The sizes of these arrays are controlled by some simulation parameters that can only be determined during the runtime. Only the server is different. The server we are going to build for this example is a more powerful server called MultiServer that can be viewed as a composition of multiple servers that runs independently.

It is capable of supporting any number of FIFO queues. The number of sources, FIFO queues and sinks are configurablei. There is only one difference though. Since there are no inport arrays, packets arriving at the MultiServer must contain an integral id to identify the source and the FIFO queue from which they are coming from.

This also explains why inport arrays are not essential: a single inport can act as an inport array if we can find a way to distinguish different sources, based on either one of the arguments or some special field contained in the data being passed. First, the outport are declared as an array, so an outport array is actually a collection of almost identical outports, except each of which is assigned a unique index.

Second, we must allocate enough memory for holding multiple packets being serviced. As mentioned before, the inport in is actually connected to multiple outports from different FIFO queues. So to determined from which the incoming packet arrive, MultiServer must look at the field indexwhich contains the id of the Source component on which the packet was created.

Notice the declaration of the timer wait. Please refer to the manual for more details. Now we need a Setup function. In this function we must allocate enough space for holding packets according to the value of the parameter size. SetSize is a predefined function for outport arrays which must be called before they can ever be used. The field index in the packet is very important. This index is used to tag the event scheduled. We can think of a timer as a timerarray in which each imaginary timer is identified by a unique index.

Once a departure event is activated, the index of that event is returned as the second argument. We must always first set the size of the component arrays, by calling there predefined SetSize functions. We then assign values to the parameters of every component in each component array we cann't do it at once. SetSize size ; next. SetSize size ; fifo. SetSize size ; sink.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

This small project has only one file with all codes. All need to simulate is to run the MM1. To run this simulator, your machine needs to have Python 3 installed and matplotlib library.

On a Linux machine, this can be installed as follows for example. By default the debug mode is disabled, but once enabled, the file will print logs as of different timestamp event and will generate a CSV file with detailed data. The simulator code is in the MM1.

Tags queueing, theory. Queueing-tool is a package for simulating and analyzing networks. It is an event based simulator that uses queues to simulate congestion and waiting on the network that includes tools for visualizing network dynamics. Prerequisites: Queueing-tool runs on Python 2. You will need to install matplotlib as well if you want to plot. Installation : To install from PyPI use:. The above will automatically install networkx and numpy.

If you want to install all optional packages, use:. Please report any bugs or issue that you find there. Of course, pull requests are always welcome.

Given an arrival rate lambda, a mean service time Ts, and a run time, the controller will generate arrival events to the system based on a Poisson process--meaning that each arrival time is set as the previous arrival time plus some exponentially distributed random variable with input lambda.

Additionally, a monitoring event which gathers statistics about the system will be called based on an exponential distribution with some input rate. Skip to content.

You signed out in another tab or window.Queueing theory is the mathematical study of waiting in lines, or queues.

Queueing theory, along with simulation, are the most widely used operations-research and management-science techniques.

Queueing Models with R

A queueing system is characterized by three components: arrival process, service mechanism, and queue discipline.

The two main inputs for any queue system are:. Common options for A and B are:. When k and m are not specified, it is assumed they are infinite.

Multiple M/M/1 Simulation

The queueing R package contains multiple functions for analyzing queueing systems. Now that we have obtained the most relevant performance measures with the Report function, it would be interesting to plot the distributions of the arrival and service processes.

Building mathematical models to predict queue lengths and waiting times might be a challenging task depending on the complexity of the system under study. However, Averill M. Law suggests the following sequence of steps in his book Simulation Modeling and Analysis to design or analyze a complex system through a simulation study:.

The queueing R package allows studying and obtaining results from multiple queueing systems with just a few lines of code, as in the example previously analyzed. While there are other simulation software available that might require you to purchase a license e. If you found this article useful, feel welcome to download my personal codes on GitHub.
