ExtendSim is a simulation software for discrete event, continuous, discrete rate and agent-based simulation.

Discrete Event Simulation Advantages
Discrete Event Simulation In Healthcare

Discrete Event Simulation A discrete event simulation is a computer model that mimics the operation of a real or proposed system, such as the day-to-day operation of a bank, the running of an assembly line in a factory, or the staff assignment of a hospital or call center.
AnyLogic The AnyLogic Company A general purpose multimethod modeling tool. Arena (software) Rockwell Automation A discrete event simulation program that also allows modeling of continuous processes. Care pathway simulator SAASoft Ltd. A discrete event simulation program specifically designed for service industries e.g.
Popular Answers ( 2) There is NO best software tool. Moreover, the particular discrete event simulation package is NOT that important. There are literally dozens of commercially available DES packages, e.g. Simul8, arena, promodel, simio, anylogic, flexsim, processmodel, etc, etc, as well as free cloud-based packages.

This is a list of notable discrete event simulation software.
