Event-Based Modeling
The MathWorks® products for event-driven systems have applications for the automotive, aerospace, or robotics and automation industries. Your event-based applications can focus on communications, supervisory logic and scheduling, and operations research.
Stateflow® provides a graphical language that includes state transition diagrams, flow charts, state transition tables, and truth tables. You can use Stateflow to describe how MATLAB® algorithms and Simulink® models react to events and time-based conditions. With Stateflow you can design and develop supervisory control, task scheduling, fault management, communication protocols, user interfaces, and hybrid systems.
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. With SimEvents, you can study the effects of task timing and resource usage on the performance of your system and conduct operational research for decisions related to forecasting, capacity planning, and supply-chain management.
