Description:This textbook offers an accessible yet technically-oriented introduction to the modeling and analysis of complex systems. The topics covered include: fundamentals of modeling, basics of dynamical systems, discrete-time models, continuous-time models, bifurcations, chaos, cellular automata, continuous field models, static networks, dynamic networks, and agent-based models.
In terms of organization, the book is intuitively sectioned in three parts. The first part starts with an overview of complex systems basics. The second part covers introductory material for formal/mathematical modeling of complex systems. The third part deals with modeling complex systems with a large number of variables.
Chapter 10 introduces interactive simulation of complex systems using PyCX. Chapter 11 and 12 focus on the modeling and analysis of cellular automata models. Continuous field models are described next in Chapter 13 and 14. Chapter 15 introduces network models and is followed by three chapters on the modeling and analysis of dynamic networks both in terms of topology as well as dynamics. The final Chapter 19 introduces agent-based models.
I recently completed a large distribution center modeling project using FlexSim simulation software. I was extremely impressed by the support that I received and the flexibility of FlexSim to model this complex (and massive) system. In the end, the project was considered a success and great investment by the client. The project team was able to use the model to validate the concept design performance over the planning period, identify opportunities for design improvement, and clarify/refine a shared understanding of how the system will actually work. I would highly recommend FlexSim as a modeling tool for large-scale systems based upon this experience.
The American Meteorological Society/Environmental Protection Agency Regulatory Model Improvement Committee (AERMIC) was formed to introduce state-of-the-art modeling concepts into the EPA's air quality models. Through AERMIC, a modeling system, AERMOD, was introduced that incorporated air dispersion based on planetary boundary layer turbulence structure and scaling concepts, including treatment of both surface and elevated sources, and both simple and complex terrain. As of December 9, 2006, AERMOD is fully promulgated as a replacement to ISC3, in accordance with Appendix W (PDF)(54 pp, 761 K, 01-17-2017).
There are two input data processors that are regulatory components of the AERMOD modeling system: AERMET, a meteorological data preprocessor that incorporates air dispersion based on planetary boundary layer turbulence structure and scaling concepts, and AERMAP, a terrain data preprocessor that incorporates complex terrain using USGS Digital Elevation Data. Other non-regulatory components of this system include: AERSCREEN, a screening version of AERMOD; AERSURFACE, a surface characteristics preprocessor, and BPIPPRIM, a multi-building dimensions program incorporating the GEP technical procedures for PRIME applications.
With Systems Tool Kit (STK), you model complex systems inside a realistic and time-dynamic three-dimensional simulation that includes high-resolution terrain, imagery, RF environments, and more. Select, build, or import precise models of ground, sea, air, and space assets and combine them to represent existing or proposed systems. Simulate the entire system-of-systems in action, at any location and at any time, to gain a clear understanding of its behavior and mission performance.
Ansys STK enables you to create multidomain scenarios that extend simulation beyond systems to an interactive model of the operational environment. Define and understand complex relationships between objects and analyze their performance over time.
STK's Analyzer capability blends the engineering analysis capabilities of ModelCenter with STK. Explore the design space of your systems with parametric studies, carpet plots, Design of Experiments (DOE) tests, probabilistic analysis, and optimization algorithms.
The Ph.D. in Systems Modeling and Analysis is offered jointly by the Department of Statistical Sciences and Operations Research and the Department of Mathematics and Applied Mathematics. The program focuses on the development of the mathematical and computational skills used to conceptualize and analyze real-world systems. Faculty and students will engage and collaborate to contribute to the knowledge base used in the fields of science, medicine, business and engineering. The continued development of applied mathematics, discrete mathematics, operations research and statistics is critical to scientific advancement in the 21st century. The curriculum enables students to expand the frontiers of knowledge through original, relevant research involving quantitative and qualitative complex systems derived from real, contemporary problems facing our world.

MBDyn is being actively developed and used in the aerospace (aircraft, helicopters, tiltrotors, spacecraft), wind energy (wind turbines), automotive (cars, trucks) and mechatronic fields (industrial robots, parallel robots, micro aerial vehicles (MAV)) for the analysis and simulation of the dynamics of complex systems.
You can fill in a series of values that fit a simple linear trend or an exponential growth trend by using the fill handle or the Series command. To extend complex and nonlinear data, you can use worksheet functions or the regression analysis tool in the Analysis ToolPak Add-in.
Simulation models have been widely used to study and analyse complex real-world systems in the design of many modern products, such as vehicles, civil structures and medical devices (Zhou et al. 2016a, 2017). Various types of engineering tasks utilize simulation models, including design space exploration, design optimization, performance prediction, operational management, sensitivity analysis and uncertainty analysis. There are also various problems, such as model calibration and model parameter sensitivity analysis, related to enhancing the ability of simulation models to faithfully reproduce real-world systems (Razavi et al. 2012).
Mediation analysis is not limited to linear regression; we can use logistic regression or polynomial regression and more. Also, we can add more variables and relationships, for example, moderated mediation or mediated moderation. However, if your model is very complex and cannot be expressed as a small set of regressions, you might want to consider structural equation modeling instead.
Operate and manage your infrastructure and development processes at scale. Automation and consistency help you manage complex or changing systems efficiently and with reduced risk. For example, infrastructure as code helps you manage your development, testing, and production environments in a repeatable and more efficient manner.
Organizations might also use a microservices architecture to make their applications more flexible and enable quicker innovation. The microservices architecture decouples large, complex systems into simple, independent projects. Applications are broken into many individual components (services) with each service scoped to a single purpose or function and operated independently of its peer services and the application as a whole. This architecture reduces the coordination overhead of updating applications, and when each service is paired with small, agile teams who take ownership of each service, organizations can move more quickly.
Further investigation of self-organizing systems reveals that the divine creator, if there is one, does not have to produce evolutionary miracles. He, she, or it just has to write marvelously clever RULES FOR SELF-ORGANIZATION. These rules basically govern how, where, and what the system can add onto or subtract from itself under what conditions. As hundreds of self-organizing computer models have demonstrated, complex and delightful patterns can evolve from quite simple evolutionary algorithms. (That need not mean that real-world algorithms are simple, only that they can be.) The genetic code within the DNA that is the basis of all biological evolution contains just four different letters, combined into words of three letters each. That pattern, and the rules for replicating and rearranging it, has been constant for something like three billion years, during which it has spewed out an unimaginable variety of failed and successful self-evolved creatures.
