We consider the Markov and non-Markov processes in complex systems by the dynamical information Shannon entropy (DISE) method. The influence and important role of the two mutually dependent channels of entropy alternation (creation or generation of correlation) and anti-correlation (destroying...

The scaling of the probability distribution of the Sao Paulo Stock Exchange index is shown to be described by a Levy stable stochastic process for the modal region of the distribution. Data refer to daily records for the 30-year period 1968-1998. The truncated Levy process is characterized by a...

Although it is a relatively new subject discussed worldwide by economic researchers, the complexity paradigm invites us to make ample incursions in time in order to understand the substantial differences between the optics of standard economic theory and the holistic approach of the new economy....

Although the majority of researchers interested in ABM increasingly agree that the most natural way to program their models is to adopt OO practices, UML diagrams are still largely absent from their publications. In the last 15 years, the use of UML has risen constantly, to the point where UML...

This paper presents two applications of the multi-scale integrated analysis of societal metabolism (MSIASM) approach. The first application shows that accounting the metabolism of a society in both economic and biophysical terms supports a better understanding of mechanisms determining...

This research investigates the study of the concept of adaptation as a foundation to guide management in creating a planning and scheduling system. The review paper identifies theories that are being studied in relation to the process of adaptation using genetic algorithms as well as adaptive...

In this paper we analyze the evolution of city size distributions over time in a regional urban system. This urban complex system is in constant flux with changing groups and city migration across existing and newly created groups. Using group formation as an emergent property, transition...

Given the economy's complex behavior and sudden transitions as evidenced in the 2007–08 crisis, agent-based models are widely considered a promising alternative to current macroeconomic practice dominated by DSGE models. Their failure is commonly interpreted as a failure to incorporate...

Credit default swaps (CDS) which constitute up to 98% of credit derivatives have had a unique, endemic and pernicious role to play in the current financial crisis. However, there are few in depth empirical studies of the financial network interconnections among banks and between banks and...

In this paper we attempt an overview of the philosophical implications of complex systems thought, and investigate how this alternative viewpoint affects our attempts to design and utilise models for living systems. We classify the types of complex system that relate to self-organisation. The...
