Behavior Analysis and Testing Software (BATS)

This is the latest software by Sesdyn. BATS covers functionalities of two previous model analysis software applications by Sesdyn (BTS and SiS) and also introduces new procedures and features. In summary, operations of BATS can be grouped under three categories; behavior input and preprocessing, behavior analysis, and model analysis. Behavior inputting features include reading from external files, drawing a new data, splitting/cropping existing data, extracting selections of data, applying exponential smoothing and moving average filtering techniques. Behavior analysis features include behavior classification, trend regression, autocorrelation, spectral densities, amplitude estimation, cross-correlation, summary statistics, and graphical comparison. Model analysis features include a general purpose model docking window, hypothesis tester, behavior space classifier, and behavior class mapper.

Behavior Validity Testing Software (BTS)

This is a software developed by former SESDYN members for testing the behavioral validity of system dynamics models. It consists of multiple tools and tests suitable for measuring typical dynamic pattern components (slopes, periods, amplitudes, phase shifts, mean, variance, etc) and comparing them with real data when available.

Behavior Validity Testing Software II (BTS-II)

BTS-II is an enhanced version of BTS. It has several new tools and capabilities in addition to all found in BTS. Although we recommend BTS-II, it is still a beta version in the sense that a couple of features may yield unexpected errors in some platforms, and its user guide and help tool are not yet complete.

IE 550 - Dynamics of Socio-Economic Systems

The course uses computer simulation as an experimental platform to study and analyze the dynamics of socio-economic problems. The course has two broad objectives: The first one is to learn dynamic systems approach and systems simulation as a methodology to study and understand complex, dynamic socio-economic problems. Students will learn the concepts of stocks and flows, negative and positive feedback loops, structure and causal-loop diagrams and various typical behavior patterns. The second objective of the course is to expose the students to a variety of real socio-economic case studies and demonstrate how systems approach and simulation can be used to tackle such problems. A systems simulation software will be heavily utilized through the course.

IE 533 - Systems Theory

This is a course on the philosophy, science and tools of systems theory, emphasizing various mathematical and quasi-mathematical techniques used in dynamic modeling and analysis of complex systems. Examples from socio-economic, managerial and other living systems are modeled and discussed. Low order and linear systems are initially used to introduce the main concepts, but special emphasis is eventually placed on realistic, non-linear, time-delayed complex models. Student projects and other assignments play a major role in the course. Simulation software will be used in analysis of large-scale models.

IE 489 - Introduction to Systems Science

This course is a basic introduction to systems science and systems engineering. The fundamental concepts, philosophy and historical development of systems science are reviewed. Analogical dynamic systems are first illustrated on electrical, hydraulic and mechanical examples. The generality of systems analogy is then demonstrated on industrial, socio-economic and managerial modeling examples. Analysis tools for linear dynamic systems are reviewed. Non-linear structures and mathematical solution difficulties are discussed. Equilibrium and stability analysis is presented. Simulation method and software are introduced to analyze large scale, time-delayed, non-linear dynamic systems. Stock-flow modeling and formulation principles are discussed to analyze socio-technical problems.

IE 484 - Simulation Gaming and Decision Experimentation

The objective is to teach the problems, principles and practice of decision experimentation as a simulation based method to analyze the factors affecting human performance in dynamic decision making (DDM) environments. Concepts of dynamic complexity and influence factors in DDM studies are covered. Tools for systems thinking and simulation, causal loop diagramming, stocks, flows and their dynamics are introduced. Students learn how to develop single and multiuser (network) games of dynamic simulation models. They also learn to identify appropriate game characteristics (task structures), create experimental design, run controlled experiments and analyze and interpret experimental results. Throughout the course, in the computer lab, students become participants of several experiments with simulation games related to the topics of climate change, renewable resource management, environmental pollution, wildlife management, and alike. Applications focus on environmental problems but potentially comprise many other topics related to business management and economics. Students are expected to develop skills in systems thinking, simulation, gaming and decision experimentation.

ESc 578 - Systems Modeling for Sustainable Development

This is a series of seminars on applications of "System Dynamics Method" on various problems related to the "Sustainable Development" concept. In technical and operational terms it is about "inter-generational transfer of natural and manufactured capital stocks that would be adequate and no less than the one that exists now in terms of quantity and quality". The dynamic, long-term problem orientation of the System Dynamics, and closed-loop thinking and stock-flow concepts in model conceptualization promises to be useful in the analysis of social and environmental sustainability issues.
