SimEvents is a
discrete event simulation
A discrete-event simulation (DES) models the operation of a system as a ( discrete) sequence of events in time. Each event occurs at a particular instant in time and marks a change of state in the system. Between consecutive events, no change in t ...

environment. It also adds an event-based simulation engine to the time-based simulation engine in Simulink
Capabilities
SimEvents provides a graphical drag-and-drop interface for building a discrete-event model.
It provides libraries of entity generators, random number generators, queues, servers, graphical displays and statistics reporting blocks.

MATLAB (an abbreviation of "MATrix LABoratory") is a proprietary multi-paradigm programming language and numeric computing environment developed by MathWorks. MATLAB allows matrix manipulations, plotting of functions and data, implementa ...
allows customization of the process flow in a SimEvents model. A MATLAB function can be developed to represent a task-scheduling sequence, routing of parts, or production recipes in a process flow. Since the two programs are within the same tools environment, it is straightforward to generate custom random distributions of input tasks, optimize a process, as well as to generate custom statistics.
SimEvents and Simulink can be used in the same simulation model to simulate hybrid or multi-domain systems that have both time-based and event-based components.
