Abstract
AnyLogic is a multi paradigm simulation tool that brings together System Dynamics, Process-centric (AKA Discrete Event), and Agent Based approaches within one modeling language and one model development environment. AnyLogic set of primitives and library objects allows you to model manufacturing and logistics, business processes, human resources, consumers' and patients' behavior, as well as the environment (the ``background'') in their natural interaction. The object-oriented model design paradigm supported by AnyLogic provides for modular and incremental construction of large models. AnyLogic can deploy both Java applets and applications.

SDX is a high performance Fortran based Problem Solving Environment for dynamics (continuous,discrete,hybrid) related applications in science and engineering.

Abstract
Shift is a programming language for describing dynamic networks of hybrid automata, consisting of continuous-time phases separated by discrete-event transitions. A project developed at Berkeley, by California Path.
