In this paper, an optimal adaptive sliding mode controller is proposed for anti-synchronization of two identical hyperchaotic systems. We use hyperchaotic complex T-system for master and slave systems with unknown parameters in the slave system. To construct the optimal adaptive sliding mode controller, first a simple sliding surface is designed. Then, the optimal adaptive sliding mode controll...

On the basis of reviews on related literatures based on complexity science and complex adaptive system of supply chain management research, the development process of supply chain management has been analyzed, and several advantages to apply complex adaptive system in supply chain management research have been put forward. It has broad application prospects to study the coordination development...

In this paper, we describe how traditional systems engineering processes, such as those delineated in the ANSI//EIA 632 standard, are becoming inadequate for today’s complex systems, in which there is a rich set of interconnections and interrelationships between all of the systems in an enterprise. We further suggest that a new discipline (or an extension of the old discipline) is developing in...

We present a review of complex systems research which focuses on their similarities with self-organizing living systems. We classify the types of complex systems that relate to self-organisation and we discuss the overall requirements for self-organising modeling. As a novelty, the paper proposes a methodology to aid engineers in the design and control of adaptive complex systems. The methodolo...

This commentary addresses two points raised by Kitson and colleagues’ article. First, increasing interest in applying the Complexity Theory lens in healthcare needs further systematic work to create some commonality between concepts used. Second, our need to adopt a better understanding of how these systems organise so we can change the systems overall behaviour, creates a paradox. We seek to m...

Language arises from the interaction of three complex adaptive systems — biological evolution, learning, and culture. We focus here on cultural evolution, and present an Iterated Learning Model of the emergence of compositionality, a fundamental structural property of language. Our main result is to show that the poverty of the stimulus available to language learners leads to a pressure for lin...
