders to see the big picture and understand and influence the consequences of their decisions. The core idea is to view the problem as a part of big interconnected system, so one can understand the system only after understanding its elements and their interconnections. ST can be applicable to every complex system, e.g. project management, economy, politics, society, and education, among many
Complexity science (CS) proposes the extension of ST paradigm, allowing to deal with rather complex than complicated systems. CS view on the complex system is to admit that complexity arises between deterministic and chaotic behavior and a full understanding of system evolution requires multiple models and simulations.
