A graphical discrete event simulation library is proposed for system simulation that is based on interacting concurrent processes. This library works with EXTEND (Imagine That Inc), an inexpensive yet capable and easy to use simulation software package, and it is called Operational Evaluation Modeling for Context-Sensitive Systems (OpEMCSS). Context-Sensitive Systems (CSS) is a systems theory, based on finite state machines, that can assist a systems engineering manager, business operations manager, or manufacturing production manager in understanding, evaluating, and optimizing production work flow, represented as communicating concurrent (parallel) processes. CSS theory can be expressed using the OpEM graphical modeling language. Thus, OpEMCSS is a graphical simulation library that can model systems based on CSS theory and the OpEM language. A simple part production problem is discussed that is an example of applying the Classifier Event Action block, which is a rule based classifier contained in OpEMCSS, to discover optimal rules to manage the workflow.
