Causality in complex systems

PurposeThe purpose of this paper is to show that transmission of information and information storage or registration depends on structures. Structures emerge from coordinated sets of constraints. Complex systems depend on their structures to function. The temporal sequence of changes in the levels of the complex system determines its behavior. These three concepts are intimately linked with the environment. Environment, structure, function and behavior form a complex system–environment unit, which is the operational unit of existence for all open complex systems. Therefore, it becomes a point in the directional propagation of the cause, where stimulus environment becomes a Creaon, and then the Creaon becomes a Genon, becoming in turn the response to the experienced environment. The formation of structures is the main phenomenon of evolution. Evolution can also be accepted as free, in the sense that it does not cost additional deaths.Design/methodology/approachMathematical and logical development of the structure and thermodynamics in complex systems.FindingsBased on the above considerations, the authors are going to introduce two fundamental principles in Complex systems Theory: the Matthew Effect and the Principle of Sagan.Originality/valueBut as the authors’ purpose is to give a formal definition of a complex system from a totally theoretical point of view, they establish a relationship between concepts of General Systems Theory, Theory of the Environment, linguistics, Information Theory and thermodynamics.

“…Therefore, a modeling method of the complex products design is proposed to solve these problems. In recent years, many studies have shown that systems with hierarchical structure and complicated internal relations can be modeled by complex network theory (Chen et al , 2004; Cruz et al , 2006; Hu et al , 2013; Su et al , 2017; Su et al , 2018; Usó-Doménech et al , 2017; Zou et al , 2013). For example, the complex networks were used to deal with intertwined problems among the logistics network, information network and financial network.…”

Purpose Because of the multiple design elements and complicated relationship among design elements of complex products design, it is tough for designers to systematically and dynamically express and manage the complex products design process. Design/methodology/approach To solve these problems, a supernetwork model of complex products design is constructed and analyzed in this paper. First, the design elements (customer demands, design agents, product structures, design tasks and design resources) are identified and analyzed, then the sub-network of design elements are built. Based on this, a supernetwork model of complex products design is constructed with the analysis of the relationship among sub-networks. Second, some typical and physical characteristics (robustness, vulnerability, degree and betweenness) of the supernetwork were calculated to analyze the performance of supernetwork and the features of complex product design process. Findings The design process of a wind turbine is studied as a case to illustrate the approach in this paper. The supernetwork can provide more information about collaborative design process of wind turbine than traditional models. Moreover, it can help managers and designers to manage the collaborative design process and improve collaborative design efficiency of wind turbine. Originality/value The authors find a new method (complex network or supernetwork) to describe and analyze complex mechanical product design.

Purpose The purpose of this study is to examine the unintended consequences of actions as one of the central and constituent elements of sociological theory and long debated in the history of sociology. This question has been treated under varying sociological terminologies, including, providence, social forces, social paradoxes, heterogeneity of ends, immanent causality and the principle of emergency. Design/methodology/approach This paper is concerned with “adverse effects”. The thematic contexts of “unintended consequences of social action” the authors wish to focus attention on are specific types of consequences which may merit the adjective “adverse”. Findings The analysis of the intentions of our actions and their unwanted or foreseen consequences allows us to understand how societies work. Many historical facts are probably “unintentional.” But, most continuous or changing life forms must be interpreted as a mixture of intentional (social reproduction) and unintentional consequences (social change). Originality/value This paper focuses on four points of view: the object of sociology, the problems of order and social change, the methodological status of the discipline and the nature of social explanation, and mathematical theory. Four classifications of unintended consequences are formulated from the works of Boudon, Baert and Ramos, as well as the authors.
