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.

Model a single-queue single-server system that has a Poisson arrival process and a server with constant service time. The queue has an infinite storage capacity. In the notation, the M stands for Markovian; M/D/1 means that the system has a Poisson arrival process, a deterministic service time distribution, and one server.

模型单队列单服务器系统，其中参与时间和服务时间分别以固定装置分布为1.1和1。队列具有无限存储容量。在符号中，G代表具有已知平均值和方差的一般分布;G / G / 1表示系统的参与者和服务时间由这种一般分布管理，并且系统具有一台服务器。您可以更改均匀分布的差异。您可以使用此模型来检查小的法律。

Have you ever been in a supermarket checkout and wondered why you are in the slowest line? This example shows how queuing systems can be modeled in SimEvents for this type of application. Two parallel versions of a simple model of a four register supermarket counter are presented - one that uses four separate queues and one with a single "serpentine" queue that feeds all registers.

Use a Discrete-Event Chart block to model a queue-server that can flush entities when it receives a message on the "FlushCmd" port.

Use a MATLAB Discrete Event System block to model a single server that can pause service. The input port IN receives entities to be served. Additionally, the system may receive sporadic pause commands on port PauseCmd. If the message received on the PauseCmd port carries data=1, the system pauses. The system reschedules service for the current entity when it receives a continue message on this port, i.e. a message that carries data=0.

使用MATLAB离散事件系统块写入自定义N-Server，可以使用密钥查找选择特定实体。乘客从块的端口输入，并存储在块中，直到消息到达携带查找键的关键端口。在收到此消息时，系统会调度一个“迭代”事件，在此期间它可以访问存储在其中的每个实体并输出与密钥匹配的每个实体。

当多个实体可用时，使用实体优先级序列实体偏离。该示例模拟了机场入住柜台，乘客到达乘客。乘客可以分别使用实体优先级值1,2和3建模的一流，商业类或经济舱预留。

Use SimEvents to model a process such as the boarding of an aircraft. The process consists of multiple activities such as "Disembark", "SecurityCheck", "Refueling" etc. Some activities can be done concurrently, as represented by multiple parallel paths using AND blocks. Some activities are mutually exclusive and these are represented as output paths using OR blocks. Each activity takes up non-zero time. You can use such a model to study various aspects of a process, such as bottlenecks, resource contention, latencies, etc. The model generates a single entity at the start of simulation. This entity represents the control flow in the process. The position of the entity in the model determines which activity is currently running.
