基于事件建模

对事件驱动的系统进行建模、仿真、测试和优化

针对事件驱动系统的 MathWorks^® 产品适用于汽车、航空航天或机器人和自动化行业。基于事件的应用程序可以专注于通信、监督逻辑和调度以及运筹学。

Stateflow^® 提供了一种图形语言，包括状态转移图、流程图、状态转移表和真值表。您可以使用 Stateflow 来描述 MATLAB^® 算法和 Simulink^® 模型如何对基于事件和时间的条件作出反应。您可以使用 Stateflow 来设计和开发监控、任务调度、故障管理、通信协议、用户界面和混合系统。

SimEvents^® 提供一个离散事件仿真引擎和组件库，用于分析事件驱动的系统模型以及优化延迟、吞吐量和数据包丢失等性能特征。借助 SimEvents，您可以研究任务时间安排和资源使用对系统性能的影响，并为与预测、产能规划和供应链管理相关的决策执行运营研究。
