UltraDES 2.2.5.3

UltraDES

UltraDES is a library for modeling, analysis and control of Discrete Event Systems. It has been developed at LACSED | UFMG.

Before using UltraDES

Requirements:

• Supported OS: Windows, MAC OS or Linux (Mono or .Net Core).
• Your computer must have a C# capable IDE (Visual Studio, VSCode, LinqPad, etc.).
• Download the latest version of UltraDES (https://github.com/lacsed/UltraDES.git), by clicking on Clone or Download and then Download Zip ou use the UltraDES Nuget package.

First steps

• Extract all the files of the zip or tar.gz file in your working directory.
• Double click on the UltraDES.sln file.
• Congratulations, you are ready to use UltraDES!

What is inside

Initially you are going to find four projects in the Solution Explorer:

• Other examples
• Test - Modular Supervisor
• Test - Monolithic Supervisor
• UltraDES (non executable)

To read the codes, click on the file .cs inside each project.

How to run the projects

• Before running the code, you need to set the project as Startup Project.
  • On Solution Explorer select the project you want to run.
  • On the menu Project, select Set as Startup Project - Project>Set as Startup Project.
• To run the code, click on Debug menu - Debug>Start Debugging.

Creating a new project on Visual Studio

• On the menu File, select New > Project.
• On the New Project window:
  • Select Visual C# > Console App (.NET Framework).
  • Give your project a name.
  • The location of your project should be the same as the other UltraDES projects.
  • In the Solution field, choose Add to Solution.
  • Click on OK to create your project.
• Remember to set your project as Startup Project (see How to run the projects).
• Congratulations, you just created your project!

Inside your project

• In the Solution Explorer, double click on your project.
• Inside your project, right click on the item References>Add Reference...
  • On the Reference Manager window, select Projects>Solution and select UltraDES.
  • Click Ok to close the window.
• To write your code, click on the file .cs inside your project.
• On the .cs file of your project, add the UltraDES library in the header (using UltraDES;).

In your main function, add the code below to create and see your first Automaton.

Creating States

State s1 = new State("s1", Marking.Marked);
State s2 = new State("s2", Marking.Unmarked);

Creating Events

Event e1 = new Event("e1", Controllability.Controllable);
Event e2 = new Event("e2", Controllability.Uncontrollable);

Event e3 = new Event("e3", Controllability.Controllable);
Event e4 = new Event("e4", Controllability.Uncontrollable);

Creating Transitions

var t = new Transition(s1, e1, s2);

Creating an Automaton

var G1 = new DeterministicFiniteAutomaton(new[]
  {
    new Transition(s1, e1, s2), 
    new Transition(s2, e2, s1)
  }, s1, "G1");
  
  var G2 = new DeterministicFiniteAutomaton(new[]
  {
    new Transition(s1, e3, s2), 
    new Transition(s2, e4, s1)
  }, s1, "G2");

Operations with Automata

Making a Parallel composition

var Gp = G1.ParallelCompositionWith(G2); 

Showing the Automaton

 G.ShowAutomaton("G");

Other examples

For more examples on how to create more complex automata or how to use the methods, read the other projects.
