SimEvents for Operations Research

SimEvents® provides a discrete-event simulation engine and component library for analyzing event-driven system models and optimizing performance characteristics such as latency, throughput, and packet loss. Queues, servers, switches, and other predefined blocks enable you to model routing, processing delays, and prioritization for scheduling and communication.

With SimEvents you can study the effects of task timing and resource usage on the performance of distributed control systems, software and hardware architectures, and communication networks. You can also conduct operational research for decisions related to forecasting, capacity planning, and supply-chain management.

SimEvents® provides a discrete-event simulation engine that manages and processes sequences of asynchronous events. These events can help model mode changes and trigger state transitions within time-based systems in Simulink®.

With SimEvents you can create entities to represent discrete items of interest, such as packets in a communication system or airplanes in an airport taxiway. The generation, movement, and processing of entities in the system causes events, such as the arrival of a packet or the departure of an airplane. In turn, these events modify the states in the system to affect system behavior. You can characterize your entities with attributes, such as a destination address, processing time, or server delay. Entities can also acquire and release resources, which can represent supplies, machines, or even people that entities use to complete a task or event. SimEvents distinguishes between entity lines, which represent entity movement between blocks and event-signal lines, which denote corresponding event-based computations, via unique port styles.
