Complexity Science or Complex System Theory originates from the research fields such as Mathematics, Economics, and Biology. It covers many different disciplines, including Complexity Theory, Catastrophe Theory, Dissipative Structure, Chaos Theory, Fractal Theory, and Self-Organized Criticality, etc., and can be generally called “complexity science perspective”. Due to the fast-changing environ...

The purpose of this paper is to develop a systems theory-based construct for pathologies within the context of complex system problem formulation. Problem formulation is arguably one of the most critical phases of any endeavour to improve systems. However, there is relatively little research utilising systems theory during problem formulation. A possible extension of the systems research is the...

The Philosophy of Blockchain Technology is concerned, among other things, with its ontology, how might it be characterised, how is it being created, implemented, and adopted, how does it operate in the world, and how does it evolve over time. Here, we concentrate on whether Bitcoin/blockchain can be considered a complex system and, if so, whether a chaotic one. Beyond mere academic curiosity, a...

Subject of research is complex networks and network systems. The network system is defined as a complex network in which the flows are moved. Classification of flows in the network is carried out on the basis of ordering and continuity. It is shown that complex networks with different types of flows generate various network systems. Flow analogues of the basic concepts of the theory of complex ...

Information Theory concepts and methodologies conform the background of how communication systems are studied and understood. They are mainly focused on the source-channel-receiver problem and on the asymptotic limits of accuracy and communication rates, which are the classical problems studied by Shannon. However, the impact of Information Theory on networks (acting as the channel) is just sta...

Starting with my acquaintance with W. Ross Ashby, this paper offers an account of one aspect of his work, information theory. It shows his motivation to embrace information theory, how he extended it, where it failed while fertilizing reconstructability analysis, and what it took for a solution to emerge. Based on Ashby‘s recognition of the material limits of computation, the paper continues hi...

A recent trend in the literature has been to characterize healthcare activities in terms of complex systems theory. Complexity has often been loosely and variously defined, with meanings ranging from "not simple" to "complicated" to "intractable." In this paper, we consider various aspects of complexity and how they relate to modern healthcare practice, with the aim of developing research appro...
