During the last few years, computer simulation has become an essential tool for the design and evaluation of complex Systems of Systems (SOS). SOS includes air and ground transportation networks, military C4ISR multi-agent systems, and complex, international business organizations.  These systems are difficult to understand because each agent (system) in the network adapts its behavior in response to knowledge received from other agents. Agents, adapting in collaboration with other agents, lead to emergent behavior that is much more complex than any agent could achieve alone.  Such Complex Adaptive Systems (CAS) have the potential of much greater capability and effectiveness than traditional systems if designed properly.

A state-of-the-art graphical, discrete event simulation library that works with ExtendSIM (ImagineThatInc

) is available for your evaluation. This library is called Operational Evaluation Modeling for Context-Sensitive Systems (OpEMCSS), and it has the power of much more costly, general-purpose simulation products.  OpEMCSS provides the ability to examine important elements in the problem space and to allow the formulation of alternative solution concepts. OpEMCSS facilitates unconventional “out-of-the-box” thinking to discover the underlying system problems and exploit the best alternatives in the solution space without focusing on a point design too soon. In order to simulate various operational scenarios, OpEMCSS includes blocks to model agent motion and spatial interactions, agent communication and knowledge sharing, and intelligent rule-based decision-making. See OpEMCSS documents or Wiley textbook for further details.

The latest version of the Classifier Event Action block in OpEMCSS7 and OpEMCSS8 can learn a sequence of rules that optimizes the total reward from the environment. Such behavior is called reinforcement learning. Run GRIDWORLD.mox as a demonstration of reinforcement learning.

My textbook, Simulation-Based Enginee. ring of Complex Systems,” can be ordered from John Wiley and Sons direct or from Amazon.com. Appendix A instructs the reader in how to use the OpEMCSS library blocks to simulate complex systems. While learning to use the OpEMCSS library blocks you will also gain an understanding of the basic principles of complex systems; further, methods for simulation-based engineering of complex systems can be mastered by reading my book. A complete instructor’s manual that accompanies my textbook can be obtained online from WILEY. Send an Email to jclymer@fullerton.edu to obtain instructions on how to download it.

You can download any of the following WINZIP files containing libraries, models, or documents by clicking on the highlighted name.

OpEMLIB8.ZIP is a zip file that contains four simulation libraries.  OpEMCSS8.LIX and OpEMAUX8.LIX are two of the simulation libraries that work with ExtendSIM, ExtendSIM-LT (student version), and the ExtendSIM DEMO version available free from Imagine That Inc. Here is a zip file MODELS8.ZIP containing a set of OpEMCSS8 simulation models you can run.

OpEMLIB7.ZIP is a zip file that contains four simulation libraries.  OpEMCSS7.LIX and OpEMAUX7.LIX are two of the simulation libraries that work with ExtendSIM. Here is a zip file MODELS7.ZIP containing a set of OpEMCSS7 simulation models you can run.

Earlier versions of OpEMCSS, OpEMLIB6.ZIP and OpEMLIB5.ZIP, are also still available including OpEMCSS models, MODELS6.ZIP and MODELS5.ZIP.

DOCUMENTS.ZIP contains two papers that document some of the OpEMCSS library blocks and how to use them to build a simulation of your system.  Each of the OpEMCSS blocks has a help button at the bottom of its dialog box that provides more detailed documentation. Appendix A of my textbook instructs the reader in how to use the OpEMCSS library blocks to simulate complex systems.

You can arrange a one-week short course on how to use the OpEMCSS7 or 8 library to solve your simulation problems.  Send an E-mail message describing your interest in having such a course at your location. One day tutorials and half day seminars are also possible.
