Complex lighting system

Šipr, Jan · Brno University of Technology Digital Library (Brno University of Technology) · 2015

Tato práce se zabývá teoretickými základními principy osvětlování a jejich regulace. Na základě teoretických poznatků bylo úkolem navrhnout osvětlovací systém šitý přímo na míru. Dále jsou zde popsány komunikační protokoly používané v osvětlovací technice (DMX a ArtNet).

Complex System Reliability

Todd Silvestri · The Mathematica Journal · 2014

We demonstrate a method of generating an exact analytical expression for the reliability of a complex system using a directed acyclic graph to represent the systems reliability block diagram.Additionally, we show how statistical information stored in a reliability block diagram can be used to transform an analytical expression into a time-dependent function for system reliability.

Complex system reconstruction

Haifeng Zhang, Wen-Xu Wang · Acta Physica Sinica · 2020

Open complex systems far from equilibrium widely exist in the nature and the fields of society and technology, which are the main research objects of complexity science. Through the exchange of energy and material with the outside world, complex systems can form a variety of internal structures, orders and laws by self-organization behaviors, which poses an arduous challenge to the understanding and predicting complex systems. With the improvement of experimental technology and the progress of science and technology, the data reflecting the mechanism of various complex systems are increasing exponentially, thereby providing new opportunities for studying complex systems. Revealing the structures and dynamics of complex systems from the measured data is an inverse problem in the field of physics, which is the premise of understanding complex systems, predicting the evolution of system state, and regulating system state. However, it is very difficult to solve this inverse problem due to the diversity and complexity of complex system. Therefore, we need to fully mine the hidden knowledge and deep mechanism in the data with the help of interdisciplinary integration. In this paper we briefly review the research results of complex system in recent years, especially the reconstruction of complex network structures, hoping to inspire the innovation to the inverse problem of complex systems. Meanwhile, we hope that researchers in different fields can pay much attention to the inverse problems of complex systems, promote the cross and integration of nature, society, economy, biology and technology, and solve the scientific problems that we are facing.

COMPLEX, MODEL, SYSTEM

Tokarev M.V. · Zenodo (CERN European Organization for Nuclear Research) · 2022

The article discusses artificial, natural systems and complexes. Natural systems cannot be such, because, by definition, a system is a set of elements and relationships between them. Unlike artificial systems, in natural systems it is often impossible to establish such sets. Scientists are forced to build models of natural systems and subject the models themselves to system analysis.

Complex system design technique

Stelian Brad · International Journal of Production Research · 2008

The development of concepts for new generations of products that are located at the convergence of various cutting-edge technologies requires: integration of knowledge from different fields of science and technology; the management of non-linear interactions of technical, cognitive and organizational nature; the handling of multiple and inconsistent information; innovative solving of negative correlations between different system's characteristics, etc. Despite specialists’ experience, empirical approaches to the synthesis process for this category of products do not represent a reliable solution. An innovative tool for the systematic management of the synthesis process of complex innovative products is introduced in this paper. It is called the complex system design technique (CSDT) and incorporates a set of coefficients and a specific algorithm that take data from product performance planning process (e.g. data extracted from QFD-type matrices) for the formulation of a working scheme for system design (WSSD). This scheme represents a practical tool for the new product synthesis (design) process. It also allows systematic integration of innovation and analysis tools (e.g. TRIZ, AFD, Pugh, Design-FMEA, etc.) in the product synthesis process.
