Mathematical Simulation and Modelling Applications

The tasks include mathematical simulation and modelling need lots of parallel processing. Three fundamental formalisms in mathematical simulation and modelling are 'Discrete Time System Simulation (DTSS)', 'Differential Equation System Simulation (DESS)' and 'Discrete Event System Simulation (DEVS)'. All other formalisms are the combinations of these three formalisms. DEVS is the most accepted. Thus many software tools have been designed especially for DEVS.  A number of such softwares are:

• Parsec which is a C-based simulation language for both sequential and parallel execution of discrete-event simulation models.
• Omnet++ a discrete-event simulation software development environment written in C++.
• Desmo-J, "Discrete event simulation framework" works in Java.
• Adevs (A Discrete Event System simulator) is a C++ library for constructing discrete event simulations based on the Parallel DEVS and Dynamic Structure DEVS formalisms.
• Whichever Logic is a professional simulation tool for complex discrete, continuous and hybrid systems.
