SimEvents is a discrete event simulation tool developed by The MathWorks. It adds a library of graphical building blocks for modeling queuing systems to the Simulink environment. It also adds an event-based simulation engine to the time-based simulation engine in Simulink

Process/Logistics simulation
SimEvents is used to model process flows and logistics in order to understand resource availability, inventory management techniques, and the effects of arbitrary events on a mission plan.

For example, SimEvents can simulate manufacturing processes for capacity planning and production planning.

SimEvents is also used to simulate logistics of vehicle maintenance schedule. Such a model may include: A SimEvents model can be used to estimate through-life support (TLS) requirements such as the size of repair pools, provisioning of spares. A SimEvents model can also predict characteristics such as availability, serviceability and end-to-end latencies based on a specific maintenance schedule.
 * Generation of repair demand based on mean times between failures and repairs
 * Different failure types with specific maintenance requirements
 * Pool of maintenance resources

Modeling performance of a system architecture
SimEvents is used to build a discrete-event model of the architecture of an electronic system. This architecture model simulates the transactions between different components such as processors, memory, or a communication bus. Simulation of this model provides insight into performance characteristics such as throughput, latency, packet loss and utilization. Systems engineers can use this model to understand the constraints on various shared resources in the electronic system

Capabilities
SimEvents provides a graphical drag-and-drop interface for building a discrete-event model. The modeling environment also includes multiple abstraction mechanisms to provide visual hierarchy and to create a custom user-interface for a subsystem.

Library blocks
SimEvents provides libraries of entity generators, random number generators, queues, servers, graphical displays and statistics reporting blocks.

Use of MATLAB in a discrete event simulation
Integration with MATLAB allows customization of the process flow in a SimEvents model without low-level programming. A MATLAB function can be developed to represent a task-scheduling sequence, routing of parts, or production recipes in a process flow. Since SimEvents and MATLAB are within the same tools environment, it is straightforward to generate custom random distributions of input tasks as well as to generate custom statistics from a SimEvents model using a MATLAB function.

Multi-domain simulation
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.
