MS4 Modeling Environment (MS4 Me) is a discrete event simulation system (DEVS) software developed by MS4 Systems, Inc. It has been used in the modeling of complex systems (such as a national health care system)[1] and is also covered in a discrete event simulation and systems of systems modeling text.[2][3][4][5]
MS4 Me supports the development and simulation of DEVS models via a natural language or Java. Finite Deterministic DEVS[8] (FDDEVS) models can also be quickly developed and analyzed. DEVS models can be composed into more complex systems via the use of System Entity Structures,[9] and System Entity Structures can be composed into complex systems of systems for simulation. Many different configurations of these systems can be stored and simulated via the use of pruning.[9]
