离散事件仿真

进行离散事件系统建模和仿真

要在 Simulink^® 环境中进行离散事件系统建模和仿真，请考虑使用 SimEvents^® 软件。

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性。使用队列、服务器、交换机和其他预定义的模块，您能够为调度和通信的路由、处理延迟和优先级建模。

M/M/1 Queuing System

Model a single-queue single-server system with a single traffic source and an infinite storage capacity. In the notation, the M stands for Markovian; M/M/1 means that the system has a Poisson arrival process, an exponential service time distribution, and one server. Queuing theory provides exact theoretical results for some performance measures of an M/M/1 queuing system and this model makes it easy to compare empirical results with the corresponding theoretical results.

Effects of Communication Delays on an ABS Control System

How stochastic network traffic causes timing latency and uncertainty in an anti-lock braking system that uses CAN communications.

Modeling Hybrid Systems - Tank Filling

A hybrid system with both continuous time and discrete event sections. The discrete event part models tanks, represented by entities, which are being queued and need to be filled up. Each tank has a "Capacity" attribute. The continuous time part models the process of filling up a tank, modeled by an Integrator. When a tank is filled to capacity, this event can be detected by a Hit Crossing block, which will generate a message corresponding to this event. The generated message will trigger the server to release the tank.
